| Abstract: | The reactions of different counting method to the load sequence have been investigated by means of the load sequence generated by computer.The errors caused by the counting method in the fatigue life prediction for components have been analysed. The adapting principle of counting method to different load sequence has been pointed out. The conclusions of this paper are of great referential value for choosing correctly the counting method and for improving the predicting precision. |
