In order to improve the safety of the battery of satellite side mounting, and prevent the screw from producing excess due to frequent assembly and disassembly, the YS-20 material replacement and structure optimization design of the screw body are carried out under the premise of not changing the original tooling. The double-shear test of YS-20 bar is carried out, and the ANSYS optimization design module is used to design 7×7×6, a total of 294, calculation cases of D1, D2, T, the three important dimension parameters of screw structure. The actual bearing state of screw composite structure is accurately simulated by using asymmetric contact model. Three comprehensive evaluations are established, and the calculation examples satisfying the conditions are evaluated comprehensively. The final results are T=12.2 mm, D1=16 mm, D2=2 mm. The stress verification and contact analysis are carried out for the final scheme and the bearing state and contact state optimized screw structure are obtained.
