【摘要】：目前,隨著經(jīng)濟社會的快速發(fā)展,面對建筑業(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、自動化方向演進。發(fā)達國家混凝土預(yù)制件的比例超過35%,甚至達到50%,由發(fā)達國家的建筑工業(yè)化進程經(jīng)驗可以看出,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)件自動化生產(chǎn)線為技術(shù)背景,對PC構(gòu)件堆垛機的技術(shù)特點和發(fā)展趨勢進行了分析,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PC構(gòu)件技術(shù)裝備的比較,并且結(jié)合項目實際應(yīng)用要求,對PC構(gòu)件自動化生產(chǎn)線的重要裝備之一堆垛機的機械結(jié)構(gòu)和控制系統(tǒng)兩大部分進行設(shè)計和研究。本文主要研究內(nèi)容如下:首先,結(jié)合堆垛機的實際使用要求和功能原理,同時借鑒起重運輸設(shè)備的設(shè)計資料,對PC構(gòu)件堆垛機進行總體方案設(shè)計,隨后由堆垛機的總體方案結(jié)構(gòu),進行部件結(jié)構(gòu)的詳細設(shè)計計算,同時借助三維建模設(shè)計軟件solidworks進行模型建立。對于建立后的PC構(gòu)件堆垛機的模型需要檢驗其主要受力部件的強度和剛度,運用有限元分析軟件ANSYS WORKBENCH對其進行強度、剛度分析,對于PC構(gòu)件堆垛機的設(shè)計結(jié)構(gòu)進行靜力學(xué)分析后還需要研究PC構(gòu)件堆垛機的動態(tài)特性,隨后對其進行模態(tài)分析和頻率響應(yīng)分析,分析結(jié)構(gòu)在受到振動時的響應(yīng)及各個部件的變形情況,進而對PC構(gòu)件堆垛機的結(jié)構(gòu)進行整體評估其優(yōu)劣。然后,基于PLC控制對PC構(gòu)件堆垛機的控制系統(tǒng)進行設(shè)計和研究,通過對PC構(gòu)件堆垛機的工作原理及工作過程分析,設(shè)計堆垛機的控制作業(yè)流程圖;通過對速度控制、定位控制和認(rèn)址方式的分析,確定合適的控制方式,最后對主要控制系統(tǒng)硬件進行合理選擇搭配。最后,運用ADAMS對堆垛機的虛擬樣機進行運動學(xué)和動力學(xué)進行仿真分析研究,由堆垛機的動力學(xué)和運動學(xué)的仿真研究分析,得到堆垛機在實際使用中的受力和運動變化特點,為后續(xù)的相關(guān)設(shè)計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.
