Design and Analysis of Mini Bajaj Gearbox.
Project Details
The intention of this project is to show how the gearbox housing from the Queen's Mini Baja vehicle's transmission was modeled and optimized using ANSYS to perform FEA. The typical bottom-up modeling approach was used to create the model of the gearbox housing. A simple analysis was first done by changing some of the design variables to see how they affected the integrity of the housing. We found that mesh refinement has a large effect on the accuracy of predicted deflections and stress. Therefore the mesh was refined mainly in specific locations within the housing structure. Optimization tools in ANSYS were used to calculate the optimum values for the design variables. The result of this optimization was a new design that had a maximum deflection of 0.0127 mm and a max stress of 126.7 MPa. The new design also show a 3% reduction in weight.
