摘　　要：舰用框架断路器受冲击载荷作用后的冲击响应特性对舰船电力系统能否可靠运作起着重要作用。本文建立舰用框架断路器冲击系统的数学模型,然后对冲击载荷作用下框架断路器进行了有限元建模和动力学仿真,分析了施加不同方向冲击载荷和施加不同大小冲击载荷时框架断路器机构的位移、加速度、应力历程、能量变化等动态响应特性,探讨了研究舰用框架断路器机构冲击响应的新思路和方法。最后,对舰用框架断路器抗冲击设计提出了一些建议。ACB （Air Circuit Breaker） impact response characteristic during impact loads is a critical concern for the reliable work of naval ship power system. Instead of impact test method, a new approach is discussed in this paper, which built the mathematics model and created a finite 3-D element model of ACB firstly, and then made the dynamics simulation for ACB impact model. According to this, impact responses of ACB, such as displacement, acceleration, strains, and energy, are analyzed respectively under different impact mass values and directions. Finally, the paper presents some useful suggestion for the anti-impact design of ship used ACB.
