Abstract

The purpose of this study is to predict the fatigue life of a lower arm as a vehicle is driven on a straight and turn roads. The measurement of strain signals was carried out by attaching a strain gauge to the left lower arm and driving it with an acceleration of 30 km/h. According to the results, the lowest fatigue life was obtained just as the vehicle turned clockwise, which was 2.6E+6 cycles to failure. This value was lower by 123% and 1,862% than it was driven straight and counter-clockwise. Similarity, when the vehicle turned to the right, the lower arm on the left side received a higher strain, contributing to a shorter fatigue life. © Published under licence by IOP Publishing Ltd.
