Abstract

Bearings are among the most prevalent elements in civil-engineering buildings and mechanical machinery, and it have a wide range of uses. As a result, an improved bearing can significantly influence, potentially increasing reliability and efficiency. According to prior studies, rolling parts might minimise friction significantly compared to sliding action. Furthermore, contemporary manufacturing and material technologies enable the fabrication of an ideal structural bearing with a smoother and lower coefficient of friction surface. Different geometry models are designed using CatiaV5 software and manufactured utilising SLS 3D Printing in this study. Furthermore, all model designs are run through simulation using SIMSOLID software, and the prototypes is subjected to vibration analysis performance testing. The prototypes are put through surface validation, a scanning electron microscope (SEM), and a surface roughness tester are used to evaluate tribological behaviour. According to the overall findings, the majority of the optimized prototypes performed better. The force applied to the contact surface while a bearing is rotating is the main influencing factor. In contrast, when more force is applied, the SLS printed prototypes deform plastically and provide a smoother surface. Therefore, the smoother surface results in less machine vibration. The surface roughness results and SEM images provide a wealth of information to support the analysis. As a result, the optimized geomery bearing demonstrates the potential for use in upcoming applications.
