摩托车道路行驶阻力分析与测量

An Analysis and Measurement of Road Running Resistance of Motorcycle

分析了摩托车道路行驶阻力的数学模型,并在天津摩托车技术中心试验场对某125型摩托车采用滑行能量法进行了滑行参数测量。用最小二乘法拟合出摩托车的行驶阻力曲线,并将该曲线在不同速度下的阻力数值与当量惯量法的阻力数值进行了比较,二者达到了很好的统一。

The paper analyses the mathematical model for road running resistance of motorcycle, and the coasting parameters of 125 type motorcycle are measured by means of the coasting energy method at the proving ground of Tianjin Motorcycle Technical Center. The running resistance curve of the motorcycle is obtained by means of the least square method and a comparison between the resistance value of the curve at different speeds and that gained according to the equivalent inertia method is made. And it is found that the two is extremely uniform.
