Prestress modal analysis of the airplane wheel and brake

Abstract

In this paper, the structural integrated finite element model of aircraft wheel and brake device is established, the modal analysis of the wheel and brake device under prestress is carried out, and the vibration frequencies and modes of the first 12 steps of the wheel working are obtained through prestress modal analysis, based on the macroscopic mode shapes of each mode of the wheel, the influence of the mode shapes on the normal working state of the wheel braking device and the stability of the braking system are analyzed.
