The Optimized Research Of The Side Wall Deformation Control Of The Big Volume Wagon

Combined with the special purpose wagon developing direction and the market demand, to meet the transportation demand of the coal deep processing products of the coal-rich provinces, Shanxi, Neimeng, Ningxia, Xingjiang, The rolling stock company have developed, trial-produced and produced several coke special purpose open top wagon. As one type of the important railway special purpose wagon market, this open top wagon has filled the domestic market and has high technical content and important value.Combined with the requirement of developing heavy haul transportation and designing heavy haul freight wagon of the Ministry of railway, on the basic of the60t open top wagon, The rolling stock company researched and developed the big open top wagon, a new generation of heavy haul, large volume special purpose wagon. As a type of special structure open top wagon, it has drawn wide attention for its heavy haul, fast transporting circle. With the development of the market economy, this type wagon has huge potential market.Because the dimension of the wagon body is very big, the plate column side wall is tend to sidewise bending after be welded. The customers reflected that a certain number of the top of the side walls expanded outwards in the operating process.On the basis of analysis, for the purpose of reducing the side wall deformation, improving the deadweight, we further analyzed the structural design, welding process deformation control and optimized the process structure. Several design plans for controlling the side wall deformation were proposed, and one of the best was selected after comparing. By optimizing the process design and computer simulation analysis, the purpose of controlling the deformation was realized, and the customer satisfaction, loyalty were improved. The design optimization effect is very obvious. After comparing and analyzing the conclusion of the research topic of this project, this type wagon meets the relative design criteria, operational safety and the maintenance of this type wagon is very convenient.
