【Abstract】 The three phase magnetic latching relay is established in Pro/E 3 D modeling software according to the actual size. By importing the model into the multi-body dynamic simulation software ADAMS and adding material properties,adding motion constraints to each part of the model,adding parameters such as magnetic chains and electromagnetic torque,the simulation model of virtual prototype is established. Then the dynamic simulation of the magnetic latching relay is carried out according to the simulation model,and the current change curve of the contact disconnection,closure process is obtained. The displacement and velocity characteristics of the armature and the three phase dynamic contact are analyzed in detail. Finally,the influence on the dynamic performance of the magnetically latching relay under different pulse voltage values and different pulse width values is analyzed. Then taking the optimal contact state of the contact as the goal,parametric modeling of stiffness coefficient of shrapnel and reed,and the best parameter combination of the relay is found,thus the optimization design is realized. It provides a powerful guarantee and basis for the development and optimization of magnetic latching relay.更多还原
