【摘要】 船用断路器是舰船电力系统中的重要基础器件，其在动力学冲击载荷作用下的性能将直接关系到整个舰船电力系统的安全。为了研究影响断路器抗冲击性能的因素，文中建立了断路器模型，运用动力学设计分析法（DDAM）和时域分析法进行仿真研究。针对结构强度不足的现象，进行了优化设计，并通过冲击试验来予以验证。所得结论和方法对进一步提高断路器抗冲击性能提供了参考。更多还原

【Abstract】 Marine circuit breaker is an essential basic device in power system of ship,and its performance under the dynamic shock load is directly related to the safety of the entire power system of the ship. For studying the factors affecting the shock resistance of circuit breaker,the circuit breaker model is set up in this paper,and the dynamics design analysis method(DDAM)and the time domain analysis method are used for simulation and study. The design is optimized for the insufficient structural strength and verified by the shock test. The conclusions and methods obtained provide references for further improving the shock resistance of the circuit breaker.更多还原
