<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">本文会先按车身前中后三个区域分别介绍，再给大家介绍关于结构设计的一些通用规则。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><strong>一、车身前部安全设计</strong></span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">发动机前部结构俯视图如下，我们通常称这部分为碰撞吸能区或者溃缩吸能区，以下会重点介绍前防撞梁、吸能盒、前纵梁和发动机盖的设计原则。</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/86021526870460.jpg" guid="fc22a79a-0d6e-4f3e-8ac6-5d193e37a568" id="fc22a79a-0d6e-4f3e-8ac6-5d193e37a568" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▎前防撞梁和吸能盒设计</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">前防撞梁和吸能盒属于低速安全碰撞设计，它的作用是希望能够尽可能多的吸收能量，在结构设计上，封闭槽结构会比开放式结构好，一来结构受力会更均匀不容易发生应力集中产生完全变形，再来封闭槽结构能够承受更多的力，强度也会更大。</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/97891526870461.jpg" guid="7b9a84ce-45d3-47fe-9e0e-d6863a204006" id="7b9a84ce-45d3-47fe-9e0e-d6863a204006" style="max-width: 100%;"/></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▲第二张图这种开放式的薄壁结构就不太好了，一般受力不能很大。另外，有的人喜欢通过防撞梁的厚度来评价它的安全水平，其实这种方法不太恰当，比如第一张图这种在多框架结构对安全提升反更有利。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">吸能盒的作用和它的名字一样，最大的作用是在受力强度不太大时充分吸收碰撞能量，所以在简单的薄壁框架结构上还有很大的发挥空间，比如采用溃缩引导设计。</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/77471526870461.jpg" guid="118feb55-84b1-4033-962c-3f3b65ce3d79" id="118feb55-84b1-4033-962c-3f3b65ce3d79" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">另外，它作为前防撞梁和前纵梁的连接件，吸能盒变形后需要更换，因此有拆卸功能会比直接焊死会更好。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▎前部薄壁梁设计</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/18951526870461.jpg" guid="5d834378-8c71-4419-87b0-180fc48b6ad8" id="5d834378-8c71-4419-87b0-180fc48b6ad8" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">车身前纵梁通常是薄壁梁焊接结构，在轴向受到冲击后，有两种基本的变形模式：轴向压溃和弯曲。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">轴向压溃是效率最高的变形模式，不过这种形式在受力后通常很不稳定，很容易在溃缩中途就会因应力集中直接发生弯曲。所以在前纵梁处设计一些小槽口，如角台、凹台、凸台能够较好地避免这些问题。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▎发动机盖</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/63991526870461.jpg" guid="fb4e7e0a-50b6-4524-bd15-6a1f92f68132" id="fb4e7e0a-50b6-4524-bd15-6a1f92f68132" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">按理说发动机盖不是主要的吸能件，这里没必要多讨论，不过发动机盖在受到冲击后有铰链断裂脱落的风险，碰撞严重时发动机盖有可能直接被撞入发动机舱，危及车内人员，所以就需要我们在发动机盖内板上设计一些溃缩引导设计。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">有的人以为上述这种设计是用来起到轻量化的目的，确实是这样没错，不过更重要的它还能起到溃缩引导，使得撞击力尽可能集中在这块区域，这样发动机盖在碰撞后就不会伤及车内人员了。比如下图这种就是较理想的溃缩状态。</span></p>
<p style="white-space: normal; text-align: center;"><br/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">另外，考虑到行人碰撞安全，发动机盖上尽量不要出现过多的棱线，特别是在中后部区域，因为行人在碰撞后头部首先接触这块区域。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/27471526870461.jpg" guid="c8667433-a7ef-4804-a6f6-a22aa822cafd" id="c8667433-a7ef-4804-a6f6-a22aa822cafd" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▲虽然道奇的引擎盖很帅，不过这种设计对行人其实不太友好。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><strong>二、车身中部安全设计</strong></span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">车身中部结构安全水平如何直接关系到乘客的安全，特别是没有缓冲的侧面区。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▎驾驶舱骨架受力引导</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/7681526870461.jpg" guid="53a1c58c-51ad-4aec-86cc-57d44049d37b" id="53a1c58c-51ad-4aec-86cc-57d44049d37b" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">在汽车受到较大碰撞力时，碰撞力会传递到发动机舱，通常我们希望力能够顺畅地通过，不要有明显的应力集中区域，而把力引导到纵梁上和各“大梁”汇集的区域是比较好的选择，因为这块区域通常最厚大，强度最高。</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/93361526870461.jpg" guid="806e42ee-27ae-40a3-be24-3f385927f33d" id="806e42ee-27ae-40a3-be24-3f385927f33d" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">比如马自达SKYACTIV-Body和老结构相比，在结构改进上就很明显，可以看到新结构在力传递上会更通畅，在车身中部没有明显的应力集中，新结构应力最集中的是中纵梁和后纵梁的连接处，而这块区域也是最厚大的区域。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▎中通道设计</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/30041526870462.jpg" guid="b127e8fc-98d3-46a9-ad0e-c1666fc9667c" id="b127e8fc-98d3-46a9-ad0e-c1666fc9667c" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">关于中通道设计大家平时可能不太关注，虽然它像纵梁那样需要承受很大的冲击力，但对于承载式车身而言，由于其位置居中避免不了受到冲击力。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">所以中通道的强度也必须得到保证，比宝马7系采用的碳纤维混合车身就在中通道处采用了碳纤维加强处理。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▎侧面碰撞</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">面对侧面碰撞冲击，B柱首当其冲，所以B柱本身以及上下接头的强度和刚度很重要。另外这个力会传递到门栏上，所以对门栏强度也有要求。除了建议以上区域使用高强度钢外，多层结构也是较佳的解决办法。</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/58411526870462.jpg" guid="d0e36c3f-4182-4664-8a6b-ea55d19f5cf8" id="d0e36c3f-4182-4664-8a6b-ea55d19f5cf8" style="max-width: 100%;"/></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▲比如上图，我们可以看到B柱采用了两种不同的材质，一方面强度提升了，另一方面中空结构给门锁、安全带预警器等装置都能安装在这个中空部件上。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">侧面碰撞中的结构很重要，一般在下图黄色方框区域最容易出现应力集中，所以通常这块区域需要进行加强处理。</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/86921526870462.jpg" guid="913f0a12-9fa9-4044-9bf4-85bb5e7c96c0" id="913f0a12-9fa9-4044-9bf4-85bb5e7c96c0" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><strong>三、车尾设计</strong></span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▎后防撞梁</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/11311526870462.jpg" guid="792b5d60-6f00-41dd-8493-586ace79c2c4" id="792b5d60-6f00-41dd-8493-586ace79c2c4" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">关于后防撞梁到底对汽车安全性的贡献有多大，大家说法不一，不过随着现代汽车对空间要求越来越大，车身后部区域被进一步压缩，所以装配后防撞梁是很好的缓解办法。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">不过不少后防撞梁长度较短，吸能盒溃缩区域不够，这点就不太好了。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▎后纵梁</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">车尾受到碰撞后，撞击力向车前传递的路径通常有两条，第一条是由后保险杠经后纵梁传递给门栏梁；第二条由后车轮后部结构，经后车轮传递给门栏梁。</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/43551526870462.jpg" guid="272d13af-9e4b-4409-9480-3814ecbcc428" id="272d13af-9e4b-4409-9480-3814ecbcc428" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▲现在汽车由于趋向越来越短的尾箱设计，这时候对尾箱的结构强度要求更高。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">第一条路径的原理和前部区域类似，就不再累述了；我们讲讲第二条路径，轮胎参与碰撞后，它会与轴向刚度较大的门栏梁接触，导致对撞击的抵抗明显增加，因此碰撞吸能区布置在后车轮后部区域会更好，而将后轮作为变形限制器加以利用。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><strong>四、通用设计</strong></span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">以上是按照区域来进行讨论的，另外通常汽车上还有一些通用设计。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▎框架结构有利提高扭转刚度</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/62601526870462.jpg" guid="9ada784e-30f1-469b-89a4-b41074167d01" id="9ada784e-30f1-469b-89a4-b41074167d01" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">车身扭转刚度是衡量汽车安全和舒适性的重要指标之一，其数值越大越好。而想要获得较大的扭转刚度，最好的设计方法就是增加框架结构。这并不难理解，其实很多建筑中采用了这种设计，比如过山车。</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/49551526870463.jpg" guid="c2462b7f-26ab-4163-a8b5-abe1e10e2527" id="c2462b7f-26ab-4163-a8b5-abe1e10e2527" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">关于框架结构设计各家都有所使用，不过要说最典型的还是奥迪ASF框架结构。以奥迪A8L为例，ASF白车身重量只有241kg（98%铝合金比），但其结构刚性与抗扭强度较上代提升了25%。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">▎接头设计</span></p>
<p style="white-space: normal; text-align: center; line-height: 3em; text-indent: 0em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2018/05/19701526870463.jpg" guid="e5fdfff2-0045-4476-be23-60969c1ca3a7" id="e5fdfff2-0045-4476-be23-60969c1ca3a7" style="max-width: 100%;"/></p>

<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">白车身是有各种形状、材质的钢材或者铝材通过焊接在一起的，所以焊接接头的重要性也就不言而喻了。不过关于这部分，我们一般很难用肉眼观察，所以这里仅从大方向上给大家做一些介绍。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;"><strong><strong>798</strong><strong>小结：</strong></strong></span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">车身安全设计是门大学问，本篇旨在用比较简单语言来给大家讲解有关安全设计的惯用手法，考虑到车身设计中还有重要的CAE力学分析环节，以此来调整各部分材料及力学结构设计。</span></p>
<p style="white-space: normal; line-height: 3em; text-indent: 0em;"><span style="font-family: 微软雅黑, &quot;Microsoft YaHei&quot;;">虽然我们不能绝对对号入座，不过作为惯用手法，我们还是能使用这些准则作为参考。所以以后再有人给你白车身的结构图，别只顾盯着都用了哪些材料，不妨也留意一下车身结构设计水平如何吧。</span></p>
