【 摘 要 】

This paper makes use of the Stewart parallel mechanism acted as a parallel adjustment platform (PAP) on the satellite integrated assembly system, which is applied to carry on the adjustment of real-time high precision position and orientation for satellite integrated assembly. PAP's configuration optimization using optimization algorithm, which is designed to ensure the force on every limb in the workspace within the range of maximum value. The force of PAP's every limb is analyzed based on the screw theory, and is verified by the Adams software through simulation under the planning pathway, the result verifies the correctness of theoretical calculation. The research contents possess an important guideline significance for the structural design and performance optimization of PAP.
