Backhoe design is very important in backhoe loader machines. While structurally examining the backhoe design, which is constantly in motion due to its design during operation, supporting static analysis studies with dynamic analysis will give better direction to the design studies. Since time-dependent sudden accelerations are the main cause of dynamic loads in backhoe components, in this study, the dynamic analysis of the backhoe design of a backhoe loader machine using the finite element method has been carried out.
For dynamic analysis, the backhoe loader design was analyzed in the Ansys Workbench program using 2 different models. The models to be used in dynamic analysis were determined from the motions of the backhoe loader machine in real life. The boundary conditions used in the models were the values determined as a result of the field testing of the backhoe design to be analyzed. In the results of the dynamic analysis, the time-dependent equivalent stresses, acceleration values and reaction forces in the cylinders were determined for both models (Model-1 and Model-2). The acceleration values were read as total acceleration by reference to the center of gravity of the boom and stick design. The determined values were examined through the graphics obtained from the motion analysis. These graphs allow to examine the relationship between the reaction forces occurring in the cylinders at equivalent stresses and the acceleration values that change over time.
With the conclusions made as a result of dynamic analysis, the positions where the maximum equivalent stress occurs, and the critical positions that will be referenced in the preparation of static analysis models in future studies have been determined. Thus, it is planned that this study will guide the studies to improve the backhoe design by comparing the results of static and dynamic analysis.
