一种基于IIHS偏置碰的创新型电动汽车车身设计
|
摘要
某车型美版电动汽车是在其国内版车身的基础上开发设计,相对原车型,新的车身设计主要存在以下两大技术难点:1.电池包等新能源高压零部件部件的安装,不仅增加了整车重量,还占据大量的结构空间,使的碰撞向后的传力路径设计受限,严重增大设计难度;2.美国作为汽车强国,其相关碰撞标准法规完善,工况及评价标准非常严苛,显著高于国内碰撞安全法规,其中尤以美国高速公路协会的IIHS评价为甚。文章结合计算机辅助仿真技术,通过对车身结构的创新规划设计,特别是一种新型闭环梁的设计,设计出一款可以获得美国IIHS偏置碰车身结构GOOD评价的纯电动车身。
The American Version Electric Vehicle is developed and designed on the basis of its domestic body. Compared with the original car, the new car body design has two major technical difficulties: 1. Installation of high-voltage components such as battery pack and other new energy sources, it not only increases the weight of the vehicle, but also occupies a lot of structural space. which limits the design of the backward force transmission path of the collision, which greatly increases the difficulty of design. 2.The United States, as a powerful automobile country, has well-developed laws and regulations on collision standards, operating conditions and evaluation standards, which are significantly higher than domestic collision safety regulations, particularly the IIHS assessment of the American Highway Association. This paper combines computeraided simulation technology, through the innovative design of car body structure, especially the design of a new type of closed-loop beam, design a GOOD evaluation of the IIHS offset crash body structure in the United States.
