针对惯性姿态敏感器陀螺组件结构设计中出现的随机振动响应量级过大的问题进行分析研究.建立了陀螺组件结构的动力学模型,通过安装金属橡胶减振器并在结构中合理布置高阻尼比的阻尼材料综合解决陀螺头部振动响应过大的问题.对结构设计方案进行数值仿真和振动试验,结果表明,金属橡胶减振器和约束阻尼结构的应用能有效降低陀螺头部的高频响应,保证了陀螺仪在发射段环境条件下的可靠性.
In order to solve the problem that the random vibration response is too large, the dynamic model of the gyroscopic component structure is established. The metal vibration absorber is installed and the high damping Than the damping material to solve the gyroscope head vibration response is too large.Numerical simulation of the structural design and vibration test results show that the application of metal rubber shock absorber and restraint damping structure can effectively reduce the high frequency of the gyroscope head Response, to ensure the reliability of the gyroscope in the emission section of the environmental conditions.
