一、前言及符号说明拖拉机-挂车机组在运行中,受到道路不平度的随机性激励而产生随机性的响应,其数量规律可用概率和统计方法描述。通常用时域的均方值及均方根值描述随机振动的幅值特性和随机振动所消耗的
I. Preface and Symbol Description Tractor-trailer unit in operation, by the randomness of road roughness caused by the random response, the number of rules can be used to describe the probability and statistical methods. The mean square value and rms value of the time domain are usually used to describe the amplitude characteristics of stochastic vibration and the stochastic vibration
