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

M

otion 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 fr

om these examples that the motion simulation technology can be applied to quantificationally kinematic and dynamic analyses for high-voltage switchgears.
