Vibration Property of a Rubber Crawler System when Traveling Over Bumps

The human response to vibration was measured using an ISO standard device. Using a walking transporter traveling on an uneven road surface model, three different laden weights, four different road surface bumps dimensions, and four levels of vehicle speed were examined. The frequency-weighted r.m.s acceleration was measured at three locations - the center of gravity of the chassis, the handlebar and the carrying platform. The results revealed that the acceleration properties at each measurement point could be explained using a basic movement model.
