Noise and Vibration Analysis of Petrol Engine Using Rubber Dampers

Abstract: This article presents the results of research into noise and vibrations produced by a petrol engine. The sound and vibration levels of the petrol engine were measured from the body frame setup. The engine rubber mounting technique have been chosen for the purpose of damping the vibrations and control body noise. The experiments were conducted to measure the noise and vibrations before and after putting the rubber dampers under the mounting of engine. Neoprene rubber mounts are used for the testing. Sound Level Meter and Accelerometer Sensors are used for the measurement of Noise and Vibration levels.
