Analysis And Research On Bao-Lan Railway Of Freight Train Anti-Slip Test On Traction

Along with the development of high speed&overloading railway, the locomotive of the traction play also had higher requirements. But, traction play will be between the wheel and rail of adhesion restrictions, especially when a locomotive in wet on the rail operation, due to adhesion is reduced, very prone to idling, plus both domestic/straight type electric locomotives all adopt the correct type of air defense turn/the taxi control system, which can make poor road conditions in the mountains of railway transport process rainy day, the slow, stop slope wheel/rail scratches phenomenon particularly prominent.In order to improve the adhesion coefficient, usually by and sand method, but only rely on improving adhesion coefficient to turn air defense effect is not good. So, many researchers are devoted to improve the adhesion of locomotive the utilization ratio of the research, the purpose is in limited adhesion coefficient range possible to improve the adhesion utilization rate, make the system not only has the function of the air defense turn, also make the locomotive of as much as possible can play traction.This article through to the creep of the sliding theory analysis, in line with the principles of practical, the system was analyzed through ascension SS3B technology both after locomotives sticky control performance, whether can meet in simulation of rainy day12‰under the condition of the ramps stop start test, and according to the theoretical calculation and analysis and comparison of traction experiments, from technical Angle discussed in the line in both under the condition of science, and carry tons of safety and feasibility.
