分析和研究货车车架,从车架的强度、刚度和自由模态入手,通过有限元进行仿真~([1])。文中不考虑车架的刚度分析和自由模态分析,只从强度分析展开研究,通过对比仿真结果,提出关于车架强度分析时的两点建议和在进行弯扭、扭转工况分析时的一种通过施加强制位移来代替以往施加力的加载约束方法,并验证其合理性。
The truck frame is analyzed and studied. Starting from the strength, stiffness and free mode of the frame, the simulation is carried out by finite element method ([1]). This paper does not consider the frame stiffness analysis and free modal analysis, only from the strength analysis to study, by comparing the simulation results, put forward two suggestions on the frame strength analysis and bending torsion, torsion condition analysis By applying forced displacement instead of the traditional method of loading constraint, and verify the rationality.
