| 中文摘要: |
| 基于道路减速带控速原理及传统减速带存在问题，分析了现阶段广泛使用的圆弧形减速带的车体垂向运动速度与加速度特性，提出了横截面两侧为两条余弦曲线的新型减速带的方案。从减速带截面的曲线方程为切入点，利用“数形结合”的方法重点对车轮与橡胶减速带整个碰撞过程中轮心的垂向速度和加速度进行分析。结合MATLAB等软件进行仿真，得出了余弦曲线橡胶减速带无速度突变的特性，对比圆弧形橡胶减速带的垂向加速度变化，该新型橡胶减速带对超速行驶的车辆有更好的惩戒作用，既能有效控速又能改善行车平顺性与乘坐舒适性，具有很好的应用前景。 |
| 英文摘要: |
| Based on the speed control principle of speed bump and the problem existed in traditional speed bump，the vertical velocity and acceleration characteristics of the vehicle crossing the circular arc-shaped speed bump which was widely used at present stage were compared，a new speed bump with two cosine curves on both sides of the cross section was proposed.From the curve equation of the deceleration section as the breakthrough point，accompanied with the method of calculation and modeling combination，the vertical velocity and acceleration characteristics of wheel center in the whole collision process of vehicle wheel and rubber speed bump was analysized.Simulated via the software of MATLAB，a conclusion was obtained that the rubber deceleration bump with cosine curve did not speed mutations，compared to vertical acceleration change of circular arc-shaped rubber speed bump，the new rubber speed bump had better disciplinary action for those traveling speeding vehicles，while it could effectively control speed and improve the driving and ride comfort，which had a good application prospects. |
