摘 要
本次設(shè)計(jì)的題目是HGC3110自卸車設(shè)計(jì)。該自卸汽車是以CA1123P9K2L4E型貨車底盤改裝,自卸車近幾十年來它在國內(nèi)外獲得迅速的發(fā)展與普及，它最大的優(yōu)點(diǎn)是實(shí)現(xiàn)了卸貨的機(jī)械化，從而提高卸貨效率。不僅可以減輕工人勞動(dòng)強(qiáng)度，還可以促進(jìn)國家的經(jīng)濟(jì)建設(shè)速度，關(guān)系到國家重點(diǎn)建設(shè)項(xiàng)目的建設(shè)和發(fā)展。同時(shí)在自卸車研究和生產(chǎn)過程中，也帶動(dòng)了鋼鐵，化工等其它很多行業(yè)，又提供了大量的工作崗位，減輕就業(yè)壓力，并日趨完善，成為系列化多品種的產(chǎn)品。因此，自卸車的發(fā)展是很有必要的。
所以本文以HGC3110型自卸車為設(shè)計(jì)題目，設(shè)計(jì)的主要內(nèi)容有以下幾個(gè)方面:確定HGC3110型自卸車的總體設(shè)計(jì)方案、對(duì)舉升機(jī)構(gòu)結(jié)構(gòu)進(jìn)行設(shè)計(jì)及其力學(xué)分析、對(duì)液壓系統(tǒng)的設(shè)計(jì)、對(duì)車廂的結(jié)構(gòu)及副車架的設(shè)計(jì)、對(duì)HGC3110型自卸車進(jìn)行整車性能分析。最后所設(shè)計(jì)出來的自卸車能夠承載5.5噸的貨物，舉升時(shí)間為15s的一款自卸車。

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.
