基于HyperWorks的卡车车身结构拓扑优化设计

Research on Topology Optimization Design of Truck Frame based on HyperWorks

以数学规划为基础,使材料在设计空间中得到最优的分布和形状,为设计者提供设计思路,能够缩短新产品的设计时间。利用变密度法,对卡车车架进行拓扑优化设计,不但满足了设计要求,而且为此类超静定结构的设计提供了思路。

Topology optimization is a design method based on mathematical programming to seek an optimum distribution of material,greatly shortened product conceptual design cycle with the help of variable-density method,topology optimization was carried out for heavy-duty truck frame based on HyperWorks platform.The way not only satisfied the design requirements,but also provided reference for the new product design.It provides an important technical message for conceptual design.
