基于SIMULINK的振动传递路径系统灵敏度分析

Analysis on Sensitivity of Random Vibration Transmission Path System Based on SIMULINK

基于一般概率摄动有限元法和结构系统响应的随机性分析理论,应用计算机仿真软件SIMULINK,以传递路径的传递率为度量指标,描述振动传递路径系统的路径传递率的排列顺序,并对振动传导路径系统进行灵敏度分析,得出路径阻尼的灵敏度大于路径刚度的结论。

Based on the general probability perturbation finite element method and the stochastic analysis theory of structural system response,the computer simulation software SIMULINK is used to describe the path transfer rate order of vibration transmission path system with the transfer rate of transfer path.Sensitivity analysis of the vibration conduction path system is carried out.The sensitivity of path damping is greater than the path stiffness.
