Traditional drive methods, however, often face challenges such as low deployment efficiency, poor control, and limited accuracy. To overcome these challenges and ensure effective use in space optical sensing, this paper proposes a new method for deploying and retracting telescopic arms using stepwise varying diameter surfaces during the deployment process. First, three basic configurations are proposed for different applications: fixed internal drive, following internal drive, and fixed external drive. Using tribology principles, the preloaded contact and friction transmission mechanism between the drive wheel and the step-formed surface is analyzed. An axial driving force model is developed, with optimized interstage transition parameters to reduce force fluctuations. Sensitivity analysis is performed to explore ways to increase axial driving force, and a virtual prototype is created for simulation verification. The results demonstrate that the driving force dynamics and kinematics models align with the simulation, effectively guiding the design of variable diameter drive mechanisms. Additionally, the study reveals that the maximum interstage transition angle influences peak deployment force fluctuations, while preload torque may hinder telescopic arm movement in certain cases Physical sciences/Engineering Physical sciences/Optics and photonics deployment mechanism telescopic arm variable diameter drive space optical remote sensor ultra-large aperture Full Text Additional Declarations No competing interests reported.
