设计简介
摘 要
本次设计的题目是HGC3110自卸车设计。该自卸汽车是以CA1123P9K2L4E型货车底盘改装,自卸车近几十年来它在国内外获得迅速的发展与普及，它最大的优点是实现了卸货的机械化，从而提高卸货效率。不仅可以减轻工人劳动强度，还可以促进国家的经济建设速度，关系到国家重点建设项目的建设和发展。同时在自卸车研究和生产过程中，也带动了钢铁，化工等其它很多行业，又提供了大量的工作岗位，减轻就业压力，并日趋完善，成为系列化多品种的产品。因此，自卸车的发展是很有必要的。
所以本文以HGC3110型自卸车为设计题目，设计的主要内容有以下几个方面:确定HGC3110型自卸车的总体设计方案、对举升机构结构进行设计及其力学分析、对液压系统的设计、对车厢的结构及副车架的设计、对HGC3110型自卸车进行整车性能分析。最后所设计出来的自卸车能够承载5.5吨的货物，举升时间为15s的一款自卸车。

ABSTRACT
The design is the subject of the design modifications and HGC3110-type dump truck. CA1123P9K2L4E Dump Truck is the truck-based chassis modification, HGC3110-type dump truck at home and abroad in recent decades it was the rapid development and popularity of its greatest strengths is to achieve a discharge of mechanization, thereby enhancing the discharge efficiency. Not only can reduce the labor intensity of workers, but also to promote the country's economic construction speed, related to the key national construction projects, building and development. At the same time, research and production in the dump truck has also led the iron and steel, chemical, and other many industries, but also provide a large number of jobs and reduce the employment pressure, and gradually maturing as a series of product variety. Therefore, the development of dump truck is necessary.
Therefore, this paper HGC3110-Type dump truck for the design of the subject, the main elements of design are as follows: HGC3110-type dump truck to determine the overall design program. On the lifting body structure design and mechanical analysis. The design of the hydraulic system. The structure of the compartments and sub-frame design. HGC3110 type of dump truck for vehicle performance analysis. The last designed by the dump truck can carry5.5 tons of goods, lifting time of a dump truck for the 15s.
