为了满足不断增长的运输要求,开行重载列车势在必行。本文给出了对5000吨列车的纵向力试验结果。该试验列车由60辆C_(61)型敞车组成,由机车在前部牵引。试验结果说明:该型敞车能适应这种列车的运行;13号车钩的强度能满足多种工况的要求,但在某些非正常工况,如低速制动和低速缓解等,仍嫌不足;采用Mark50型缓冲器时,车钩力和纵向加速度均高于采用2号缓冲器。文中也讨论了试验中可能存在的问题。
In order to meet the growing transport requirements, the opening of heavy-duty trains is imperative. This paper gives the longitudinal force test results of 5,000 tons of trains. The test train consists of 60 C_ (61) gondolas towed by the locomotive at the front. The test result shows that this type of gondola can adapt to the operation of such train. The strength of coupler 13 can meet the requirements of various working conditions. However, in some abnormal conditions, such as low-speed braking and low-speed mitigation, it is not enough ; Using Mark50-type buffer, the hook force and longitudinal acceleration are higher than the No. 2 buffer. The article also discusses possible problems in the experiment.
