摘要	In order to enhance the spreading and retracting capability of the variable diameter internal drive device in the inter-stage transition phase of the space telescope deployable mechanism, this paper investigates the friction characteristics of the device at different moments during this phase based on the elastic Hertzian contact model. Firstly, the elastic contact state and friction type of the variable diameter internal drive device are analyzed at different moments during the transition stage. Next, a mechanical model is constructed to describe the relationship between the friction factor and radial preload in the inter-stage transition stage. Then, the force state in the inter-stage transition stage is analyzed using the finite element method. Finally, a test prototype is established to verify the elastic contact friction state of the variable diameter internal drive device during the inter-stage transition stage. The results indicate that the contact area between the radial preload and the elastic material of the variable diameter internal drive device has a significant impact on the friction characteristics during the inter-stage transition phase. Therefore, the friction factor at different moments during the inter-stage transition phase can be effectively adjusted by utilizing the radial load, thus enhancing the stability of the variable diameter internal drive device during the inter-stage transition.
