Abstract:

Based on the multi-rigid body dynamic model of the circuit breaker contact system and mechanism system established by Creo and ADAMS,the reason for the bending deformation of the energy storage shaft in the actual experiment of the circuit breaker is analyzed by Ansys.Based on Hypermesh,Ansys and ADAMS,a rigid-flexible coupling model was established to make the lower link flexible and the contact system and other parts in the mechanism system rigid.The reasons for the fracture and failure of the lower link were analyzed through simulation calculation.Finally,through the calculation of two cases,it is indirectly proved that the results of multi-rigid calculation and rigid-flexible coupling analysis calculation by software have certain reference value,and also provide a basis for the solution of other similar problems in the subsequent product development process.
