刚性构架货车转向架能适应高速运行,不会使线路或货物产生过大应力。1960年以后,这种转向架已成为欧洲标准转向架,并在实际运用中得到了满意的结果。由于刚性构架出现某些疲劳损伤,1974年又重新进行了设计。本文叙述了该型转向架的缺陷及其解决方法,并详尽地介绍了新转向架在实验室和实际运用中的试验结果。 Rigid frame truck bogies can adapt to high-speed operation, will not make the line or goods have too much stress. After 1960, the bogie has become the European standard bogie and has been satisfactorily achieved in practical application. Due to some fatigue damage to the rigid frame, the design was re-planned in 1974. This article describes the defects of this type of bogie and its solution, and introduces in detail the test results of the new bogie in the laboratory and its practical application.
