bar fender meaning in English
防撞杆
Examples
- On the basic of a great of literature reading and research on safety of side impact of the car , according to requirement of ece r95 , applied madymo6 . 2 . 1 software , established simulation model of side impact of the car , researched the relationship between side rigidity of the car and passenger injury in side impact , which showed that during first impact the bigger side rigidity was , the more advantaged protection for the car and passenger in a definite range , and which drew a conclusion that the most serious part of passenger injury was pelvis during first impact . then detailed the substructure model by defining bodies , joints , contact types and contact characteristic , researched some improvement approach for side safety of the car , and then analyses a particular case , that was to say to fix vehicle door bar fender on between inner and outer plate of the vehicle door , analyzed the influence of passenger injury when the bar fender was fixed on different position , the result showed that the passenger injury was less when the bar fender was fixed on the height of vehicle door decorate bar . finally , a set of tests were performed , contrasting the simulation result with the test , analyzed the influence of the side rigidity of the car to passenger injury , which showed the test
本文在对汽车的侧面碰撞安全性进行大量文献阅读和研究的基础上,按照欧洲ecer95侧面碰撞乘员保护法规的要求,应用多刚体动力学软件madymo6 . 2 . 1 ,建立了汽车的侧面碰撞仿真模型,研究了汽车的侧面刚性对乘员损伤的影响,结果表明在“一次碰撞”中,在一定范围内汽车侧面刚性越大,越有利于汽车和乘员的保护,同时得出结论,即在“一次碰撞”过程中人体损伤最严重的部位是骨盆;然后通过定义各刚体、铰链、接触类型以及接触特性,对该模型进行子结构细化工作,研究了加强汽车侧面安全性的若干改进措施,并进行了一个特例分析,即在此模型的车门内外板之间安装了车门防撞杆,分析了当车门防撞杆安装在不同位置时对乘员损伤的影响,结果表明防撞杆位于车门装饰条的高度时,对乘员的损伤较小;最后进行了一组侧面碰撞试验,通过试验和仿真结果的对比,分析汽车的侧面刚性对乘员损伤的影响,表明试验和仿真结果是一致的,从而证明了仿真模型的有效性以及仿真结果的正确性。
