Digital collaborative exploration and practice of ground vibration test for full-scale aircraft

Abstract

The ground vibration test of full-scale aircraft has the characteristics of multiple coordination units, complex system, long implementation time and high risk. Facing the need of efficient development of advance aircraft, it is necessary to improve the capability of the test by introducing the digital means. In this paper, the flow of ground vibration test in traditional mode is summarized, the elements of digital test are analyzed, and the digital test programme is constructed preliminarily. It is pointed that the current digital collaboration model has significant benefits in reducing experimental risks and improving experimental efficiency. In the future, it is necessary to further promote the integration of digital and real simulation and application platform development to promote the mature implementation of digitalization.
