Estimation of fatigue life on bolster spring of freight car in the load spectrum

货车枕簧在随机载荷作用下的疲劳寿命估算

Life Analysis on Bolster Spring Fatigue Test of Z_ ( 8A) Bogie

转（8A）型枕簧疲劳试验寿命分析

The result of this paper can be used validly when the fatigue performance of bolster spring is studied.

其结果可供深入研究枕簧的疲劳性能时参考。

Therefore, the quality and performance of bolster spring need to be safeguarded stringently, such as measuring and matching before being assembled.

因此，车枕弹簧的质量和性能需要有严格的保障，在使用前必须经过测量和选配后方能组装。

An automatic inspection and grouping of the bolster spring is realized with PLC as the control unit and linear encoder and rotary encoder as the measuring units.

用PLC作为控制单元，光栅尺、编码器作为测量元件，实现枕簧的自动检测与分组。

The bogie bolster springs bear all the load of freight car. The balance of spring-loaded in each group will directly affect operating life and traffic safety of the freight car.

铁道车辆转向架摇枕弹簧在运行中承受车辆全部载荷，各组弹簧承载是否平衡将直接影响其使用寿命和行车安全。
