Numerical Simulation of Vehicle Vibration Response on Complex Road Surface Based on ADAMS

摘要: 随着我国社会经济的快速发展以及人们的生活水平的不断提升，人们对汽车的持有量也在不断增加。脉冲路面如减速带、减速桩等作为车辆在驾驶过程中十分常见的路面，对其进行动力学仿真十分必要。本文通过对简单四轮汽车模型在不同减速带地面模型下的振动进行分析得到了路面模型、车速以及车辆自身阻尼对车辆振动幅度的影响，并得到了其通过崎岖路面的振动幅度对比。

Abstract: With the rapid development of China’s social economy and the improvement of people’s living standard, people’s ownership of cars is also increasing. Impulsive road surfaces such as speed bumps and speed piles are very common as vehicles in the driving process, and it is necessary to simulate their dynamics. In this paper, the vibration of a simple four-wheeled vehicle model under different speed bump ground models is analyzed to get the effect of road model, vehicle speed and vehicle’s own damping on the vibration amplitude of the vehicle, and the comparison of its vibration amplitude through the rugged road surface is obtained.
