Abstract
According to The Regulations on Loading and Securing of Railway Goods prevailing in China, the velocity will be limited when the center height of gravity for car loaded exceeds 2 m, which cannot meet the current demands of railway transportation. The sharp curve is an unsubstantial part in the rail. Thus, to reasonably work out the standard of the limited height of gravity center, the deep research of the process of vehicles running must be conducted on sharp curves. Based on the experiment and with the derailment coefficient, rate of wheel load reduction and lateral force of wheel axle as the safety assessment standard, the safety of C62HK -wagon loaded running on sharp curves after raising the limited height of gravity center is studied through statistical analysis of experimental data. At last, the safety technical requirements of C62BK Wagon, whose gravity center height is 2. 4 m, are put forward when running through sharp curves.关键词
