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。
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. 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。
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。
