| Abstract: | With prototype technology, the fatigue load spectrum of rubber product for railway vehicle has been compiled. The random load of bushing can be calculated using the dynamic model of vehicle and counted in Rain flow way. The result of counting is distributing of mean and range of load. Grading the result, load spectrum can be established. |
