敞车占我国货车保有量的61%,其中钢木混合结构敞车已经停止生产,并在逐步淘汰和减少,全钢敞车的比重逐年增加。合理确定全钢敞车的使用寿命和检修周期对于铁路运输和车辆修造工业具有重要的意义。

The proportion of all-steel gondola cars has been increasing year by year. Reasonably determine the service life and maintenance cycle of all-steel gondola is of great significance to railway transportation and vehicle repair industry.
