Abstract :
Based on the complex modal analysis technique, the finite element models of the disk brake system and its components are established, the ABAQUS/Standard solver is used to calculate the complex eigenvalue of all modals under different friction coefficients. The results show that the number of the instable modes and the real part of the complex eigenvalue increase gradually with the increase of friction coefficient, Further analysis in modal coupling demonstrates that if two adjacent modals´ frequencies coincide and the signs of their complex eigenvalues´ real parts are opposite, the modal is an instable modal and produces brake noise.
