Analysis Of Comfort Performance Of Train Based On Operation Simulation System

With the development of China Railway, the train is much lighter and the speed much higher, because of the influence of lightweight high-speed trains on the train comfort brings, it is becoming more and more apparent. People use less time to travel, but the train comfort put forward higher requirements. With the spurt of progress of city construction, the city rail transportation construction developed rapidly, it is very meaningful to improve the index of train operation and it is very meaningful to enhance the speed of train operation and comfort.With in-depth research, in order to reduce the research process in excessive spending and unnecessary waste of personnel, we use a train operation simulation system, according to the actual situation,the simulation system can stimulate the train operation, which greatly improves the work efficiency,and cost is also greatly reduced. In order to observe the relationship between the train during the train running speed and comfort, based on the the train operation simulation system, we make a study about train comfort.Train operation simulation system based on the IEEE1474.1train safe braking model as the prototype, the train running simulationis based on traction calculation, the train running state is detaily recorded, and the preservation as the offline files. When analyse the train state, you can use the offline data,and can finally get the analysis of train when the train run in different environments.In order to analyze the comfort of trains, a variety of waysto measurement learned made by previous scholars on the train comfort quality analysis, and ultimately selected UIC513as the train comfort evaluation standard. In the simulation system,I make the train comfort performance analysis module, the module can be calculated based on the original traction, which can measure and record the acceleration in three directions, analyzed and summarized analysis module for train comfort of train performance impact on performance, make the measurement and analysis of ride comfort of train operation simulation come ture.In order to improve the train comfort, I study on soft computing, eventually chose genetic algorithm as the tool to improve the comfort. In the genetic algorithm, we let train acceleration be chromosome, based on the selection, crossover, mutation operation, with the comfort of a train as the fitness function, the fitness evaluation of different acceleration, eventually get the acceleration value which has higher comfort value. Combined with the actual line data, we verify the optimization method of the analysis of comfort, and get the method of improving the comfort of train.
