【摘要】：振動(dòng)給料設(shè)備是近幾十年來(lái)得到迅猛發(fā)展的一種新型機(jī)械,已經(jīng)在各行各業(yè)得到廣泛應(yīng)用。隨著采煤機(jī)械化程度的提高,對(duì)振動(dòng)給料機(jī)的要求越來(lái)越高,因此,研究、設(shè)計(jì)、制造電磁振動(dòng)給料機(jī)就成為一項(xiàng)十分重要的研究課題。目前電磁振動(dòng)給料機(jī)的設(shè)計(jì)仍然存在很多技術(shù)上的問(wèn)題,制定槽體的工藝過(guò)程仍舊依靠工藝人員使用一些簡(jiǎn)單的經(jīng)驗(yàn)公式并結(jié)合個(gè)人多年的實(shí)踐經(jīng)驗(yàn)來(lái)確定,缺乏精確的理論分析手段。在電磁振動(dòng)給料機(jī)設(shè)計(jì)領(lǐng)域,成形工藝研究由傳統(tǒng)的“經(jīng)驗(yàn)方式”到“定量分析方式”的過(guò)程,是現(xiàn)代科學(xué)發(fā)展的必然趨勢(shì)。 本文應(yīng)用ANSYS有限元分析軟件,以電磁振動(dòng)給料機(jī)料槽為研究對(duì)象,主要做以下幾個(gè)方面的工作。 (1)利用SolidWorks軟件建立了電磁振動(dòng)給料機(jī)料槽簡(jiǎn)化后的三維實(shí)體模型; (2)利用ANSYS軟件與SolidWorks軟件的接口功能,把其實(shí)體模型導(dǎo)入到ANSYS中,得到其幾何模型; (3)在ANSYS中建立了電磁振動(dòng)給料機(jī)料槽有限元模型; (4)進(jìn)行靜力分析,得到最大應(yīng)力和最大位移,并校核是否滿足強(qiáng)度要求,結(jié)果表明滿足強(qiáng)度要求; (5)進(jìn)行模態(tài)分析,得到固有頻率和振型,判斷是否滿足亞共振的工作狀態(tài),若不滿足,需要對(duì)結(jié)構(gòu)進(jìn)行改進(jìn)。結(jié)果表明滿足工作要求; (6)進(jìn)行諧響應(yīng)分析,得到幅頻特性曲線,判斷是否滿足亞共振的工作狀態(tài),若不滿足,需要對(duì)結(jié)構(gòu)進(jìn)行改進(jìn)。結(jié)果表明滿足工作要求。 本文的研究過(guò)程和結(jié)果可以為我國(guó)振動(dòng)機(jī)械的研制提供一條行之有效且可靠的途徑,對(duì)其他類似的振動(dòng)機(jī)械的研究也有參考價(jià)值。
[Abstract]:Vibrating feeding equipment is a new type of machinery which has been developed rapidly in recent decades and has been widely used in various industries. With the improvement of mechanization of coal mining, the requirement of vibrating feeder is becoming higher and higher. Therefore, the research, design and manufacture of electromagnetic vibrating feeder has become a very important research topic. At present, there are still many technical problems in the design of the electromagnetic vibration feeder. The process of making the tank body still depends on some simple empirical formulas used by the technologists and personal practical experience for many years to determine the process. Lack of accurate theoretical analysis means. In the field of electromagnetic vibration feeder design, the research of forming process from the traditional "experience mode" to "quantitative analysis mode" is the inevitable trend of the development of modern science. In this paper, ANSYS finite element analysis software is used to study the feeding tank of electromagnetic vibration feeder. The main work is as follows: (1) the simplified three-dimensional solid model of electromagnetic vibration feeder tank is established by using SolidWorks software; (2) the interface function between ANSYS software and SolidWorks software is used. The geometric model is obtained by introducing its solid model into ANSYS; (3) the finite element model of electromagnetic vibration feeder tank is established in ANSYS; (4) the maximum stress and displacement are obtained by static analysis. The results show that the strength requirement is satisfied. (5) the modal analysis is carried out to obtain the natural frequency and mode shape to determine whether the working state of sub-resonance is satisfied or not. If not, the structure needs to be improved. The results show that the working requirements are satisfied; (6) the amplitude-frequency characteristic curve is obtained by harmonic response analysis, and the working state of sub-resonance is judged. If not, the structure should be improved. The results show that the working requirements are satisfied. The research process and results of this paper can provide an effective and reliable way for the development of vibration machinery in China, and also have reference value for other similar vibration machinery research.
