Abstract: Aiming at different endstructure of the solenoid actuator, the electromagnetic force of the solenoid actuator was analyzed using the finite element method(FEM) software ANSYS. The performance between the flattened structure and conetype structure was compared based on learning basic principles. The suitable endstructures and different sizeschanges were analyzed by selecting. The influence of structure parameters on electromagnetic force such as chamfer length of the flattened structure core and angle changes of conetype structure was calculated. Experiment results verifies the attraction force characteristic of solenoid actuator with different endstructures. The conclusion is useful for follow research.
