1、上海工程技术大学毕业设计（论文）面包车车身造型的改进设计提供全套毕业论文，各专业都有摘要和汽车发展一样，汽车车身发展也历经了结构、性能、外形、安全节能与环保四个发展阶段。研究终极成果直指降低汽车燃油消耗量、提高汽车加速度和最大行驶速度三大经济性与操纵稳定性指标。具体包括气动力、气动力矩、汽车空气动力稳定性、汽车表面三维流场和表面压强以及汽车外形局部动力学特征等，并通过汽车的外形变化——车身造型予以体现。基于车身空气动力学改进的设计，空气动力学特性是影响汽车性能的最重要因素，它针对汽车给环境、能源带来的弊端，解决了
2、汽车动力性、安全性方面的诸多问题，而且与汽车造型技术相互依存。空气动力学性能越来越被重视，以低阻物体为出发点、减小正投影面积、追求楔型风格和表面平滑化等，而且计算流体动力学(CFD)必将给汽车空气动力学以新的面貌。FLUENT软件是目前对于汽车空气动力性计算较为先进的软件，对于车身造型改进来说有相当重要的作用，大大减少了设计造型时间，减少设计成本。关键词：车身设计，空气动力学，流体力学软件75上海工程技术大学毕业设计（论文）面包车车身造型的改进设计MicrobusbodydesignandimprovementA
