自动化驼峰间隔制动位短轻车控速程序改进

Improve Short and Light Carriages Speed Control Program of Automatic Humps in Spacing Braking Position

采用T.JK非重力式减速器作为调速工具的自动化驼峰,在间隔制动位对短轻车进行速度控制时,由于采用"闯口"式控制模式,容易造成低速出口。为此对速度控制方式提出了"适度放入"的改进方法,并在怀化南驼峰控制系统进行了实施,提高了系统对短轻车的控制精度。

The automatic humps adopting T·JK non-gravity retarder as speed control device take rushing speed control mode for rolling short and light car in the spacing braking position,which could cause low release speed.This paper gives an improved method with appropriate enter for speed control and a running trial has been carried out at the Huaihua South marshalling yard.The trial shows that the speed control system is more accurate for controlling the speed of the short and light car by this way.
