A mathematical model is proposed to illustrate the frequency characteristics of roller bearing vibrations due to surface irregularities which come from manufacturing errors. The bearing vibration is modeled as the system output when it is subjected to the excitations from surface waviness and surfac

Propagation of periodic waves in the vicinity of irregular saw-tooth shaped boundaries in finite difference models is investigated. The reflection of an incoming wave from a single saw-tooth boundary is found to be accompanied by a phase shift. It is shown that any wave mode propagating along such a
