摘要

摘要: 以某企业提供的6120型客车为研究对象,使用Hypermesh建立大客车的有限元模型。使用LS-dyna进行仿真计算,模拟出大客车在碰撞过程中的变形和加速度随时间的变化情况。根据仿真发现的问题,提出改进措施,并进行验证。结果证明:局部的结构改善能提高客车的防撞性能,但要彻底的改善大客车的防撞性能,需要在客车整体结构上有较大改动。

Abstract: Base on the basic principle of vehicle crash analysis using the finite element method, a bus finite element model was built by using Hypermesh software. To simulate the front impact test of the bus, the LS-dyna software is adopted to calculating the deformation of the bus and the acceleration time history curves during the crashing process, the anti-impact capability of the bus is evaluated from these simulations. The results demonstrate that the improvement of local structure can promote the crashworthiness of the bus, but a major change of the vehicle structure is required to have a radical improvement of the crashworthiness of the bus.
