This study analyzed the vibration of a transporter with rubber crawlers caused by road surfaces, and compared of the performance of rubber crawlers with and without iron cores to assess the human response to vibration (vibration perceptible to human body) and the reduction of vibration.
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.
