| Abstract: |
| The loading spectra of various road sections of satellite transport to launch site were measured based on the principle of current widely used rain flow counting method combined with Miner′ s rule. Pretreatment was carried out on the loading spectra using rain flow counting method. The application instance of analysis and evaluation on fatigue generated by the transport process based on Miner rule. A practical fatigue equivalent analysis method based on the acceleration signal spectrum loading for various transport conditions was put forward. The purpose was to provide reference for assessment of products withstanding mechanical environment and fatigue damage. |
