“…The str ess at the junction of the lower shell edge and the boss where the threaded hole is located is the largest, and the maximum value is 0.30155Mpa, this is not the limit of 75 MPa material shells. Figure 6 shows that with the increase of the applied impact force, the deformation of the housing in the X-axis also increases [2], and 2 of the 3 sides of the housing have significant deformation, with the largest deformation on the left side and the smallest deformation on the right side.…”

The shell structure design of modern spacecraft internal devices is developing towards lightweight, high-performance, and low-cost. In order to achieve a lightweight construction of the shell structure, this work takes the spacecraft shell as an optimization object. Under the premise of ensuring that the stiffness of the box meets the design requirements, the lightweight construction of the box adopts a post-design optimization method. First, the preliminary design of the model was conducted using SolidWorks, and then the transient dynamic analysis of the model was conducted. The results met the design requirements. Then, the topology of the model is optimized using ANSYS Workbench software, and the optimization results are improved based on assembly conditions. Finally, a transient dynamic analysis of the topology optimized model was performed and compared with previous results. It was found that the design requirements were still met, while the weight was reduced by about 36.8%. This achieved lightweight design of the shell, improved performance, and reduced costs.
