设备舱底板组件结构优化设计

Structural Optimization Design of Equipment Cabin Base Plate Assembly

为提高产品的性能,对设备舱底板组件进行静力学仿真。以底板组件的中间板厚和型材壁厚作为设计变量,构建设备舱底板组件3维模型,利用3维设计软件对底板组件结构进行参数化设计,基于轻量化原则,使用有限元分析软件对底板组件进行结构优化,对优化结果进行后处理,设置优化目标的参数与权重,确定最佳设计点。仿真结果表明:与原方案相比,优化后的底板组件质量减少40.94%。

In order to improve the performance of the product,a static simulation of the equipment cabin base plate assembly was carried out.Taking the middle plate thickness and profile wall thickness of the base plate assembly as design variables,the 3-dimensional model of the equipment base plate assembly was constructed,and the structure of the base plate assembly was parametrically designed using 3-dimensional design software.Based on the principle of lightweight,finite element analysis software was used to optimize the structure of the base plate assembly.Post-process the optimization results,the parameters and weights of the optimization target were set,and the optimal design point was determined.The simulation results show that the weight of the optimized base plate assembly was reduced by 40.94%compared with the original plan.
