Experimental Study of Cabin and Engine Mounts and Their Effects on Cabin Noise Pressure
Independent thesis Advanced level (degree of Master (One Year)), 60 credits / 90 HE creditsStudent thesis
This project investigates engine and cabin mounts of articulated haulers. Experimental study of engine and
cabin mounts identifies the structural behaviour of the complicated metal-net elastomeric mounts to isolate
driver from noise and vibration transfer. In order to achieve the expected results, the loss factor and dynamic
stiffness of engine mount is studied to provide fundamental information of the energy dissipation.
A simple experimental method is presented in this project to evaluate the frequency dependent rubber mount
stiffness and damping characteristics by utilizing the measured complex frequency response function from low
frequency. The study shows the transition of the rubber mount stiffness from static to dynamic values. Using the
experimentally estimated values of the rubber mount stiffness and damping, the dynamic response of the tested
spring-mass system using a metal-net rubber mount as the elastic element can be accurately reproduced.
