Outline
To establish a simulation model of the moving-iron electromagnetic actuator applied to automotive active tie rod mounts, a combined method of finite element electromagnetic simulation and bench test is adopted to conduct modeling simulation, performance calculation and test comparison analysis. A performance test platform for the electromagnetic actuator is built to obtain the test data of actuating force under different currents and frequencies. A simulation model of the actuator is established via electromagnetic simulation software to calculate the electromagnetic force output under corresponding working conditions, and the simulation results are compared with the test results for verification. The results show that the natural frequency of the electromagnetic actuator is about 30 Hz, and it outputs stably within the operating frequency range of 50~100 Hz. The actuating force amplitude presents a good linear relationship with the effective current value. The actuating force obtained by simulation is consistent with the excitation current in period, and the relative error between simulation and test results is controlled within 13%, which verifies the accuracy and reliability of the established model.
