| Summary: | Spring suspension is one of the important parts of automobile components that supports and holds the body of an automobile from shaking and vibration. Driving becomes uncomfortable when an automobile traverses high-and low-magnitude roads, such as hills and road roughness, respectively. Therefore, this study aims to investigate the fatigue strain signal characteristic of an automobile spring suspension when driving on different road surfaces and its effect on fatigue damage. In this study, a strain gauge was mounted on the automobile spring suspension system and connected to the data acquisition set to capture the actual fatigue strain signal during normal driving condition. The fatigue strain signal characteristic was analyzed through a statistical method. Then, the fatigue damage of the automobile spring suspension system was determined using commercial finite element software. Results indicate that the characteristic of the automobile spring suspension system is influenced significantly by the type of road surfaces. Thus, this condition contributes to different damages to the automobile spring suspension system. |
