| 中文摘要: |
| 测功机为内燃机试验的重要设备,用于测试其转矩及油耗.介绍了一种新型的交流电力测功机的构成方案,应用双馈式交流异步电机作为测功发电机,同时兼具电动起动及冷磨功用.通过测量电机的电磁功率及角速度来间接测算电机转矩.系统运用了单片微型模糊控制技术,使该新型测功机能自动运行,可大大提高劳动效率,从而有可能取代非自动的测功机并将得到广泛的应用. |
| 英文摘要: |
| This paper introduces a new project of AC dynamometer in which double electric feeding induction motor to be used as its dynamo electric machine. Before measuring,this new device can start the engine and can run in it without opening its oil supply. The method of measuring torque is indirect one by means of measuring the working parameters of the motor and then calculating its torque value. Because the advanced FUZZY control technique based on a single chip microcomputer system has been used to make the new dynamometer run automatically, the production efficiency can be prompted.It is possible that this kind of device will be widely used instead of the unautomatic ones. |
