摘　　要：对转K6型变刚度弹簧组的疲劳强度进行了理论分析,利用名义应力法对疲劳寿命进行了估算,利用考虑实际重车载荷下的“当量挠度法”对疲劳强度进行了校核,同时进行疲劳试验对理论分析进行了验证.Based on general method, fatigue life for the alter-rigidity spring combinations of Type K6 bogie is estimated. Making use of the ＂equivalent flexibility method＂ which considers the actual operating conditions, the fatigue intensity of this new type of alter-rigidity spring combinations is confirmed. At the same time, the theory analysis is vertified by fatigue test.
