Car Train Tracks Overlap Turned To The Study

With the rapid development of economy and improvement of the road conditions in our country, especially the successive completion of expressways, the auto-train transportation is oriented to the heavy-type and high speed. Therefore, it becomes an important subject matter of research to improve the mobility, safety and stability of the auto-train. Based on the analysis of the effects of the various steering-gears used in the auto-trains at present both in China and abroad on their steering mobility, this thesis chooses as its research target the full trailer of all-wheel steering, which has a better mobility, exploring the wheel trace coincidence of a steering auto-train. It mainly covers the following points:Presenting the concept of the wheel trace coincidence of a steering auto-train.Establishing the mathematical model for the wheel trace coincidence of thefull trailer of all-wheel steering.Analyzing the effects of various structural parameters on the wheel tracecoincidence of a steering full-trailer.Optimizing the design of the structure of the steering system in an auto-train;establishing the corresponding optimized design model.Developing the model which complies with the wheel trace coincidence of asteering full-trailer; performing simulating tests and errors analysis.
