| 摘 要： | 推导了随机激励下，参数频变系统的统计线性化方法，利用该方法对铁牛654拖拉机非线性系统进行了平稳激励下随机响应的计算。讨论了轮胎和座椅减振器的非线性特性对拖拉机振动响应的影响，从而说明了把它们作为非线性元件来处理的必要性。

| Abstract: | The statistical linearization technique used to solve the system whose parameters are related to the frequency under the random excitation has been derived. As an application of this technique, the simulating computation for the response of Tieniu 654 nonlinear tractor has been made. The influences of the tire's and the seat shock absorber's nonlinear characteristics on the response of this tractor have been analysed, and the necessities of considering them us nonlinear elements proved. |
