基于变频技术的闭环汽车传动系统试验台的研究

The Closed-loop Automobile Driveline Test Rig Based on Frequency Conversion Technology

介绍了采用变频技术的汽车传动系统试验台系统结构和原理,阐述了变频器在汽车传动系统总成部件测试中的运用。通过变频器的组合使用,使驱动电机和负载电机实现电闭环。以自动变速器测试为实例,试验台能按照测试要求加载,并且能够进行能量反馈和再利用。

This paper introduces the structure and principle of the automobile driveline test rig, illuminates the application of converter in the test of assembly in automobile transmission system. With the combination of converters, it makes come true the closed-loop of the drive motor and load motor. Take the test of automatic transmission for instance, the motor could be loaded based on test requirement and part of the energy using in the test rig can be fed back and recycled.
