摘要
在回顾高圆簧设计计算方法的基础上,推荐经试验验证计算精度较高的高圆簧垂向横向刚度、应力计算公式,进而讨论高圆簧的疲劳寿命计算。结合国内准高速机车高圆簧的寿命分析和疲劳试验。
Based on reviewing the design and computation methods of flexicoil springs,the formulas with higher computation accuracy demonstrated by tests for their vertical,lateral stiffness and stress are recommended;moreover,the computation of fatigue life of flexicoil springs is discussed.With the fatigue life analysis and test of the flexicoil spring for the Chinese quasi high speed locomotive,some suggestions are presented for the design and test of the secondary flexicoil spring suspension of the high speed locomotives and rolling stocks in China.
