摘 要
 汽车问世已一个多世纪了 ,给世界带来了巨大的变化。随着人民生活水平的提高,汽车已进人平常百姓家,人们对汽车的要求也越来越高,美观性和安全性已成主题。保险杠是汽车车身的一个重要部件 ,其除起装饰作用外 ,还起保护翼子板 、散热器和灯具的作用。
 由于保险杠具有这些功能,国内外对它的研究十分重视 ,特别是轿车保险杠,众多厂家更是追求造型优美、结构独特和具有被动安全装置的保险杠。汽车保险杠安装在汽车的最前端和最后端 ,在整车造型风格中起到至关重要的作用。它能够诠释出整车外装饰的艺术风格 ,好的保险杠能够使用户感到赏心悦目,得到美的享受。无论汽车的大、小改型设计,保险杠总是成为造型师手中重点塑造的对象 ,造型美观是整车的亮点及卖点。
 另外,发生碰撞时 ,大多数情况下都有保险杠的参与,保险杠作为安全防护装置是现代汽车结构的重要组成部分,它能有效地减轻人员伤亡程度以及汽车损坏程度。
 本文针对一款小型车进行了适合小型车的低成本保险杠设计。在本设计中，作者利用PRO\E三维制图软件进行设计，着重强调了对保险杠外形曲面以及连接结构的设计，在保证了保险杠装配和装饰性能基础上尽可能降低成本，从而达到设计目的。
