摘要
为分析耐久底盘测功机的内阻大小与其使用时间、测试速度之间存在的相应关系,采用恒速阻力法对一款中置式耐久底盘测功机进行分时间段的多次内阻测量试验。得到随着使用时间的增加内阻值发生了一定规律变大的结果,分析得出不同速度区域的内阻改变量不同,不同时间段内阻的增加量也不一样,并根据试验数据得出以400h为分界点后新的内阻函数式F=(fν,t)。
In order to analyze the relations between the parasitic resistance of MACD and its using time or/and test speed, a resistance of compact MACD was tested by method of constant speed at different times. The results show the parasitic resistance is getting larger regularly with the time increasing. Results analyses show the change of resistance is different in various speed region and time area. Finally, the authors proposed a new resistance function, i.e., F=f（v,t） taking 400 hours as the dividing line.
