A novel approach to determine upper tolerance limit of non-stationary vibrations during rocket launch

摘要：

　　This paper firstly introduces a locally stationary model to analyze non-stationary environmental vibrations during a rocket launch.Then based on this model, a novel method is proposed to estimate the upper tolerance limit of expected non-stationary environmental vibrations, which can be used to evaluate whether equipments on rocket can experience environmental vibrations in safe.Compared with available method, the proposed method can characterize non-stationary vibration better.
