Modeling Shoe-Lining Interface by CWELD Elements

A new technique utilizing Nastran CWELD elements to model the shoe-lining interface is proposed for brake pad finite element modeling. The method of constructing the interface model, including the location of each CWELD element, is presented. The proposed interface model is used to investigate the effects of end-lift on pad modal parameters. Applications of the interface model on simplifying brake pad and rotor meshes are also illustrated.
