摘要
矿用柴油机性能试验台以测功机为加载吸功设备,为提高矿用柴油机的动力性能,介绍了水力测功机,电涡流测功机,直流电力测功机,交流电力测功机的原理、特点和扭矩特性,并分析了四种测功机的优缺点。根据矿用柴油机特性选用直流测功机作为加载设备,通过试验验证,选用直流测功机在全速度范围内可以达到较好的效果。
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.
