Analysis on braking ability of automobile equipped with eddy current retarder

为掌握汽车上装用电涡流缓速器的制动性能及其对汽车制动性能的影响,建立装用缓速器的汽车制动时动力学方程式;结合道路试验,从下坡能力和平路上的减速能力两个方面考察电涡流缓速器的制动效能;通过道路试验,考察在中、高车速下,电涡流缓速器对汽车紧急制动的影响;从理论上分析了装用电涡流缓速器后,理想的汽车前。

The purpose of this study is to find out the braking ability and the change of the ability for the automobile equipped with the eddy current retarder. Firstly, the dynamic formulae of automobile equipped with the retarder are given. Then, the influence of retarder is studied when the automobile with high velocity is braked in emergency driving down slope and on the level road through road test. Finally, the change of the ideal curve of the braking force distribution between the front and rear wheels of the automobile equipped with retarder, and the braking stability in emergency are analyzed theoretically.
