【摘要】：目前,隨著經(jīng)濟(jì)社會(huì)的快速發(fā)展,面對(duì)建筑業(yè)需求的快速增長,混凝土的生產(chǎn)將由傳統(tǒng)、低效率制造向高效率、自動(dòng)化方向演進(jìn)。發(fā)達(dá)國家混凝土預(yù)制件的比例超過35%,甚至達(dá)到50%,由發(fā)達(dá)國家的建筑工業(yè)化進(jìn)程經(jīng)驗(yàn)可以看出,預(yù)制應(yīng)力混凝土結(jié)構(gòu)(PC構(gòu)件)將是未來建筑工業(yè)化方向之一。本文以建筑工業(yè)化中的PC構(gòu)件自動(dòng)化生產(chǎn)線為技術(shù)背景,對(duì)PC構(gòu)件堆垛機(jī)的技術(shù)特點(diǎn)和發(fā)展趨勢(shì)進(jìn)行了分析,調(diào)研了國內(nèi)部分PC構(gòu)件生產(chǎn)線的技術(shù)裝備,通過對(duì)PC構(gòu)件技術(shù)裝備的比較,并且結(jié)合項(xiàng)目實(shí)際應(yīng)用要求,對(duì)PC構(gòu)件自動(dòng)化生產(chǎn)線的重要裝備之一堆垛機(jī)的機(jī)械結(jié)構(gòu)和控制系統(tǒng)兩大部分進(jìn)行設(shè)計(jì)和研究。本文主要研究內(nèi)容如下:首先,結(jié)合堆垛機(jī)的實(shí)際使用要求和功能原理,同時(shí)借鑒起重運(yùn)輸設(shè)備的設(shè)計(jì)資料,對(duì)PC構(gòu)件堆垛機(jī)進(jìn)行總體方案設(shè)計(jì),隨后由堆垛機(jī)的總體方案結(jié)構(gòu),進(jìn)行部件結(jié)構(gòu)的詳細(xì)設(shè)計(jì)計(jì)算,同時(shí)借助三維建模設(shè)計(jì)軟件solidworks進(jìn)行模型建立。對(duì)于建立后的PC構(gòu)件堆垛機(jī)的模型需要檢驗(yàn)其主要受力部件的強(qiáng)度和剛度,運(yùn)用有限元分析軟件ANSYS WORKBENCH對(duì)其進(jìn)行強(qiáng)度、剛度分析,對(duì)于PC構(gòu)件堆垛機(jī)的設(shè)計(jì)結(jié)構(gòu)進(jìn)行靜力學(xué)分析后還需要研究PC構(gòu)件堆垛機(jī)的動(dòng)態(tài)特性,隨后對(duì)其進(jìn)行模態(tài)分析和頻率響應(yīng)分析,分析結(jié)構(gòu)在受到振動(dòng)時(shí)的響應(yīng)及各個(gè)部件的變形情況,進(jìn)而對(duì)PC構(gòu)件堆垛機(jī)的結(jié)構(gòu)進(jìn)行整體評(píng)估其優(yōu)劣。然后,基于PLC控制對(duì)PC構(gòu)件堆垛機(jī)的控制系統(tǒng)進(jìn)行設(shè)計(jì)和研究,通過對(duì)PC構(gòu)件堆垛機(jī)的工作原理及工作過程分析,設(shè)計(jì)堆垛機(jī)的控制作業(yè)流程圖;通過對(duì)速度控制、定位控制和認(rèn)址方式的分析,確定合適的控制方式,最后對(duì)主要控制系統(tǒng)硬件進(jìn)行合理選擇搭配。最后,運(yùn)用ADAMS對(duì)堆垛機(jī)的虛擬樣機(jī)進(jìn)行運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)進(jìn)行仿真分析研究,由堆垛機(jī)的動(dòng)力學(xué)和運(yùn)動(dòng)學(xué)的仿真研究分析,得到堆垛機(jī)在實(shí)際使用中的受力和運(yùn)動(dòng)變化特點(diǎn),為后續(xù)的相關(guān)設(shè)計(jì)研究提供可靠的依據(jù)。
[Abstract]:At present, with the rapid development of economy and society and the rapid growth of construction demand, the production of concrete will evolve from traditional, inefficient manufacturing to high efficiency and automation. The proportion of prefabricated concrete in developed countries is more than 35 or even 50. From the experience of industrialized construction in developed countries, it can be seen that precast stress concrete structure and PC members will be one of the directions of construction industrialization in the future. Based on the technology background of PC component automation production line in building industrialization, this paper analyzes the technical characteristics and development trend of PC component stacker, and investigates the technical equipment of some domestic PC component production lines. By comparing the technical equipment of PC components and combining with the practical application requirements of the project, the mechanical structure and control system of the stacker, one of the most important equipment in the PC component automation production line, are designed and studied. The main contents of this paper are as follows: first, combined with the actual use requirements and functional principles of the stacker crane, at the same time, using the design data of the crane transportation equipment for reference, the overall scheme design of the PC component stacker crane is carried out. Then the structure of the stacker is designed and calculated by the overall scheme structure of the stacker, and the model is built with the help of the 3D modeling and design software solidworks. The strength and stiffness of the main components of the PC stacker are tested by using the finite element analysis software ANSYS WORKBENCH, and the strength and stiffness of the PC stacker are analyzed by using the finite element analysis software ANSYS WORKBENCH. After the statics analysis of the design structure of the PC component stacker, it is necessary to study the dynamic characteristics of the PC component stacker, and then carry out modal analysis and frequency response analysis. The response of the structure to vibration and the deformation of each component are analyzed, and the structure of the PC component stacker is evaluated as a whole. Then, based on PLC control, the control system of PC component stacker is designed and studied. Through the analysis of the working principle and working process of PC component stacker, the control flow chart of the stacker is designed. The location control and address identification are analyzed, and the appropriate control mode is determined. Finally, the hardware of the main control system is reasonably selected and matched. Finally, the kinematics and dynamics of the virtual prototype of the stacker are analyzed by using ADAMS, and the dynamic and kinematic characteristics of the stacker are obtained by analyzing the dynamics and kinematics of the stacker. To provide a reliable basis for the subsequent related design research.
