| 摘 要： | 提高燃油经济性已成为新车开发中的一个核心问题,其中改进燃油经济性的重要策略之一就是减轻汽车质量。为了尽可能达到轻量化的目的,分析了保险杠防撞梁的结构变量对其扭转刚度的影响,对保险杠防撞梁的截面高度、厚度的增加以及撑条的增多对其扭转刚度的影响进行了详细的研究和比较.分析结果表明,增加截面高度是提高保险杠防撞梁扭转刚度的最有效方法.此外,为了验证轻量化潜在的可行性,对由传统钢材和高强度钢制成的2种保险杠防撞梁的碰撞能力进行了分析比较.所得的分析结果为保险杠的防撞设计提供了理论依据,对保险杠的设计及结构优化具有参考价值.

| Abstract: | Increasing fuel economy has been a central issue in the development of new cars,and one of the important strategies to improve fuel economy is to decrease vehicle weight.In this study,the effects of structural variables on the torsion stiffness of a body bumper impact beam are analyzed for possible weight reduction and the effects of variation of section height,increase of impact beam thickness and the addition of stays in a bumper impact beam are carefully investigated and compared.Analysis results show th... |
