【摘要】:全自動(dòng)水泥裝車(chē)機(jī)是一種針對(duì)車(chē)廂碼垛形式的設(shè)備,能夠廣泛應(yīng)用于化工,糧食包裝,建材等多行業(yè)。能夠?qū)崿F(xiàn)袋裝水泥從生產(chǎn)線到卡車(chē)車(chē)廂的自動(dòng)化碼垛過(guò)程,可極大的提高生產(chǎn)效率。因此對(duì)全自動(dòng)水泥裝車(chē)機(jī)的研究有著重要意義。本文以全自動(dòng)水泥裝車(chē)機(jī)及其關(guān)鍵零部件為研究對(duì)象,采用ANSYS Workbench為工具建立有限元模型,對(duì)水泥裝車(chē)機(jī)的關(guān)鍵零部件進(jìn)行了靜力學(xué)分析,模態(tài)分析。分析計(jì)算了主機(jī)機(jī)架、碼垛裝置側(cè)翼板、閘門(mén)驅(qū)動(dòng)連桿等重要零件的強(qiáng)度、剛度性能以及主機(jī)機(jī)架和碼垛裝置的模態(tài)性能。通過(guò)對(duì)關(guān)鍵零部件的有限元分析結(jié)果相關(guān)參數(shù)的細(xì)致研究,發(fā)現(xiàn)其存在的薄弱點(diǎn)和可能在裝車(chē)機(jī)工作過(guò)程中導(dǎo)致的問(wèn)題,然后針對(duì)這些問(wèn)題對(duì)關(guān)鍵零部件進(jìn)行優(yōu)化設(shè)計(jì),得到一種新的優(yōu)化結(jié)構(gòu),并對(duì)新的優(yōu)化結(jié)構(gòu)進(jìn)行驗(yàn)證分析。以期望提升裝車(chē)機(jī)整機(jī)的工作性能。通過(guò)對(duì)主機(jī)關(guān)鍵零部件的各項(xiàng)性能參數(shù)進(jìn)行分析,發(fā)現(xiàn)了關(guān)鍵零部件:主機(jī)機(jī)架在普通工況和在極限工況下可能出現(xiàn)的剛度不足等問(wèn)題。同時(shí)結(jié)合主機(jī)機(jī)架質(zhì)量過(guò)重的問(wèn)題對(duì)機(jī)架作了拓?fù)鋬?yōu)化設(shè)計(jì),得到了新的優(yōu)化方案。并得到了優(yōu)化方案后的各項(xiàng)性能參數(shù),驗(yàn)證了其可行性。通過(guò)對(duì)側(cè)翼板靜力學(xué)分析結(jié)果的研究,得到了其在優(yōu)化空間內(nèi)的多組設(shè)計(jì)點(diǎn),并對(duì)其中一種最優(yōu)設(shè)計(jì)點(diǎn)進(jìn)行了驗(yàn)證。還通過(guò)對(duì)閘門(mén)驅(qū)動(dòng)連桿的靜力學(xué)分析得到了其不能滿足使用要求的結(jié)論并提出了驅(qū)動(dòng)連桿的優(yōu)化方案。本研究表明,第一代水泥裝車(chē)機(jī)主機(jī)的一些關(guān)鍵零部件不能完全滿足裝車(chē)機(jī)的多工況工作要求,基于有限元法針對(duì)這些關(guān)鍵零部件所提出的優(yōu)化方案對(duì)于提高裝車(chē)機(jī)關(guān)鍵零部件的工作性能有較高的可行性與實(shí)用意義?梢詾閷(shí)際生產(chǎn)提供理論指導(dǎo)和實(shí)踐支持。
[Abstract]:Automatic cement loading machine is a kind of equipment for the car stacking form, can be widely used in chemical, food packaging, building materials and other industries. Automatic palletizing process can realize the bagged cement from the production line to the truck, can greatly improve production efficiency. So the research of automatic cement loading machine has important significance. The automatic cement loading machine and its key parts as the research object, the finite element model is established by using ANSYS Workbench as a tool, the key parts of cement loading machine are analyzed by static analysis, modal analysis. The calculation of main frame, stacking device flank plate, gate drive rod and other important parts of the strength and stiffness properties as well as the host frame and stacking device modal properties. Detailed research based on the finite element analysis of the key parts of the relevant parameters, find the weak points of its existence And may result in the loader working process problems, aiming at the problems of the key parts of optimization design, a new optimization structure, and optimization of the new structure are presented. In order to enhance the performance of loading machine. Through the analysis of the parameters of the key parts of the host, found the key parts: the host frame in normal condition and may occur in extreme conditions of the stiffness problems. Combined with the host frame quality heavy topology optimization design of the frame, a new optimization scheme is obtained. The performance parameters are obtained after optimization scheme, through the research to verify its feasibility. On the right flank plate static analysis results, obtained in the optimization of multiple design point in space, and in which an optimal design scheme is verified. Through the gate The static analysis of connecting rod of gate drive obtained can meet the requirements of the conclusion and put forward the optimization scheme of driving link. This study shows that the first generation of cement loading machine for some key parts can not fully meet the requirements of multiple working loading machine, the feasibility and practical significance of optimization scheme of finite element method to solve these key parts the higher to improve the performance of the key parts of the loading machine based on can provide theoretical guidance and practical support for the actual production.
