基于catia的大型客车车身设计说明书（论文）+CAD图纸+catia三维模型+外文翻译及原文-毕业作品网站

摘要

大型客车由发动机、底盘、车身和电器设备等几大部分构成。研究表明，大型客车车身约占整车质量的30%～40%，在空载情况下，有70%的燃油消耗在车身质量上，同时，车身是汽车各组成部分中唯一具有吸收碰撞能量能力的，在碰撞发生时通过合理变形对车内乘员进行防护。因此对于大型客车车身的设计，能够有效的提高车辆的动力性、燃油经济性和行驶稳定性。

本文以KLQ6100G城市公交车为例，参照KLQ6100G城市公交车已有汽车底盘，用三维设计软件（CATIA）对该公共汽车的车身造型、内饰布置、乘客区布置等各种汽车布置进行设计与研究。在设计该车布置时，参考以往同类型设计研究方法，对该车的各部件装饰形式进行了认真分析，并严格按照公共汽车制造标准进行设计。在能够提高载客量的基础上优化外形设计，使其美观大方，并且依靠内部结构设计，提高乘客乘坐时的舒适性，增强乘客的乘坐体验。

由于我国城市化进程的加速以及居住郊区化带来的交通需求，大型客车在解决城市交通需求和市场需求的角度上变得越来越重要。对大型客车车身造型及总布置的研究，有利于我国城市公交的发展。在贯彻公共交通“安全、舒适、快捷、经济、方便”的基本原则下，本论文有一定的应用和参考价值。

Content: Large passenger cars from the engine, chassis, body and electrical equipment, and other major components. The study shows that the large passenger car body occupies about 30% to 40% of the vehicle quality, in the case of no load, 70% of the fuel consumption in the body quality, while the body is the only part of the car with the ability to absorb collision energy Of the collision occurred in the car through a reasonable deformation of the occupant protection. Therefore, the design of large passenger car body, can effectively improve the vehicle's power, fuel economy and driving stability.

This paper to KLQ 6 1 00G city bus, for example, with reference to KLQ 6 1 00G city bus has a car chassis, with three-dimensional design software (CATIA) on the bus body shape, interior layout, passenger area layout and other automotive layout design and research. In the design of the car layout, with reference to the same type of design and research methods, the car parts of the decorative form awakened a careful analysis, and in strict accordance with the bus manufacturing standards for design. In the process of theoretical analysis and modeling, learn the latest body design information, the design of repeated changes in the capacity to improve the basis of the volume to optimize the shape design, so beautiful and generous, and rely on the internal structure of the design to improve passenger comfort , To enhance the passenger's ride experience.

Due to the acceleration of the urbanization process and the traffic demand caused by the suburbanization, the large passenger car is becoming more and more important in solving the urban traffic demand and market demand. The study on the shape and layout of large passenger cars is conducive to the development of urban public transport in China. Under the basic principle of "safe, comfortable, fast, economical and convenient" for public transportation, this paper has certain application and reference value.
