Abstract

Guided by the technical idea of modern data warehouse (ODS), focusing on the characteristics of unstructured big data of flight test data, facing the requirements of model engineering for unified management and efficient processing of flight test data, and aiming at the granular comprehensive management of flight test big data, it provides a basis for the establishment of on-line management and analysis system of flight test big data based on ODS and meets the requirements of model engineering for efficient analysis of flight test data. In order to test the stability of the landing gear system, the landing gear shimmy test was carried out on a real airplane for the first time in China. By installing an excitation board on the runway, the relevant modes of landing gear shimmy were effectively stimulated. The modal single peak isolation combined with the least square algorithm is used to analyze the experimental data through modal parameter identification. The results show that there is no shimmy in landing gear in flight test, and landing gear is stable in the test.
