摩托车底盘测功机阻力的设定

Setting the Resistance of Chassis Dynamometer for Motorcycle

摩托车工况法排放污染物测试及整车底盘动力性能测试都需要进行摩托车道路行驶阻力的测定及底盘测功机上摩托车行驶阻力的设定。利用惯性滑行法测定和计算摩托车道路行驶阻力,并进行底盘测功机上带车滑行试验调整行驶阻力系数,可以保证底盘测功机能够较精确地模拟摩托车实际道路行驶阻力。

Measurement of motorcycle emission by mode-test cycle and test of motorcycle chassis dynamic property should be conducted according to the measurement of the running resistance of motorcycle and the setting of motorcycle resistance on the chassis dynamometer. Measuring and calculating of running resistance by inertia coastdown method and adjusting of the running resistance coefficient by coastdown test with the vehicle running on the chassis dynamometer can ensure that the dynamometer shall accurately simulate the running resistance on real roads.
