【摘要】:隨著我國經(jīng)濟(jì)建設(shè)的發(fā)展,小型工程機(jī)械的市場越見明朗,市場需求量逐漸增加。由于其體積小、機(jī)動靈活性好,性能也逐漸趕超大中型工程機(jī)械,小型工程機(jī)械開始發(fā)揮作用。作為小型工程機(jī)械的代表機(jī)型,滑移裝載機(jī)轉(zhuǎn)向半徑小、掛接不同的附件時(shí)可實(shí)現(xiàn)多種作業(yè)內(nèi)容,因此廣泛應(yīng)用于作業(yè)場地狹小、作業(yè)內(nèi)容復(fù)雜多變的工程項(xiàng)目中。 我國對滑移裝載機(jī)的研究剛剛起步,設(shè)計(jì)過程中可參考資料很少,用戶對滑移裝載機(jī)的認(rèn)識尚淺,該領(lǐng)域長期被國外工程機(jī)械商所壟斷。為普及廣大用戶對滑移裝載機(jī)的認(rèn)識,加快我國滑移裝載機(jī)的設(shè)計(jì)研究進(jìn)程,本文以GM750滑移裝載機(jī)為研究對象,從以下幾個(gè)方面進(jìn)行了探討。 首先從宏觀上介紹了滑移裝載機(jī)的主機(jī)結(jié)構(gòu)、傳動系統(tǒng)、轉(zhuǎn)向原理和工作裝置;在此基礎(chǔ)上進(jìn)行了整機(jī)的受力分析,包括橋荷分布情況的研究和轉(zhuǎn)向阻力的計(jì)算,提出了滑移轉(zhuǎn)向條件。 然后對工作裝置進(jìn)行了運(yùn)動學(xué)和動力學(xué)分析,得出了動臂舉升過程中鏟斗平移條件和系統(tǒng)動力學(xué)方程。應(yīng)用ADAMS軟件對GM750滑移裝載機(jī)進(jìn)行了實(shí)體建模和工作過程仿真。 最后采用ATmega16單片機(jī),進(jìn)行了鏟斗平移控制系統(tǒng)的硬件設(shè)計(jì),構(gòu)建了信號采集、傳輸以及信息處理的平臺;并選擇采用數(shù)字PID控制器實(shí)現(xiàn)鏟斗的平移控制;贛atlab/simulink平臺對平移控制系統(tǒng)進(jìn)行了數(shù)學(xué)建模和仿真,,從而得到了控制系統(tǒng)的性能參數(shù)。 本文所提出的滑移轉(zhuǎn)向條件和工作裝置仿真結(jié)果為滑移裝載機(jī)轉(zhuǎn)向系統(tǒng)和工作裝置的設(shè)計(jì)奠定了理論基礎(chǔ)。同時(shí)提供了一種鏟斗平移控制器硬件設(shè)計(jì)的基本方法,這些研究理論和方法可以應(yīng)用于滑移裝載機(jī)的設(shè)計(jì)開發(fā)。
[Abstract]:With the development of economic construction in our country, the market of small-scale construction machinery is more and more clear, and the market demand is increasing gradually. Because of its small size, good flexibility and performance, small-scale construction machinery began to play a role. As the representative model of small scale construction machinery, slip loader has small steering radius and can realize many kinds of operation contents when hanging different accessories, so it is widely used in engineering projects with narrow working space and complicated and changeable operation contents. In our country, the research on slip loader is just beginning, there are few reference materials in the design process, and the user's understanding of slip loader is still shallow, and this field has been monopolized by foreign construction machinery manufacturers for a long time. In order to popularize the understanding of slip loaders and speed up the design and research process of slip loaders in China, this paper takes GM750 sliding loaders as the research object and discusses them from the following aspects. First of all, the main structure, transmission system, steering principle and working device of slip loader are introduced, and the mechanical analysis of the whole machine is carried out, including the study of bridge load distribution and the calculation of steering resistance. The slip steering condition is proposed. Then the kinematics and dynamics analysis of the working device is carried out, and the conditions of bucket translation and the system dynamic equation during the lifting process of the moving arm are obtained. The solid modeling and working process simulation of GM750 slip loader are carried out by using ADAMS software. Finally, the hardware design of the bucket translation control system is carried out by using ATmega16 single chip microcomputer, and the platform of signal acquisition, transmission and information processing is constructed, and the digital PID controller is chosen to realize the displacement control of the bucket. Based on the Matlab/simulink platform, the mathematical modeling and simulation of the translation control system are carried out, and the performance parameters of the control system are obtained. The slip steering conditions proposed in this paper and the simulation results of the working device lay a theoretical foundation for the design of the steering system and the working device of the slip loader. At the same time, this paper provides a basic method of hardware design of bucket translation controller, which can be applied to the design and development of slip loader.
