Fatigue analysis is one of common problems in domestic simulation field, because the stress level of the launcher's dangerous position can't be measured by the experiment. Compared with the calculation results and experimental results, based on the calculation results, the stress of dangerous sections was revised with the experiment in this paper. Furthermore, the RMS stress of the launcher's dangerous position and the fatigue life of the products were gotten.
Key words： fatigue strength; power spectral density; random response
