摘要
分析了火箭橇动态试验时振动频率宽、振动强度大的振动特性,建立了基础激励下双层减振模型,通过参数优化设计,设计了火箭橇双层减振系统。通过仿真计算和试验验证,双层减振系统可有效抑制火箭橇动态试验的高频振动,使橇车振动满足常见被试品工作环境要求。
The double free degree vibration damping system was designed to reduce response of vibration on tested product for vibration of rocket sled dynamic test which has width frequence and large intensity.Vibration characteristics of rocket sled dynamic test was analyzed and the double free degree vibration damping system was built with parameters optimization. Simulation calculation and experimental has verified that high frequency vibration could be effectively suppressed by the double free degree vibration damping system. Vibration of sled could meet the common test requirements of vibration environment after vibration damping.
