基于齿轮啮合原理及随机振动理论，在不考虑齿面摩擦的情况下，采用集中质量法，建立直齿圆柱齿轮传动系统4自由度的简化模型。在该模型中，由于参数的随机扰动和随机激励的存在，使得确定性的系统变为随机系统。针对系统中随机参数作用的特点，建立新的齿轮系统非线性模型，研究随机参数下齿轮传动系统的响应和随机外激励下系统的响应，并结合MATLAB软件对齿轮传动系统的响应进行了仿真分析。

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.
