Study on Static and Dynamic Characteristics and Lightweight of Wireless Transmission Module Shell Structure
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.
