我国驼峰调车场运营特点是:勾车组合复杂,车辆溜放基本阻力离散度大;货车车钩强度较小,货物装载加固标准不高,允许安全连挂速度低;货物列车编成辆数多,目的制动控制距离长;驼峰作业要求效率与安全并重,解体能力大,推峰速度高。因此,驼峰调车场车辆溜放速度自动控制难度大。自1974年以来,我国相继研制了减速顶、可控顶等调速设备,
The operation characteristics of hump shunting yard in our country are as follows: the combination of hook car and vehicle has large dispersion of basic drag; the strength of the car coupler is small, the standard of loading and reinforcement of goods is not high, and the speed of safety hooking is allowed to be low; The purpose of braking control distance is long; hump work requirements both efficiency and safety, disintegration capacity, push-high speed. Therefore, hump yard shunting vehicle speed automatic control difficult. Since 1974, China has developed a deceleration top, top control speed control equipment,
