铁路货车在运行中启动、加速、减速、制动,或进行编组作业时,以及事故发生时车列、车辆之间出现正面冲突等情况,都会对货车车辆产生巨大的纵向冲击力。当冲击的剧烈程度超过了车辆材质结构所能承受的屈服极限时,就会造成铁路货车的损坏。其中最为常见的就是从板座铆钉折断故障。本文针对车辆从板座铆钉切断的原因、分布情况及检查方法展开分析。
When a freight wagon starts, accelerates, decelerates, brakes, or performs a grouping operation during operation, and when there is a positive collision between the train and the vehicle at the time of the accident, the railway wagon will have a huge vertical impact on the wagon vehicle. When the intensity of the impact exceeds the yield limit that the vehicle’s material structure can withstand, it will cause damage to the railway wagon. One of the most common is the rivets from the board break off the fault. This article analyzes the reasons, the distribution and the inspection methods of the rivets cut off from the plate seat.
