前装式垃圾车总布置设计(含CAD零件图装配图)(任务书,开题报告,文献摘要,外文翻译,论文说明书10000字,CAD图6张)
摘要
随着城市现代化建设进程加快、人口的增长、经济的发展以及现在人们生活水平的不断提高，垃圾的总产生量不断增加，垃圾的成分也发生了很大的变化。生活垃圾为固液混合态，成分十分复杂，伴随降解中产生的臭味气体及腐蚀性的液体，严重影响着城市环境。垃圾对都市生活人群的危害越来越大，十分严重地影响着人们的健康。环境保护意识增强使得环卫机械产业快速发展，压缩式垃圾转运车在垃圾处理和转运中占有重要地位。
目前我国在压缩式垃圾车尤其是前装式垃圾车领域为一片空白，压缩式垃圾车主要为后装式和侧装式，尚无国产厂商生产前装式垃圾车。本文主要根据国为以及国内垃圾车的发展历史进程和现状，参考国外目前前装式垃圾车的主流车型参数，进行底盘选型并对车身总布置进行设计，该车型以压缩率高、二次污染小、转运效率高、无需下车操作为主要特点，本次设计以满足我国目前日益增长的垃圾转运及需求为主要目的，旨在改善当前国内的形势。

Abstract
With the accelerated process of urban modernization, population growth, economic development and the continuous improvement of people's living standards, the output of domestic waste is increasing, and the composition of the garbage has also changed a lot. Garbage is more and more serious harm to human beings, and it is a serious threat to people's life and health. Garbage is mixed solid-liquid state, composition is complex and unstable, with explanation of odor and corrosion of leachate, a serious impact on the urban environment. Enhanced awareness of environmental protection makes the rapid development of environmental sanitation machinery industry, compression type garbage transfer vehicles in the garbage disposal and transportation occupies an important position.
At present, our country in the field of pre installed garbage trucks remaining vacancies, compression type garbage truck is mainly for the rear and side mounted, there is no domestic manufacturers to produce pre loaded garbage truck. In this paper, according to the garbage truck in foreign and domestic development history and present situation, refers to the domestic and foreign present mainstream before loading compression type garbage truck, selection of the chassis and the car body general arrangement design, the model to compress rate is high, little secondary pollution, high transfer efficiency, no need to get off operation as the main characteristics, the design to meet China's current growing refuse transfer and demand as the main purpose to improve the current situation of domestic.
Key Words：autoCAD、frontloadergarbagetruck、chassis arrangement design.
3.5整车质量参数估算
(1)垃圾车载质量mG
本车型垃圾车车厢容积为13m3，生活垃圾压缩后密度为0.4～0.6t/m3，本次设计取密度为0.5t/m3
所以mG=0.5*13=6.5t
(2)整备质量m0
整车整备质量是车上带上全部装备（包括工具、备胎等），加满燃料、水，但没有装货和载人时的整车质量。
整车整备质量在设计阶段需通过估算确定。通过收集和参照同类型垃圾车各部件和整车的相关质量数据，结合设计的结构特点、工艺水平等初步估算各总成、部件的质量，再累计构成整车整备质量。
参考国外同类型前装式垃圾车的装载量与整备质量之比，为本次设计选择适当的质量系数，然后按其装载量，计算整备质量。
