为弥补以往根据经验设计减速带的不足,建立了汽车通过减速带时的振动模型,利用状态空间法对系统的动力学响应进行求解;编制MATLAB程序对系统的加速度响应进行了数值计算,并分析了车速和减速带截面尺寸与最大振动加速度的关系.研究表明,汽车通过减速带时的振动加速度与减速带高度成线性正比关系;随着车速与减速带长度之比的增大,最大振动加速度具有先增大后减小的趋势.

In order to make up the deficiency of experiential for design speed control humps, the vibration model of vehicles passing over speed control humps is established, and the system dynamic responses axe solved by state space method. The system acceleration response is calculated numerically by editing MATLAB programs, and the factors which effect the maximum vibration acceleration are analyzed. The results indicate that the value of vibration acceleration is proportional linearly to the height of speed control hump, and with the ratio of speed and speed control hump length increasing, the maximum vibration acceleration is increased first and then decreased.
