Simulation Research On The Vehicle Subsystem Of City Tram

With the urbanization and the expansion of the city,the urban traffic problem has become an archenemy to citizens.The appearance of the city tram provides a new kind of approach to solving the traffic congestion problem.It could be a great research direction for dealing with the traffic congestion problem.The thesis is based on the specialty of the railway signal,combined with the mature urban railway signal system,to come up with a feasible operation control system for the city tram.In this thesis,the functional requirements analysis and the detailed designs are also done for vehicle control system.Then,the single point motion model is built,which is based on the single point motion equation.Take the driving efficiency,the degree of comfort,the operation energy consumption,and the station dwelling error as the evaluation criteria,and combine with the model and the ACPSO algorithm,so as to optimize the control strategy.Finally,the function module of the vehicle control system is realized by using the C#language.Test the system to make sure the usability of the vehicle simulation system.The detailed research questions include the following aspects:In this thesis,both the background and significance are analyzed,and the systematic analysis of the operation control system is presented and designed.Business processes are analyzed according to the operation scene.The structure and the functions of the vehicle simulation system are brought in to divide the system into different functional modules.And then the thesis studies the key technology of the vehicle control system,which includes two parts.The first part is to build the motion model to do the train traction calculation,the other part is to optimize the control strategy to improve the driving efficiency,the degree of comfort,the operation energy consumption,and the station dwelling error which is based on the ACPSO algorithm.Eventually,the vehicle simulation system is realized and tested by the C#language to validate the usability of the system.
