The invention discloses a target road spectrum obtaining method and system and a computer readable storage medium, and the method comprises the steps: obtaining a wheel center force of a wheel of a vehicle under selected excitation as a first wheel center force according to the selected excitation acting on the wheel of the vehicle; obtaining a wheel displacement transmissibility from the road surface to the wheel center according to the first wheel center force and the selected excitation spectrum; acquiring the wheel center force of the vehicle running on the target road as second wheel center force; and obtaining a target road spectrum according to the wheel displacement transmissibility and the second wheel center force. According to the method for obtaining the road spectrum of the target road, the first wheel center force of the vehicle under the selected excitation is obtained, the wheel displacement transmissibility from the road surface to the wheel center is obtained according to the first wheel center force and the selected excitation, and the second wheel center force when the vehicle runs on the target road is obtained; the target road spectrum is obtained according to the wheel displacement transmissibility and the second wheel center force. The obtaining method is low in cost, short in time and easy and convenient to operate.

    本发明公开了一种目标道路路谱的获取方法、获取系统及计算机可读存储介质,根据作用于车辆的车轮的选定激励,获取车辆的车轮在所述选定激励下的轮心力为第一轮心力;根据第一轮心力以及选定激励谱获得路面到轮心的车轮位移传递率;获取车辆在目标道路行驶时的轮心力为第二轮心力;根据车轮位移传递率和第二轮心力得到目标道路路谱。根据本发明实施例的目标道路路谱的获取方法,获取车辆在选定激励下的第一轮心力,根据第一轮心力以及选定激励获得路面到轮心的车轮位移传递率,获取车辆在目标道路行驶时的第二轮心力,根据车轮位移传递率和第二轮心力得到目标道路路谱,此获取方法成本低、时间短、操作简便。
