This study aims to analyze the stresses that occur in the lower arm and coil spring of an automotive subjected to dynamic loads. The strain signals produced from the lower arm and coil spring of a car were used as the loads in these dynamic analyses. Based on the simulation results, the stress that occurs in the lower arm was 244,612 kPa or only 54.35% of the yield strength of the SAE 1513 carbon steel. Meanwhile, the stress on the coil spring was 542,893 kPa or only 36.5% of the yield strength of the SAE 5160 carbon steel. In conclusion, the risk of failure of the lower arm is greater than the coil spring. Although the stresses that occurred were relatively small compared to the yield strength of the material, these stresses can still cause failure because the component receives loads continuously. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
