摘要
针对"汽车起动机电磁开关的端面结构不同"问题,在了解电磁开关基本原理的基础上,利用ANSYS有限元软件,比较分析了平顶型结构和锥顶型结构电磁开关的性能特点,并选择合适的端面结构和不同的结构尺寸变化进行了进一步分析。计算了平顶型铁心倒角长度和锥顶型铁心锥角的结构参数对电磁力的影响。实验结果验证了不同端面结构电磁开关的吸力特性,该结果对电磁开关设计具有指导意义。
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 calcu- lated. Experiment results verifies the attraction force characteristic of solenoid actuator with different end-structures. The conclusion is useful for follow research.
