<p style="white-space: normal; line-height: 2em;"><span style="color: rgb(89, 89, 89);">完成了方向盘骨架的制作，下一步就是给方向盘套上皮套了，下图就是加上皮套后的方向盘，很明显中间裸露的部分就是安装气囊模块的区域。</span></p>
<p style="white-space: normal; line-height: 2em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2019/02/14981550201168.jpg" guid="6dcba9bd-cf43-4147-9ced-1e886af37271" id="6dcba9bd-cf43-4147-9ced-1e886af37271" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 2em;"><span style="color: rgb(89, 89, 89);">安全气囊模块其实并不神秘，像下图这种就是了。现在的安全气囊都很高级，属于集成式的，所以我们习惯上称它为「模块」。</span></p>
<p style="white-space: normal; line-height: 2em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2019/02/51531550201168.jpg" guid="e4046066-1303-4912-8b48-aa5c97f56b2e" id="e4046066-1303-4912-8b48-aa5c97f56b2e" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 2em;"><span style="color: rgb(89, 89, 89);">当然你会问安全气囊模块的反面是什么样子，其实它的反面就是方向盘中间的盖板，一般厂家会在这里设计自家品牌的logo，增加辨识度。</span></p>

<p style="white-space: normal; line-height: 2em;"><span style="color: rgb(89, 89, 89);">需要特别说明的是，安全气囊在爆破展开时不是无规则的直接将盖板撑开，或者盖板整体脱落，而是有针对性的沿着特定的区域展开，我们习惯将它称为气囊撕裂线或者弱化线。</span></p>
<p style="white-space: normal; line-height: 2em;"><img title="点击插入图片" src="http://www.autoju.com/wp-content/uploads/2019/02/4681550201169.jpg" guid="23d1bd4a-6d4a-46f1-a88d-f2797a1e3d47" id="23d1bd4a-6d4a-46f1-a88d-f2797a1e3d47" style="max-width: 100%;"/></p>
<p style="white-space: normal; line-height: 2em;"><span style="color: rgb(89, 89, 89);">撕裂线顾名思义，就是在设计时沿着这几条线的区域会刻意薄弱一些，通过气囊爆破挤压，这几条线就很容易撑开。</span></p>
<p style="white-space: normal; line-height: 2em;"><span style="color: rgb(89, 89, 89);">在汽车研发过程中，考察气囊爆破是不是沿着撕裂线展开是非常重要的评价指标，因为若不按此规则展开，容易发生气囊展开不均匀、不及时；或者气囊挤压盖板导致盖板脱落、大尺寸碎裂物崩出等危险情况，要知道气囊爆破的力道非常大，若硬质碎片飞出极容易伤害驾驶员。</span></p>
