?A Study of the Two Wheeler Retarder Type Dynamometer System?

Nilesh R. Mate, Prof. D. Y. Dhande

In this study a compact system carrying the eddy current retarder used for the testing of two wheel vehicles is designed. A braking torque of the eddy current retarder is 400 N-m at a speed of 1200 rpm. According to the characteristics of the eddy current retarder, an exclusive test bed was developed and used for brake performance measurements. The main technical parameters, such as the brake characteristics, temperature characteristics and power consumption, were measured with the test bed. Major focus area in this paper is for study of brake characteristics. By observing the torque v/s rpm curve the torque increases initially and reached maximum value at rated or design condition and then torque starts decreasing as rpm increases further. A roller is provided at rear wheel of vehicle and front wheel is properly restrained in clamps to avoid the movement of vehicle.
