摘要
为了保证赛车车架的强度及刚度符合大学生方程式赛车比赛的规则以及赛车的加速、操控及安全性能要求,在CATIA中建立车架三维模型,将几何模型导入ANSYS Workbench中建立车架的有限元模型并进行有限元分析,计算出赛车车架在静态、弯曲、制动及转弯工况下的强度以及车架的扭转和弯曲刚度。在理论上保证了赛车车架的安全性要求,实际做出的车架最终安全地完成了2013年的中国大学生方程式汽车大赛。
In order to guarantee strength and stiffness of the racing car frame to meet requirements of FSC, including the race rules, acceleration speed, riding and safety, 3D model of the frame was established in CATIA. The geometric model was put into ANSYS Workbench to build finite element model and carry out finite element analysis, calculating the strength of frame in static, bending, braking and turning working conditions, and stiffness of frame in torsion and bending. The safety of racing car frame was guaranteed from the view of theoretical principle, the actual racing car frame has completed its mission in 2013 FSC.
