【摘要】：振动给料设备是近几十年来得到迅猛发展的一种新型机械,已经在各行各业得到广泛应用。随着采煤机械化程度的提高,对振动给料机的要求越来越高,因此,研究、设计、制造电磁振动给料机就成为一项十分重要的研究课题。目前电磁振动给料机的设计仍然存在很多技术上的问题,制定槽体的工艺过程仍旧依靠工艺人员使用一些简单的经验公式并结合个人多年的实践经验来确定,缺乏精确的理论分析手段。在电磁振动给料机设计领域,成形工艺研究由传统的“经验方式”到“定量分析方式”的过程,是现代科学发展的必然趋势。本文应用ANSYS有限元分析软件,以电磁振动给料机料槽为研究对象,主要做以下几个方面的工作。 (1)利用SolidWorks软件建立了电磁振动给料机料槽简化后的三维实体模型; (2)利用ANSYS软件与SolidWorks软件的接口功能,把其实体模型导入到ANSYS中,得到其几何模型; (3)在ANSYS中建立了电磁振动给料机料槽有限元模型; (4)进行静力分析,得到最大应力和最大位移,并校核是否满足强度要求,结果表明满足强度要求; (5)进行模态分析,得到固有频率和振型,判断是否满足亚共振的工作状态,若不满足,需要对结构进行改进。结果表明满足工作要求; (6)进行谐响应分析,得到幅频特性曲线,判断是否满足亚共振的工作状态,若不满足,需要对结构进行改进。结果表明满足工作要求。本文的研究过程和结果可以为我国振动机械的研制提供一条行之有效且可靠的途径,对其他类似的振动机械的研究也有参考价值。
[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.
