Compared with the traditional docking mechanism, a low-impact mechanism (LIDM) has big advantage, that is, LIDMs can realize by controlling movement of driving rods in real-time. In this process, load sensing ring (LSR) chaser spacecraft is adjusted real-time according to position and attitude target spacecraft, which requires LIDM high transmission efficiency, so LSR be changed rapidly under motion respond requirements control system as soon possible. paper, efficiency solution an optimization method suitable for are proposed. The dynamic model established, improved genetic algorithm better convergence effect proposed used optimize transfer efficiency. results numerical examples paper show stronger global ability when calculating high-complexity problems. optimized configuration parameters, size bottom reference circle close lower limit upper given limit, respectively, instantaneous force ratio increased from 0.6477 0.9160. reliability verified simulation software. This study provides ideas methods design subsequent mechanisms.
