COMPUTER SIMULATION OF THE DYNAMIC AND VIBRATION RESPONSE OF A BELT DRIVE PULLEY

Torque transmitted from rim to the shaft through the arms of the pulley is analyzed in this paper. Dynamic and vibration response of the arm of the pulley of a belt drive is studied by transferring the system to equivalent spring, mass and damper system. The number of arms present in the load zone is assumed to take charge of the load zone angle equally as they appear in the load zone. Hence, the arms are subjected to stepped load wave. The arm is considered as a tapered cantilever beam fixed at the hub and stepped loading at the rim end. Response of this equivalent system is studied by varying equivalent damping coefficient from 0 to 5·0. This investigation aims at getting a cursory idea of the maximum stress due to vibration. tural frequency of equivalent system is compared with that of tapered cantilever beam to check its accuracy.
