摘要：

This study considers a solar array system as an example to explore the dynamic responses and wear characteristics of a multi-body system considering clearance joints with solid coating. A rigid-flexible coupling system is established based on the NCF-ANCF formulation, and the clearance joint model is established based on a novel contact law considering coating, a modified Coulomb's friction law, and Archard's wear law. The results of the deployment process dynamics of the solar array system with different coatings reveal the effects of coating, material, and coefficient of restitution on the impact properties of the rigid system and rigid-flexible coupling system. Meanwhile, the results of the attitude adjustment dynamics of the system with different coatings and clearance sizes reveal the effects of coating and material on the wear prediction of the rigid system and rigid-flexible coupling system. The effects of coating on the spacecraft attitude are also discussed. This exploration of the effects of solid lubrication of clearance joints on the dynamics of space deployable solar array systems is likely to guide practical engineering design for clarity and readability.
