Design of a vibration-damping suspension or all-terrain vehicle cabs

Abstract

All-terrain vehicle operators may suffer a number of health effects, including back injuries, as a result of the vibration exposure they receive. A specially designed cab could reduce their exposure, especially to the particularly harmful low-frequency vibrations.

The low-frequency attenuation offered by several currently available cabs was evaluated. Cab suspensions incorporating either rubber supports, conventional or oil-based pneumatic supports, or springs and shock absorbers were produced and subjected to laboratory testing. The results of these tests were used in conjunction with computer modelling to develop a proposed cab suspension, and selection criteria. A suspension system capable of attenuating low-frequency vibration associated with vertical vibration, pitching, and rolling was recommended.
