由机械系袁祖贻教授缪龙秀副教授等与力学所合作完成的“断裂理论在车辆结构零部件中的应用”和“大型车辆焊接结构的疲劳强度”已于6月8日通过校级评审.随着列车速度及载重量的提高,中、高强度钢在机车车辆零部件和焊接结构上的推广应用,断裂事故和裂损率明显增多,这说明传统的强度理论和设计规范,已不能满足设计要
The application of fracture theory in vehicle structural parts and the fatigue strength of welded structures of large vehicles, completed by Professor Yuan Zuoyi, associate professor Mu Longxiu, associate professor of Mechanics Yuan Zuyi, and mechanics, passed the university-level review on June 8. As the train The increase of speed and load, the popularization and application of medium and high strength steel on the parts and welding structure of rolling stock, the increase of fracture accident and crack loss remarkably, which shows that the traditional strength theory and design specification can not meet the needs of design
