摘要
以多体系统动力学为基础,建立低压直流断路器的动力学模型。将机械运动方程和电路、电磁场方程耦合求解,从而实现考虑电动斥力的断路器分断过程仿真。通过有限元分析软件Ansys与多体动力学分析软件ADAMS的协同仿真,建立断路器的刚柔耦合动力学模型,完成关键零件在断路器短路故障分断过程中的强度分析,为断路器设计中关键零件的设计和优化提供一条有效的途径。
A dynamic model of DC low vohage circuit breaker was established on the basis of the dynamics of muhi-body system. Coupling the motion equations and the circuit equations with the magnetic field equations, the breaking process of the circuit breaker considering electrodyuamic force was simulated. A rigid-flexible coupling moulded case circuit breaker simulation moulded was developed by use of the software ADAMS for multi-body dynamics and Ansys for finite element analysis, and the stress distributing characteristics in the key parts of the model for the breaking process were analyzed. The approach proposed will provide a method for the design and optimization of the key parts.
