Abstract：To tackle the challnge of comprehensive analysis for the large-scale fast-locking mechanisms with tightly coupled multi-domain systems，a Modelica-based multi-domain modeling and simulation approach was proposed，focusing on the design and study of the mechanism’s structure，control and operating conditions. Firistly，the mechanism was partitioned into coherent submodules，for which a permanent magnet synchronous motor's electromagnetic model and the dynamics of the ball screw and push-rod assemblies were formulated.These component models were assembled into both subsystem and full-chain models within simulation platform. Secondly，the particle swarm optimization algorithm was used to optimize the control parameters of the drive system.Finall，three operating scenarios were evaluated— standard position control， fixed angular offset about the Z -axis，and dynamic three-axis angular offsets— to assess their influence on upright-positioning accuracy within a one-second setling time. Simulation results were validated against prototype experiments，demonstrating high positioning precision under all tested conditions. These findings confirm soundness of the mechanism’s design and the fidelity of the simulation models，and they ofer a methodological reference for the development of other large-scale，multidomain servo-controlled systems and their modeling-simulation approaches.
