摘　　要：利用三维建模软件UG对FSAE赛车车架建模。应用有限元软件ANSYS对FSAE车架动力学进行模态仿真,研究了FSAE车架的振动模态特性。通过仿真计算获得FSAE车架在自由状态下的固有频率和振动特性,同时结合模态试验分析,验证有限元分析的正确性。实验结果表明,实验误差在7%以内。Abstrac： The CAD model of FSAE racing car frame was set up by UG. The modal analysis was researched by ANSYS to study the modal characteristics of FSAE car frame. The natural frequencies and the dynamic characteristics of the FSAE car frame based on the condition of free state were calculated by finite element simulation. Combined with the modal test analysis, the correctness of finite element analysis was verified.Experimental results show that the experimental error within 7%.
