Research on design of coupling section in hump Shunting Yard
摘要
Abstract
Design of coupling section in hump Shunting Yard not only decides rolling condition of car, such as o-ver -speed coupling and skylight, but also affects shunting operating efficiency, ability and safety on hump. In view of problems existed in coupling section design at present, taking three factors, i. e. , maximizing rolling length of hard running car , minimizing numbers of pony retarder and minimizing difference - value between optimal height and calculated height, as the objectives, a multi - objective optimization model of three slope design of coupling section was established. Considering the discrete combinatorial optimization characteristics of the model, the set of grade combination schemes was determined firstly, and then the optimal solution was obtained by comparing the candidate schemes. The reasonable grade combination scheme and the best length proportion relation were obtained by calculating and analyzing the objective function of each given scheme. On basis of the existing Hump Design Code (HDC) , the result can be taken as a theory method to practical design.关键词
