ABSTRACT:
A method, apparatus, and program for estimating noise generation for a synchronous belt having a length and teeth spaced along the belt length. The method includes the steps of: calculating belt displacement transversely to the belt length at or near a first location at which teeth on the belt mesh with teeth on a first cooperating toothed pulley; calculating a belt fluctuation velocity by correlating the belt displacement to a time frame; and calculating a radiated sound pressure level using the belt fluctuation velocity.
