| 摘 要： | 基于实车道路滑行试验数据，采用两段滑行试验法计算汽车的滚动阻力系数和空气阻力系数。通过在相同条件下车辆的低速滑行试验数据计算所得系数对上述计算结果进行初步判定，证明了两段法计算结果的合理性。采用多车速滑行试验法和功率法对两段法计算结果进行验证，证明了采用两段滑行试验法计算汽车滚动阻力系数和空气阻力系数的正确性。 |

| Abstract: | Based on the vehicle coast-down test data,the rolling resistance coefficient and air resistance coefficient were calculated by using the two-stage coast-down test method.The low-speed coasting-own test under the same conditions was applied to identifying the calculation results.The results show that the calculation method is reasonable.Then,multi-ample coasting-own data and power calculation method were applied to verifying the results.The results show that the two-stage coast-down test method is correct an... |
