مدل سازی لرزش و نویز در گیربکس: نسخه بلبرینگ – کامسول

This example is an extension of a model used to study the vibration and noise in a 5-speed synchromesh gearbox in a manual transmission vehicle. In this version of the model, a detailed representation of a roller bearing is used instead of hinge joints with elastic stiffness. First, the gearbox vibration is computed using a time dependent analysis for the specified engine speed and external load. A frequency domain representation of the normal acceleration of the gearbox housing is then computed to be used as a noise source. Finally, an acoustic analysis is performed to obtain the sound pressure levels in the near, far, and exterior fields.
