摘要
为确保大学生方程式汽车大赛(FSAE)赛车车架在实际应用中的稳定性与可靠性,同时实现轻量化并满足严格的安全标准,设计团队使用CATIA三维设计软件构建车架模型,并在ANSYS软件中进行有限元分析,以预测车架在不同工况下的动态响应。通过精确构建车架的三维模型并设定合适的材料属性和边界条件,以获取车架的固有频率和振动模态。为了验证仿真结果的准确性,通过模态试验测量了车架的振动响应,并将实验数据与仿真结果进行对比分析。试验结果证实了有限元分析在预测车架自由模态特性方面的精确性,验证了所采用分析方法的有效性,并为车架设计的进一步优化提供了坚实的理论基础。
To ensure the stability and reliability of the formula SAE(FSAE)frame in practical applications,while achieving lightweight design and meeting stringent safety standards,the design team utilizes three-dimensional design software CATIA to construct the frame model.Subsequently,finite element analysis is conducted in ANSYS software to predict the dynamic response of the frame under various conditions.By accurately constructing the three-dimensional model of the frame and setting appropriate material properties and boundary conditions,the natural frequency and vibration modes of the frame are obtained.To verify the accuracy of the simulation results,modal testing is also performed to measure the vibration response of the frame,and the experimental data are compared and analyzed with the simulation outcomes.The test results confirm the precision of finite element analysis in predicting the free modal characteristics of the frame,validate the effectiveness of the adopted analytical methods,and provide a solid theoretical foundation for further optimiza-tion of the frame design.
