Research on Cycle Fluctuation of Flight Safety for Flight Materials Based on Spectral Analysis Method

摘要

To better master the development law of flight safety for flight materials, the spectral analysis method is introduced to analyze the cycle fluctuation of flight accident for flight materials. The basic principle of spectrum analysis of cycle fluctuation is first introduced, and then the calculation method of spectral density function is given. The actual example of flight accident shows that the method is an effective and feasible for analyzing the cycle fluctuation of flight accident. The research also has both theoretical and applicable value of flight safety management for flight materials.
