Analysis of Potential Shock Damage for Reed Contact Switch of Naval Ships' Electrical Equipment

  • 摘要: 对处于闭合状态的簧片式触点开关进行了接触模态分析,确定固有频率和振型;保证最大加速度响应、伪速度响应、最大位移响应中两者不变,设计不同正负双波时域冲击载荷,对簧片式触点开关进行有限元冲击模拟。动、静触头之间的接触力以及簧片根部应力在自由振动时呈现出周期性,接近一阶固有频率;最大加速度响应只影响触头间的接触压力,对于簧片的根部应力不能产生影响;伪速度响应只影响簧片根部的应力,而不能影响触头间的接触压力;最大位移响应的改变不能影响簧片的抗冲击性能。
