形貌优化是在材料成本不变的前提下提高结构刚度和强度的一种方法。简要介绍HyperWorks形貌优化计算流程,并以某型叉车机罩为例,利用Hypermesh建模工具和OptiStruct优化工具对其进行形貌优化设计。结果表明,形貌优化后的机罩刚度和强度相对原始设计方案有较大改进。这种设计思路大大减少了传统机罩设计中花费在不断改善加强筋布置上的设计时间,优化了设计流程。
Topology optimization is a method of increasing the stiffness and strength of a structure without changing the material cost. A brief introduction of HyperWorks topography optimization calculation process, and to a certain type of forklift hood as an example, using Hypermesh modeling tools and OptiStruct optimization tools for their morphology optimization design. The results show that the optimized stiffness and strength of the hood are improved compared with the original design. This design concept greatly reduces the design time spent in the traditional hood design to continuously improve the stiffener layout, optimizing the design process.
