毕业设计（论文） 题 目：基于UG的“凤舞”汽车轮毂 三维建模及有限元应力分析 院（系）别： 机电及自动化学院 专 业： 机械工程及自动化 级 别： 2008 学 号： 0811113026 姓 名： 林 飞 指导 老师： 黄致建 华侨大学教务处 2012年6月摘 要 现今的汽车车轮设计是汽车造型设计中一个不可遗漏的重点，车轮不仅要满足承重、通风（制动器散热）的需要，而且车轮造型直接关系着汽车车身设计的品位和档次。因此，如何进行车轮的造型设计，如何设计出有风格特色和审美情趣的车轮已成为车轮制造厂和设计者们最关心的问题，眼下越来越多的新技术正逐渐被应用到车轮的设计和开发上来。 本课题通过对中国传统文化的研究，归纳轮毂造型设计的要素，原则及其方法；并将其融合到汽车轮毂的造型设计中，从汽车造型的基本特征入手，结合视知觉心理学及工业设计美学，融入中国传统文化元素，进行具有中国特色的轮毂造型设计；运用UG三维建模及有限元分析技术,分析结构，进行模拟实验，以期设计出造型与结构一体化的具有中国特色的汽车轮毂。 本课题主要研究课题如下： 模拟车轮径向疲劳试验，确定合适的载荷及边界条件。 模拟车轮弯曲疲劳试验，确定合适的载荷及边界条件。 ：中国元素UG 有限元疲劳Abstract The modern automobile wheel design is a missing focus in automotive design , the wheel not only to meet the needs of load-bearing , ventilation (brake cooling), and the wheel shape is directly related to the quality and grade of the car body design . Therefore, how the design of the wheel , how to design a unique style and aesthetic appeal of the wheel has a wheel manufacturing plant, and the designers are most concerned about , and now more and more new technologies are gradually being applied to the design of the wheel up and development . Wheel vehicle department one of the main components of the force transfer between the components in the car with the ground, and plays a role in carrying, steering, drive, brake. In recent years, as the speed increases, the performance of the wheel has become the key factor of a direct impact on automotive braking safety, handling and stability, an important indicator of driving and ride comfort. The study reported that the U.S. with a truck accident: in the 1588 accident, 33.5% is caused by the failure of the wheels, bearings and tire components, wheel fasteners accounted for a large scale . The cause of the accident is attributed to the part of the wheel is so large, so it is necess
