Abstract With virtual prototyping technology, this paper establishes the 3D virtual prototyping model of AC contactor including the whole contact system, core system and connecting parts. It reflects the real dynamic characteristics of AC contactor affected by the structure. Based on the finite method of continuum mechanics, the nonlinear contact, collision problem and elastic material deformation have been taken into account in the dynamic analysis software Ansys/LS-DYNA. Contact bounce in the process of contactor action is simulated. Moreover, by 3D visualization window, the displacement and velocity of movable contact and core changing over time are obtained and the dynamic characteristics of contactor are analyzed visually. In addition, the influence of closure speed, pre force of spring, properties of reed and friction coefficient of contact on contact bounce has been analyzed from the view of mechanical dynamics. The 3D virtual prototype design of AC contactor provides theoretical basis for its structure optimization design and has high practical value.

Key words： AC contactor 3D virtual prototype continuum mechanics bounce characteristics
