The rubber bellows, a key component of the air spring in automobiles, must be designed to guarantee a service life that exceeds a certain threshold under the fatigue load during operation. Fatigue tensile testing machines are employed to assess the durability of rubber. By inducing cyclic, tensile-compressive deformations at specific intervals, the fatigue characteristics of the rubber specimen can be measured, allowing for a rapid assessment of the relative durability of the rubber based on the collected data. Traditional crack measurement methods involved manual interruption of the testing apparatus, with individuals using a microscope camera to measure the length of cracks directly in each specimen. In this study, an automated measuring equipment was developed to halt the testing apparatus automatically, and capture and record crack measurements of the rubber specimens through a camera. This developed measuring equipment reduces unnecessary manual labor, and enhances productivity during the tensile testing process of the rubber. |
