摘　　要：为了使车辆在转鼓试验台上的制动过程与路试的制动过程尽可能一致,需要估算的等效转动惯量尽量接近真实值。考虑了制动过程中车辆的轴荷前移及转动半径的选取,提出了一种等效转动惯量的估算方法。该方法针对车辆制动时前轴等效惯量的计算,使用在车辆的单轴转鼓实验中,适用于电动汽车制动能量回收过程的研究。通过台架实验与实车路试结果进行对比,证明了该方法的有效性。In order to make the vehicles＇ braking process on Chassis Dynamometer platform as far as possible consistent with that on the road, the estimation of equivalent rotational inertia was required to be as far as possible close to the true value. Considering redistribution of vehicle axle load in the braking process and selection of turning radius, a method for estimating equivalent rotational inertia was put forward. The proposed method was used for the calculation of front axle equivalent inertia and used for two wheel drum experiment, which was suitable for the analysis on electric vehicle braking energy recovery process, Through the comparison of results of bench experiment and real vehicle road test, the results prove the validity of the proposed method.
