齿轮传动系统在随机激励下的响应分析
Dynamic Response of Gear System with Time-varying under Random Excitation
摘要
Abstract
A four freedom degrees mathematical model of cylinder gear transmission system is built u-sing the lumped mass method,based on gear meshing theory and random vibration theory,but tooth surface friction is not considered.In this model,due to the stochastic parameters and random excita-tions,it has made the uncertainty system into stochastic system.A new model of the nonlinear gear system is established,aiming at the characteristics of random parameters in the system.So the dynam-ic response of gear transmission system with stochastic parameters and random excitations system has been researched and analyzed.And a simulation method which combines with MATLAB software is carried out to research the response of gear transmission system.关键词
