本文讨论了在频域对车辆响应进行数值分析的一种可能性。它适用于四分之一型号的车辆。对于选定的车辆计算模型，量化了力量和运动学量的频响函数。它考虑随机道路轮廓。道路轮廓的功率谱密度（PSD）作为输入值，用于计算响应的功率谱密度。在程序系统MATLAB环境下进行了数值计算。当我们知道频响因子的模块或车辆模型的功率响应因子（PRF）时，在频域上计算车辆响应是快速有效的。
The offered article deals with one of the possibilities of numerical analysis of the vehicle response in frequency domain. It works with quarter model of vehicle. For the selected computational model of vehicle it quantifies the Frequency Response Functions (FRF) of both force and kinematic quantities. It considers the stochastic road profile. The Power Spectral Density (PSD) of the road profile is used as input value for the calculation of Power Spectral Density of the response. Al calculations are carried out numerically in the environment of program system MATLAB. When we know the modules of FRF or the Power Response Factors (PRF) of vehicle model the calculation of vehicle response in frequency domain is fast and efficient.
