Motion simulation technology in advanced design methodology for high-voltage switchgears is very important because of its performance in quantificationally analyzing kinematic and dynamic characteristics of the switchgears. This paper introduces some methods for constructing motion simulation models in UG_Motion environment, and discusses 3D collision and flexible motion simulation models in detail. Moreover, four real illustrative examples, i.e. contacts collision simulation, open-after-close analysis of spring operating mechanism, ratchet wheel walloping detent simulation for spring operating mechanism, and cracking simulation of a insulation link, are taken for demonstrating the feasibility and availability of the motion simulation technology. Conclusion can be drawn from these examples that the motion simulation technology can be applied to quantificationally kinematic and dynamic analyses for high-voltage switchgears.
