摘　　要：针对航天飞行器无线传输模块壳体结构的轻量化问题,利用UG/NX和ANSYS Workbench软件构建了壳体结构的计算机辅助设计模型,并通过静力学特性和模态特性分析,对其性能进行了评估。以总体质量最小化为优化目标,将轴向壳体厚度、径向壳体厚度、周向壳体厚度三个参数设为设计变量,并采用多目标优化方法对壳体结构进行了优化设计。研究结果显示,经过多目标优化设计后,最大变形量和最大等效应力分别增加了0.0001 mm和0.002 MPa,不会对壳体结构性能产生显著影响。而壳体结构的总体质量则减少了31.77%,这一成果显著降低了无线传输模块的发射成本,降幅高达13.6%。这一研究成果为航天无线传输模块壳体的优化设计提供了重要的参考依据,为推动我国航天事业的发展做出了积极贡献。Aiming at the lightweight problem of the shell structure of the wireless transmission module of aerospace vehicle,a computer-aided design model of the shell structure was constructed by using UG/NX and ANSYS Workbench software,and its performance was evaluated through the analysis of static and modal characteristics.Taking the minimum mass as the optimization objective,the three parameters of axial shell thickness,radial shell thickness and circumferential shell thickness were set as design variables,and the shell structure was optimized by multi-objective optimization method.The results show that the maximum deformation and the maximum equivalent stress are increased by 0.0001 mm and 0.002 MPa respectively after the multi-objective optimization design,which will not have a significant impact on the structural performance of the shell.The overall mass of the shell structure is reduced by 31.77%,which significantly reduces the transmission cost of the wireless transmission module by 13.6%.This research result provides an important reference for optimal design of space radio transmission module shell,and makes positive contribution to the development of space industry in our country.
