| Title | Design of Roll Cages for Reducing Car-Body Deformation | ||
| Keyword | |||
| Abstract | This thesis investigates the effects of roll cages and stiffening rods on car-body deformation by using the software package Ansys, together with the CAD software ProE, to perform finite element analysis. Based on the measurement of a real car body, a CAD model was first created using ProE, and imported to Ansys to perform static analysis with loadings applied on various parts of the model. The analysis results were set as the baseline for later use. Then, several types of commercially-available roll cages and stiffening rods were modeled and added to the baseline model to create another 9 sets of modified models, which consequently were analyzed and the results compared with the baseline. In this research, finite element static analyses were executed on 10 models with various types of roll cages and stiffening rods and with the same loading and boundary conditions. The goal was to find the best model with the minimum deformation and maximum stiffness. The model coded TC3-XU, although the heaviest, was superior to all others in bending stiffness. The model coded TC2000-V performed better than TC3-XU in torsion stiffness, but the latter could replace the U-shaped rod by a lighter and stronger material. Therefore, according to 8 discussion remarks, TC3-XU was concluded as the best model for this research. |
