摘要
车辆防溜器是编组场尾部的关键设备。为了提高车辆编组的效率和安全性 ,需要对防溜器制动力的变化规律及其制动能高作深入的研究。运用力学中的三弯矩方程式和初始参数方程可以解决防溜器的超静定力学问题。计算表明 ,这种分析方法比起以前的静定分析方法所求得的制动能高要大。防溜器制动性能的研究也是编组场内车辆动态问题研究的基础之一 ,对建立编组场尾部数学模型有其应用价值。
Anti running device is important equipment in marshalling yard. In order to improve wagons' efficiency and security, profound researches on the regularity and braking energy height of the anti running device's movement are required. Super quiescent state problem of anti running device can be solved by applying 3 bend quadrature equation and elementary parameter equation. The method makes it clear that bigger values of braking energy height are got than those obtained by applying quiescent state analysis. Because the research on anti running device's property is also one of the wagons' dynamic problems in marshalling yard, it possesses important significance to establish mathematical model of the rear of marshalling yard. It is suggested that the practical value of friction coefficient should be taken according to various concrete statuses.
