摘要
介绍了操作机构打开过程中的连杆转换现象。通过对比转换位置前后连杆的机械性能,研究了连杆转换位置对操作机构性能的影响。根据分析的结果,利用虚拟样机软件ADAMS计算了某塑壳断路器操作机构的最优连杆转换位置,达到了优化机构的目的。经过优化,使机构的打开时间缩短了1ms。通过对优化前后的机构进行实验对比,验证了仿真结果的可信性。分析结果可以为通过优化连杆转换位置提高机构性能提供方法和指导。
Linkage transfer phenomenon,which exists in the opening process of the operating mechanism of moulded case circuit breaker （MCCB）,is introduced. Influence of the linkage transfer position on the performance of the mechanism is analyzed. According to the analysis result,an optimum design is made for the linkage transfer position of a certain operating mechanism with virtual prototype software ADAMS. Simulation and experimental results show that after optimization the operating time of the mechanism is shortened about 1ms. The analysis result can provide guideline for improving performance of the mechanism by optimizing the linkage transfer position.
