Dynamometer Selecting Research on Performance Test Platform for Coal Mine Diesel Engine
Abstract：The load absorbers device of coal mine diesel engine adopts dynamometer. In order to improve drive performance of diesel engine, the principle, features and torque performance are introduced of hydraulic dynamometer, eddy current dynamometers, DC electric dynamometer and AC electric dynamometer. The advantages and disadvantages of these four kinds of dynamometer are compared. According to meet the requirments of diesel engine performance, DC electric dynamometer is selected as load device. The test shows that it could achieve good effect in full-speed range.
