摘要
针对汽车动力性检测时轮胎在双滚筒底盘测功机上的滚动阻力消耗功率问题,分析了双滚筒轮胎滚动阻力测试的原理,建立了轴荷、车速、胎压及双滚筒底盘测功机结构参数与滚动阻力的数学模型,应用一次回归正交试验方法L8(27),重新安排8次试验,用回归方程表达了轮胎滚动阻力。
According to existing problems of the wasting power caused by tire rolling resistance on dual roller chassis dynamometer in power capability testing,the principle of measuring tire rolling resistance which is tested on the dual roller was analyzed.The mathematic model of tire rolling resistance correlated with tire load,speed,pressure and structure parameters of dual roller chassis dynamometer was provided.Linear regression orthogonal experiment L8（27）was adopted,and 8 experiments were re-arranged.Regression equation was drawn to express tire rolling resistance.
