摘要
运用MSC Nastran、Ls-Dyna等CAE分析软件,对轻型卡车驾驶室的结构特性进行仿真分析。建立了轻卡驾驶室有限元模型,设置载荷及边界条件,对轻卡驾驶室的模态、静态刚度、静态强度进行分析及评价。同时,根据ECE R29安全标准建立轻卡驾驶室耐撞性分析模型,对其进行正面摆锤冲击试验,通过选取驾驶员侧的相关参数进行仿真。仿真结果表明,驾驶员腿部护板到座椅垫前端的水平距离大于假人模型大腿厚度,因此,能保证有足够空间放置假人模型。
The comprehensive analysis method for cab structural characteristics of a light truck is investigated with CAE analysis software such as MSC. Nastran and Ls-Dyna. The FEA model of light truck cab is established and the loads and the boundary conditions are set up. Mode,stiffness,strength and crashworthiness characteristics of the cab are analyzed and evaluated systemically. Meanwhile,according to safety standard ECE R29,the model of the crashworthiness analysis of a light truck cab is established to perform the simulation of the positive pendulum impact test. The living space of the passengers in the cab is analyzed and evaluated,referring to alternating the relative data of the side of the driver. Simulation shows that the horizontal distance between the leg protection plate of the driver and the front end of the chair is bigger than the thickness of the thigh of the dummy model,which guarantees the space for the dummy model.
