基于HyperWorks的轻型电动物流车车厢骨架结构分析及优化设计

Structure Analysis and Optimization of Light Electric Logistics Carriage Frame Based on HyperWorks

以某电动物流车车厢骨架为研究对象,利用HyperMesh软件建立了该电动物流车车厢骨架的力学有限元模型,对满载状态下的车厢在弯曲、转弯、制动及扭转4种工况下进行了有限元分析,以该电动物流车车厢骨架厚度作为设计变量,对车厢骨架进行了优化,确保优化结构的合理性,实现了车厢轻量化设计目标。

Taking the carriage frame of an electric logistics vehicle as the research object,the mechanical finite element model of the carriage frame of the electric logistics vehicle is established using HyperMesh software,and the carriage under full load is carried out under four working conditions:bending,turning,braking and torsion.The finite element analysis used the thickness of the carriage frame of the electric logistics vehicle as a design variable to optimize the carriage frame to ensure the rationality of the optimized structure and achieve the lightweight design target of the carriage.
