利用汽车垂直振动加速度判别路面等级的方法

Evaluation of Road Level Based on Vertical Vibrational Acceleration of vehicle

给出以汽车垂直振动加速度作为输入信号 ,路面不平度作为输出的数学模型及其模拟图 ,并依据道路分类标准做出利用路面的空间谱密度与空间频率的关系划分路面等级区域图 。

This paper gives a model and the simulating graph of road uneven degree, which is based on the vertical vibrational acceleration of the vehicle. The power spectrum has been analysed and the grade of the road can be evaluated according to the road grading standards.
