摘要: 本文介绍了铁路驼峰自动化的车辆速度控制系统的方案概要及特点.提出用数理统计方 法,寻找车辆走行阻力在减速器工作前后的变化规律以及用回归线法预计车辆在编组线上的 走行阻力. 该系统在北京丰西编组站进行了运行试验,取得了预期的效果,实践证明它是一种简单、 经济、安全、可靠的溜放速度自动化制式.Abstract: A car speed control system of the automatic marshalling yard is described in this paper. The authous propose to search the varying laws of the rolling resistance in front and behind of the retarder by means of method of mathematical statistics as well as to estimate the rolling resistance of cars on marshalling track by the equation of linear regression. A trial run for the control system has been carried out at the Fengxi marshalling yard near Beijing and desired results have been achieved. Practice shows that it is a simple, economical, safe and reliabie automatic control system.
