| Title | Research of Reinforcement Structure Design on Rear Deformation of High Rigidity Car Body | ||
| Keyword | |||
| Abstract | Abstract The thesis discusses the influence of the corner reinforcement structure and structural tie rods on the deformation of the rear of the high-rigidity car body. Through ProE (Pro/ENGINEER) and Ansys, the reinforcement structure, tie rods and anti-roll cage are analyzed and compared on the deformation of the rear of the car. Based on the actual car body data, use ProE software to draw the benchmark model of the model, and import it into Ansys for static analysis, apply loads to the left and right shock towers at the rear of the car and fix the front shock towers, analyze and record the displacement of the observation point as a follow-up Benchmark for analysis and comparison. Then refer to the existing commercially available anti-roll cage and structural tie rods, draw the reinforcement structure with its reinforcement mechanism, draw the reinforcement structure through ProE and add it to the benchmark model, and then import it into Ansys to repeat the static analysis and record the data for subsequent comparisons. In this research, 24 groups of models with different reinforcement structures, and performs static analysis under the same constraints, and compares their deformation and rigidity, and finds out that the model with the smallest deformation and the highest rigidity is the most ideal model. In the final 2L model, in the torsional rigidity experiment, both the maximum deformation and the deformation of the detection point are smaller than other single pieces, and are also lower than the K model of the control group. Therefore, the one with the best single-piece benefit is 2L , the multi-piece reinforcement part is the best result of CD_UP+2L, which also proves that the simultaneous reinforcement of multiple parts can indeed improve the rigidity. |
