Vibration Analysis on High Speed Disc of Submuniton Angular Motion Simulator

In order to analyze the vibration characteristics of the high speed dick system, which was an important component of the submuniton angular motion hardware-in-the-loop(HIL) simulation, the mechanics model was firstly derived. Then the stiffness and mass matrices of the high speed disc system were determined by means of the Lagrange's equations. To confirm the reliability of the presented theory, the results obtained from the equations were compared with simulating software-ANSYS. Finally, it was verified that the numerical results were identical with the simulating re sults. At the same time. the results demonstrated that the designed high speed disc system met the design requirements in the frequency domain.
