Analysis of whole body vibration of a two wheeler rider 2019-01-0406

Two-wheel motorcycles are preferred in many countries as it has some merits such as cheaper, easy to handle and gives higher fuel economy compared to three and four-wheel vehicles. Majority of the population in India falls under low and middle-income groups. Two-wheeler scatter to the needs of low and middle-income users and fill the gaps when public transport systems are inefficient or not available. Most of the people in India use a motorcycle for transportation. However, due to different road conditions, motorcycle rider experiences different health effects within a few years of their vehicle travel. This paper investigates the effect of vibration on a man commuter’s health. For this purpose, a mathematical model of a male rider’s body was considered, and a numerical analysis was carried out to assess the effect of vibration acting on the commuter during a two-wheeler ride under various road conditions for a chosen suspension system and presented. Road conditions were chosen based on different surface roughness values. The most affected rider’s body part due to the vibration of the two-wheeler was determined from the results. The results presented in this paper can be useful in understanding the vibrations induced in the human body while riding a two-wheeler at a particular velocity on a specific road surface.
