The life monitoring of the landing gear structure plays an important role in ensuring its safety and economy. However, it is difficult to accurately predict the fatigue damage of the individual spectrum due to the complex high-low load interaction of the ground spectrum. Therefore, based on the equivalent damage calculation method, the paper analyzes the similarity between the individual spectrum and the reference spectrum by analyzing the individual spectrum in the life monitoring, and then analyzes the applicability of the damage calculation method. An approach for comparing the similarity of landing gear load spectrum based on dynamic time warping method in time series analysis is proposed, and fatigue test under the reference spectrum and 4 individual spectra is conducted. By analyzing the relationship between the damage calculation error and the similar distance of the landing gear load spectrum, the rationality of the load spectrum similarity discrimination approach is verified.
