| 摘 要： | 试验车速是汽车平顺性脉，中输入试验评价中的重要参数之一。根据汽车通过脉冲输入凸块时前后轮的振动响应互不影响的原理，利用速度的原始数学定义公式，提出的一种廉价而简单有效的试验车速计算模型，经误差分析，可得出其误差来源和影响因素。实车试验证明，该计算模型具有一定的合理性和有效性。

| Abstract: | The testing speed is one of important parameters in the automotive ride comfort test. Based on the principle of the vibration of the front-wheel has no influence on the vibration of the rear-wheel when the vehicle get across the hump, an effective and cheap model of the calculating speed has been put forward, which utilized mathematical definition of the speed. Moreover, the source of error and its in- fluence factors could be made sure by the error analysis. Finally, it can be showed by the test that this model is effective and reasonable. |
