Abstract
The subject invention provides a method of designing disc brake pads. The method includes the step of developing a finite element model of a precursor brake pad design using dimensional and material property information of its backing plate and friction pad to perform a normal mode analysis of the precursor brake pad design. The method proceeds with the step of performing the normal mode analysis using the finite element model to determine whether there is an area on the friction surface having an excitation amplitude that is greater than a threshold value of amplitude. If an area having an excitation amplitude greater than the threshold value is determined, the precursor brake pad design is modified to provide a brake pad design having a relieved portion in the area.
