Optimization Design Simulation on Stability Structure of Low Voltage Circuit Breaker

对低压断路器稳定性结构进行优化设计仿真,能够有效提高低压断路器工作稳定性。对低压断路器稳定性结构的优化设计准确性的研究,需要首先分析连杆机构,并构建其数学模型,对每一个连杆建立方程式,设计仿真过程迭代流程图。以加速度作为变量,分析系统刚体的受力情况,再根据牛顿第三定律,将拥有加速度的非惯性系转化到惯性系,对任意连杆机构优化设计准确性进行判断。通过优化设计和ADAMS仿真结果的对比分析,验证了优化设计模型的有效性和准确性,并在此基础上进一步改进和修正了仿真模型,最后用优化设计仿真模型对塑壳断路器进行了仿真分析,仿真结果证明,所提设计方法能够较好完成低压断路器的结构稳定性设计。

This article focuses on optimization design of stability structure of low - voltage circuit. Firstly, our research analyzed linkage mechanism and built mathematics model to establish equation for each linkage and design iteration flow chart, then analyzed force condition of rigid body of system using accelerated speed as variable. The research converted non -inertial system with accelerated speed into inertial system according to Newton＇s third law and judged veracity of optimization design of any linkage mechanism. Moreover, our research compared and analyzed optimization design and ADAMS simulation result to verify validity and veracity of optimization design model. On that basis, the research improved and amended simulation model. Finally, using the optimization design model, we completed the simulation analysis on plastic case circuit breaker. Simulation results show that the design method can complete design of the stability structure preferably.
