The working principle and structural characteristics of the new railway AX signal relay are described,and the mechanical counter-force calculation model of the contact system is established. A three-dimensional relay model is established via SolidWorks software, a new signal relay modeling and simulation based on Abaqus is proposed, and in-depth research is carried out on the unit type selection, grid division technology,boundary condition definition, complete machine modeling method and parameter setting in the finite element analysis of the relay. The operating and release motion process of the new signal relay is simulated via Abaqus to analyze the mechanical characteristic indicators of the relay. Through comparison of calculation, simulation and actual measurement, it is proved that the mechanical characteristics of the relay can be accurately analyzed with the modeling method, which can provide a basis for the design of new railway signal relay.
