转8A型枕簧随机载荷谱的分析确定

ANALYSIS AND DETERMINATION ON LOAD SPECTRUM OF ZHUAN 8A TYPE BOLSTER SPRING

通过建立转 8A型转向架摇枕与枕簧的力学关系模型 ,利用已知的摇枕实测载荷谱 ,分析确定出了枕簧的载荷谱。其结果可供深入研究枕簧的疲劳性能时参考。

The load spectrum of the bolster spring is determined by means of establishing the mechanics model of bolster and spring of Zhuan 8A type bogie, and by using a known load spectrum of the bolster. The result of this paper can be used validly when the fatigue performance of bolster spring is studied.
