Summary:

Concerning low frequency brake-squeal-noises of motorcycles, the noise caused by structural instability of the system was solved with the analysis of the mode-coupling mechanism by the complex eigenvalue analysis. An equation of motion of the brake system was simplified by converting from physical domains to modal domains. Required parameters for the stability analysis were obtained from the normal mode solution of system model. Moreover, the time for a repeat calculation in different friction coefficients and an instability-causes analysis in a mode were enabled to decrease 70% or more by using a numerical-analysis solver. An analysis model with high accuracy was established and was applied to the new approach, and to specify a mode affecting squeal noises and to study countermeasures were performed. From the test result for modified brake system, it was verified that the new method is effective for predictions and countermeasures of noises in the designing stage
