- 摘要：
- In order to solve the problem of vibration bounce caused by the contact between moving and stationary contactsinthe process of switching on, two-degre-of-freedom mot on diferential equatron of the contact system is first established.GA(genetic agonithm) is used to optimize the pull in process of AC contactor The whole process of contact bounce wasobserved and analyzed by high-speed photography exp eriment. The theory and exp erimental results ac e very similar. The ironcore has collided before the contact has separated, whi ch further aggravates the contact bounce., When the iron core bouncescallided again, the bounce of the contact is not affected.During the operation of the contactor, the movement of the movingiron care will cause slight vibration of the syst em. The contact bounce time and the maximum amplitude are reduced. Theresearch results provide a theoretical basis for further control and reduction of contact bounce.
