摘要
船用塑壳断路器受冲击载荷作用后的冲击响应特性对船舶电力系统能否可靠运行起着重要作用。通过运用多体动力学仿真分析的方法,对塑壳断路器的操作机构进行抗冲击技术的研究,并对再扣板进行优化设计以满足抗冲击性能。通过运用刚柔耦合分析的方法,对具有双金属片保护的操作机构进行抗冲击分析,提出了在现有双金属片材料下需满足抗冲击要求的条件,并通过试验验证,可以为产品的抗冲击性能提供设计依据。
MCCB（ moulded case circuit breaker） impact response characteristic during impact loads is a critical concern for the reliable work of ship power system. The multi-body dynamics simulation method was used to study the impact resistance of MCCB,and the buckle plate to optimize the design to meet the impact resistance.The anti-impact analysis of the operating mechanism with bimetallic protection was carried out by the method of rigidflexible coupling analysis. The conditions of the impact resistance under the existing bimetallic material were put forward and verified by experiments,which can provide the design basis for the impact performance of the product.
