Research On Automatic Train Disassemble System Of Hump Marshalling Station

With the rapid development of China’s economy and society,the railway freight volume is increasing day by day.As an important part of the railway freight process,the hump marshalling station’s working efficiency directly determines the railway transportation efficiency.At present,in the operation process of the hump marshalling station,only the peak uncoupling operation still needs manual participation,and the degree of informatization is low,which restricts the efficiency of railway freight transportation.In order to solve this contradiction,based on the analysis of the research results of the automation equipment of the hump marshalling station at home and abroad,a kind of automatic decomposition system of the hump marshalling station with high degree of automation information is designed,and the following work is carried out.1.A kind of three degree of freedom rectangular coordinate operating arm is designed.Based on Solid Works environment,a three-dimensional solid model of the end actuator gripper and operating arm is constructed,and the driving motors of the operating arm are checked based on the working load.According to the actual working situation,two different ways of uncoupling are discussed.2.A gripper structure of the end actuator holding the hook lifting bar is proposed,and a loading platform for carrying the operating arm and its auxiliary equipment is designed,and their working conditions are discussed respectively.3.The D-H parameter method is used to analyze the kinematics of the manipulator.The linkage coordinate system is established and the D-H parameters of the manipulator are analyzed.The kinematics equations of the manipulator are established and the forward and inverse solutions are studied.4.Based on the Lagrange function method,the dynamic equation of the manipulator is established,analyzed and calculated.The simplified Solid Works model of manipulator is imported into Adams for simulation.The simulation results further verify the correctness of the established dynamic equation.5.Design and discuss the separation function of system identification compartment,information processing and wireless communication module,train gap identification scheme of bearing platform and design of human-computer interface,which lay a theoretical foundation for the implementation of automatic train decomposition system in hump marshalling station.Based on the reality of railway transportation,the study can provide some reference for the hump marshalling station to realize operation automation and management information.
