摘　　要：运用随机理论，综合道路状况、车辆特性、结构参数及行驶速度等因素，给出了双轴四轮车辆隔振系统的动态特性和道路谱矩阵．推得车辆垂向振动、横向摆动、纵向颠簸的位移、加速度响应谱和均方值的一般公式．The matrixes of road spectrum and the frequency response characteristics of vibration isolation system of double axle and four-coupled vehicles are established according torandom theory as well as considering those comprehensive factors such as road condition, vehicle dimension and moving speed, structure indexes, and so on. A general formula of thepower spectral density and square mean value of displacement and acceleration of the vertical, lateral, longitudinal vibrations of double axle vehicles are also developed.
