一种断路器多体动力学仿真方法
A New Method of Multibody Dynamics Simulation of Circuit Breakers
摘要
Abstract
A new method of multibody dynamics simulation of circuit breaker is developed based on continuous medium theory.By employing the elastic constitutive equation, the proposed model can be used to analyze the internal stress and strain related to different components of the breakers.The interaction between different parts and the energy transmission also can be studied by applying the linkage constraints to the corresponding boundaries.The proposed method not only can be used to predict the interrupting angular displacement and angular velocity, but also can be used to analyze the linkage and the relationship between the internal stress and strain of each component.Simulation results show that the maximum stress of each component changes over time.Experimental results show that the proposed simulation can be used to predict the interrupting characteristics of breaker with good accuracy.The new method offers a new design guidance to improve the mechanical reliability and the design of the breakers.关键词
