我国对于减速顶调速技术的研究已经整整十个年头了。回顾我国减速顶诞生和发展的历史,是一部实事求是地探索解决我国铁路编组场调速技术问题的历史。1974年哈尔滨站下行场试验应用三个部位减速器进行目的制动控制,由于坡度较陡、车辆走行阻力离散度大以及冬夏温差大等原因,未能取得理想的效果,于是,为了因地制宜、实事求是地解决这个老站场的目的制动控制问题,才开始了减速顶的研制。自从1977
Our research on the technology of decelerating top speed has been a full ten years. Reviewing the history of the birth and development of China’s deceleration top is a history of exploring and solving the technical problems governing speed governing the country’s railway marshalling yard in a down-to-earth manner. In 1974, the test of Harbin Railway Station in the down field was carried out with three parts decelerator for the purpose of braking control. Due to the steep gradient, the large dispersion of running resistance of the vehicle and the large temperature difference between winter and summer, the desired effect was not achieved. Therefore, in order to adapt to local conditions and seek truth from facts To solve the purpose of this old station brake control problems, began the development of deceleration top. Since 1977
