三维建模及有限元应力分析
论文摘要:
车轮是左右整车性能最重要的安全部件,不仅要承受静态时车辆本身垂直方向的自重载荷,更需要承受车辆行驶中来自各个方向因起动、制动、转弯、路面凹凸不平等各种动态载荷所产生的不规则应力之考验。它的轴向跳动和径向跳动精度,又直接影响到整车行驶中的平稳性、抓地性、偏摆性、制动性等行驶性能。随着汽车工业的迅猛的发展,铝合金轮毂的应用越来越普遍。铝合金轮毂具有重量轻,降低油耗;散热性好,提高轮胎寿命;缓冲和吸震性好;造型美观,易加工,耐腐蚀等优点。但中国铝合金车轮行业普遍存在设计周期长,制造成本高等问题。在汽车设计制造中计算机辅助设计是必然趋势,因此采用先进的三维CAD软件和大型CAE软件对汽车铝合金轮毂进行结构设计,有利于缩短设计周期,提高产品质量。目前,在中国用有限单元法对铝合金车轮进行研究还处在起步阶段。只有少数的科研院所和高校对钢制车轮进行有限元分析研究。因此,有必要把有限元技术应用到铝合金车轮上,以解决生产实际问题。
本课题:基于UG的“火轮”汽车轮毂三维建模及有限元应力分析,是从汽车轮毂基本特征入手并结合工业设计美学,打造出具有中国元素的车轮,应用UG软件三维建模并完成网格划分,用有限元分析模块做出强度分析。
通过此次设计学****并熟练掌握UG软件的建模与有限元分析功能,对车轮做强度分析,为车轮结构优化设计提供依据。

Abstract
Wheel is the most important ponent of the vehicle performance, Not only to bear the load of the vehicle itself static weight on vertically. And withstand the test of vehicles from all directions, starting、braking、cornering、uneven surface and other dynamic loads generated by the irregular stress. Its axial and radial runout accuracy the smooth, grip, swing, braking and driving performance. By the rapid development of automobile industry, the increasing application of aluminum alloy wheels. Aluminum alloy wheels with light weight, lower fuel consumption; good , improve tire life; buffering and shock absorption; attractive appearance, ease of processing, corrosion resistance, in China aluminum alloy wheel industry cycles, is an inevitable trend in automotive design and the use of 3D CAD software and large CAE software for car aluminum wheel structure design, is benefit to shorten the design cycle and improve the quality of present, in China adopt the finite element method on the aluminum alloy wheels research is still in its initial , it is necessary to adopt the finite element technique on aluminum alloy wheel, to solve the practical problems of production.
This project:Based on UG establish "steamer" alloy wheel 3D modeling and finite element stress analysis, Start
