| 摘 要： | 车架作为FSAE赛车的主要承载体,直接影响着赛车的加速、操控和安全性能,车架的强度与刚度在赛车的设计和制造中显得尤为重要。根据大学生方程式汽车大赛规则要求,在CATIA中建立车架的三维几何模型,然后将几何模型导入到Hypermesh中,建立车架的有限元模型。再利用Radioss进行弯曲、满载加速、满载转弯和扭转工况下的车架强度和刚度的分析。最后通过钢管尺寸优化等措施进行优化设计与分析,实现了车架减轻质量6 kg;通过结构优化,赛车的整体性能也得以提高。

| Abstract: | Frame as the main carrier of FSAE car, directly affects the cares acceleration, handling and safety. Strength and stiffness of the frame is especially important in the car＇s design and manufacturing. Firstly, 3D model of the frame was established in CATIA according to the rules requirements of Formula SAE. Secondly,the geometry model was imported into Hypermesh to set up the finite element model of the frame. Then strength analysis and stiffness analysis of bent, full accelerated, full turning and reverse working condition were done in Radioss. Finally, the mass of the frame was reduced by 6 kg as the optimization design and analysis measures of steel tube size optimization and so on, also the whole performance of the racing car was improved through the optimization of structure. |
