汽车驾驶技巧与应用(下).doc

摘要
近几年,我国经济高速发展,随着国家大力进行基础设施建设,推动了运输业的发展,汽车运输一直以方便,安全,高效的特点位居运输业的主力地位。重卡行业可以说是突飞猛进,不断更新的技术让我们看得都有些目不暇接。
这次设计所作的是重型卡车的设计,具体的说是牵引车设计,根据卡车整体设计的多方面要求来塑造最理想的车身形状,运用艺术的手法、科学地表现卡车的功能、材料、工艺和结构特点。满足用户在实用性和情感方面的需求,根据用户的购买目的来做功能设计和造型设计,制造满足用户需求的车辆,这一点在轿车行业表现得已经很充分。同时,造型对车辆的操控性的影响也很重要,如可见度和车窗尺寸等。根据卡车整体设计的多方面要求来塑造最理想的车身形状。
卡车的设计最主要的造型设计趋势就是注重空气动力学原理,进而提高燃油经济性。卡车的造型采用流线型可以减小风阻,同时使造型更加富有动感。同时一个好的设计必须具有前瞻性,在外来科技的支持下能够做更好的造型设计,也就是适当做一些概念化设计。

Abstract
In recent years, China's rapid economic development, as China has strongly for infrastructure construction, promote the development of transport, motor transport has been a convenient, safe and efficient transportation among the main features of the status. Heavy truck industry can be said to be rapidly and continuously update the technology so that we see are some dizzying。
The design is heavy-duty trucks made in the design, specifically, tractor design, according to the overall design of the various trucks required to shape the ideal body shape, the way the art of applying science to the performance of the functions of trucks, materials, technology and structural features. Meet the practical and emotional aspects of user needs, according to the user's purpose for doing the design and function, design, manufacture vehicles to meet customer needs, it behaved in the car industry has been very good. Meanwhile, the shape of the vehicle's handling of the impact is also important, such as visibility and window size. According to the overall design of many truck requirements to shape the ideal body shape.
Truck design is the most important shape design trends focus on aerodynamics, thereby improving fuel economy. Trucks with streamlined modeling can reduce the wind resistance, while making styling more dynamic. A good design must also forward-looking, in support of foreign technology can do a better design, that is appropriate to do some conceptual designs.
Truck design is the most important shape desig
