摘要
本文根据在环行线进行C_(61)等运煤敞车及其变更方案动力学试验结果,对该型敞车发生脱轨的原因进行了分析。文中指出,该车的转8A型转向架减振系统的良好状态是保证其安全运行的关键。文中还指出,C_(61)型车的车体结构的某些参数不够合理,是导致其减振零件迅速磨耗的主要原因之一。文中根据以上分析提出了旨在保证运行安全的措施,同时也指出整个工作尚有不足,故分析仍应视为是初步的。
On the basis of dynamic test results of coalcar types C_(61) etc. with their variations on the test loop, factors causing derailment of C_(61) coalcars are analyzed. In this paper it is pointed that a good condition of the elements in the truck damping system is the key to ensuring safety running of C_(61) coalcar, and that improper selection of certain parameters of the body structure makes the damping elements easy to wear. In view of the above analysis some ameliorative measures are proposed in the paper.
