Researchers compared the structural integrity of backhoe loader bucket teeth made by welding and casting methods.
The study used finite element analysis to examine the stress and strain on bucket teeth made by different manufacturing methods. The researchers found that bucket teeth made by casting are more robust than those made by welding. This suggests that casting may be a better method for producing bucket teeth, but the study did not provide a direct comparison of the two methods.
Abstract
The teeth in the Backhoe-Loader bucket are exposed to different dynamic loading conditions throughout the machine's usage. According to the manufacturer, the bucket teeth can be produced as dual piece, welded together, or directly cast. Due to the distinctive design of the bucket tooth, reading stress and strain values on the tooth is challenging. Therefore, it is essential to conduct a structural analysis of the design using the finite element method in a computer environment. In this study, the change in stress-strain on the bucket tooth resulting from transitioning from the currently produced dual-piece design to a cast design has been examined. As a result of this change, it is anticipated that the cast tooth will be more robust compared to the welded manufacturing, and the results have been compared accordingly.
