摘要

根据温州市域动车组牵引系统设计的特点，提出了一种电动车组动力轴轮对轮径自动校验的控制方法。试验结果表明，该方法能准确校验电动车组各动力轴的轮径，辨识精度可以达到±0.5 mm。当校验到轮对轮径差过大时，能通过降低牵引电机功率或封锁牵引变流器脉冲的方式，保证动车组的安全可靠运行。

Abstract

According to the characteristics of the traction system design of Wenzhou urban EMUs, a control method of wheel diameter automatic inspection for EMUs power axles was proposed. The experimental results showed that the method could accurately inspect the wheel diameter of EMUs power axles with inspection accuracy up to ±0.5 mm. When the traction system inspected that the wheels diameter difference was too large, the power of motor or traction converter pulse would be limit, which ensured the safe and reliable operation of EMUs.
