Abstract
The subject invention provides for disc brake pads and a method of designing disc brake pads. The brake pads include a backing plate and a friction pad having a center section, an outer edge, an inner edge and a friction surface. The method includes the step of developing a finite element model of a precursor brake pad design using dimensional and material property information of the 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.
