NUT车队赛车车架改进设计研究ANSYS仿真

摘要大学生方程式赛车的车架是整车零部件的装配基础以及赛车所受载荷的承载基体。以大学生方程式汽车大赛为课题研究背景，基于我校 NUT 车队连续 5 年的参赛经验，应用汽车设计、汽车理论、大赛规则及该领域相关文献对车队 2015 赛季赛车车架进行了改进设计研究，选择了合适的车架材料，确定了车架加工工艺，并使用 CATIA 软件对车架改进方案进行改进设计建模，使用 ANSYS Workbench 分析平台对改进后车架方案进行四种行驶工况的受力分析、六阶模态分析以及车架的刚度强度分析，结果显示改进车架基本实现了预期目标，对 2016 赛季 NUT 车队赛车车架设计制造有一定指导意义。69526

Title The Improved Design Study Of Racing Frame Based On The Frame Of NUT2015

Abstract

Racing frame of FSAE is the base of car parts Assembly and car load bearing substrate. FSAE for the research background and based on the five years of competition experience of NUT team of Nanjing University of Science and Technology. Using the theory of automotive design, the principle, rules of the race at home and abroad and the research of this field to carry out our study, determine the selection of material and processing technology and modeling the improved racing frame design with CATIA，then using the software of finite element ANSYS Workbench to carry out the analysts of six modal and bending and torsional stiffness. The results achieved the expected goals of improved frame and indicated that the research is instructive for the racing frame design and manufacture of NUT2016.

Keywords FSAE Racing frame Finite element method Modal analysis Bending and torsional stiffness
