Dynamic Stress/Strain Measurement and Analysis of the Aluminum Alloy Road Wheel through F1 Circuit Ultimate Driving Test

F1 서킷 극한주행시험을 통한 알루미늄 알로이 휠의 동응력/변형률 계측 및 분석

It is generally known that the automotive road wheel involves the non-proportional multiaxial loading condition, therefore the measuring dynamic stress and strain in driving state is very important to predict an endurance characteristic of the automotive road wheel. In this study, the ultimate driving test using F1 circuit with respect to 2 kinds of velocity conditions have been carried out in order to measure dynamic stress, strain of the wheel and acceleration of a vehicle. Based on the measured results, the characteristics of dynamic stress generation have been analyzed, and factors which have effect on the dynamic stress generation have been studied.
