Modelling and simulation for the vibration of a plate with three axes maneuvering

Abstract

Abstract In super-maneuvering flight, aircraft often bears high accelerations and high jerks. To ensure the safety of the aircraft, it is necessary to carry out the ground test to simulate the flight loads and the responses of the aircraft. In this paper, mechanical model of the accelerations are established, the distribution characteristic of the accelerations on the plate is explored and the consistency conditions for the centrifugal load and flight load are studied. The dynamic equations of a rectangular thin plate in three-axis centrifugal environment are established by Kane method, and the responses of the plate are calculated. The model established and the results obtained can be used to reflect the responses of the plate in the flight environment.
