汽车座椅轻量化和舒适性的研究与有限元分析(含ProE三维图)(任务书,开题报告,外文翻译,论文说明书13800字,ProE图)
摘 要
随着全球汽车的与日俱增，环境污染和世界能源短缺问题日益严峻，汽车的舒适性和轻量化越来越受到人们的重视。汽车座椅是与人体直接接触的部件，所以对它的研究和改良肯定很重要。座椅的轻量化和舒适性的理论和方法被广泛的肯定。在此同时，业界也越来越关注如何提高汽车座椅的舒适性并尽可能的轻量化，以提高乘客的舒适度以及降低燃油油耗和减少排放。
本论文主要介绍汽车座椅的发展历史和现状,介绍汽车座椅的结构和材料应用；对座椅轻量化和舒适性的设计和研究方法进行分析与研究，以传统的座椅为基础，利用proe软件设计新型铝合金汽车座椅，对座椅材料应用和结构上进行轻量化和舒适性设计，使座椅材料应用和结构上的轻量化和舒适性得以改善。
运用Ansys有限元软件分析座椅骨架的静态特性和模态特性，证实了设计的新型铝合金座椅骨架在静强度和模态方面都达到了国家标准的要求，说明了轻量化设计的成功。

Vehicle seat lightweighting and comfort in the research and analysis
Abstract
With the increasing of the global car, the problem of the pollution of the environment and the world's energy shortage is more and more serious, the vehicle's comfort and lightweight more and more get people's attention. Vehicle seat is direct contact with human body parts, so the research and improvement of it would be very important. The lightweight and comfort of the seat of the theory and methods are widely. At the same time, the industry is becoming more and more focus on how to improve the comfort of car seat and lightweight as possible, in order to improve the passenger comfort and reduce fuel consumption and emissions.
This paper mainly introduces the development history and current situation of vehicle seat and introduces the structure of the vehicle seat and materials; On the basis of the traditional seat, we use proe software to design new aluminum vehicle seat and design the seat material and structure about lightweighting and comfort ,this makes the seat materials and structure of lightweight and comfort can be improved.
We use Ansys software to analysis frame of the static and modal characteristics, this confirmed the design of new aluminum seat of car in static strength and modal has reached the requirement of national standard, shows the success of the lightweight design.
  Key words: Car; The seat; Static characteristic; Comfort; Lightweight
