Improving Finite Element Models of Brake Pads Through Material Optimization 2007-01-3946

A multi-dimensional constrained optimization method is presented to automatically adjust the elastic parameters of the friction material in order to minimize the discrepancy between finite element modal analysis and experimental modal testing. Application examples on semi-met, low-met and NAO materials show much improved results using the proposed method. Alternative material model that are not possible to use with the current commercially available ultrasonic measurement equipment, such as the orthotropic model, is also investigated.
