基于Algor的万能式断路器操作机构的仿真与优化设计

摘要

With the help of Ansys finite element simulation analysis software, the short-term tolerance current value of air circuit breaker (ACB) was simulated, and the stress analysis and optimization design of the rotating shaft and cantilever of the operation mechanism of ACB were carried out by using Solidworks three-dimensional modeling software and finite element analysis software Algor, which meets the requirement of strong operation mechanism when short-term tolerance is broken.Based on the analysis of the tripping force of the mechanism, the tripping force is optimized through theoretical calculation and simulation analysis, and the reliability of the operation mechanism is improved.%借助于Ansys有限元仿真分析软件对万能式断路器的短时耐受电流值进行仿真, 利用SolidWorks三维建模软件和有限元分析软件Algor对万能式断路器的操作机构转轴、悬臂进行了应力分析和优化设计, 满足了断路器短时耐受电流下操作机构对强度的要求.在机构分闸脱扣力分析的基础上, 通过理论计算和仿真分析, 优化了分闸脱扣力, 提高了操作机构的可靠性.
