The aim of this study is to determine the effect of car speed on the stress on a coil spring. 60-s strain signals measured on the coil spring of a car that was driving at speeds of below 20 km/h, 40–50 km/h, and above 70 km/h were utilized as the input. From the dynamic analyses, it was found that the increase in speed was directly proportional to the increase in stress. Each increase of the speed of 10 km/h was followed by an increase of stress by almost 10 kPa. The highest stress was obtained when the car was driving at a speed above 70 km/h, which was 645 kPa. This value was 43.7% of the yield strength of the material. Although the stress that occurred was relatively small, it could cause damage to the coil spring because the component is subjected to loading continuously.
