Abstract
One of the important issues in brake-squeal analyses using FE models is the reproducibility of the phenomena and the measures for minimizing natural-frequency differences between measurements and simulations for each of the components are crucial to the improvement of the reproducibility. In the evaluations of model-measurement correlations in the study of brake discs, if amounts of shifts in natural frequencies and their deviation orientation, between measured and simulated, varies in each vibration mode, the gaps in natural frequency cannot be adequately reduced by adjusting density and/or Young’s modulus. In this paper, we examine the effect of residual stress in motorcycle discs on natural frequency by X-ray stress measurement and simulation considering stress stiffening.
