1.前言最近,随着电子设备的发展,机车节能化不断推向前进。在这样的趋势中,防止机车空转、最大限度地利用车轮踏面粘着系数,提高机车牵引能力,是其中重要的一环。以往的空转检测,是采用比较牵引电动机的电压,电流和转速的办法,由于检测速度迟缓,再粘着控制还未生效,机车已经产生急剧空转了。这里研究的防滑控制系统,既允许有微小的空转,又能获得最大的粘着系数利用。它的原理是采用扭矩传感器检测出空转前动轴的扭转振动,根据这个振动的大小,控制加于牵引电动机的电量。在这种控制系统中,开发了可以
1. Introduction Recently, with the development of electronic equipment, the locomotive energy conservation has been continuously pushed forward. In such a trend, it is an important part to prevent locomotives from idling, to make maximum use of the wheel tread adhesion coefficient and to improve locomotive traction capacity. In the past, idling detection was based on the comparison of the voltage, current and speed of the traction motor. Since the detection speed was slow and the re-adhesion control was not effective yet, the locomotive had produced a rapid idling. The anti-skid control system studied here allows both a slight idling and maximized utilization of the cohesion factor. Its principle is to use a torque sensor to detect the torsional vibration of the rotating shaft before idling, and control the amount of power applied to the traction motor according to the magnitude of this vibration. Developed in this control system
