| Abstract: | 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. |

| Keywords: | bogie alter-rigidity spring combinations fatigue intensity life |
