卧式振动离心机筛篮的设计与研究

Design and research of horizontal vibrating centrifuge screen basket

在对VM1400卧式振动离心机关键部件分析研究的基础上,设计了核心振动部件——筛篮。通过三维实体建模、有限元分析和实际工况采样试验等方法,得到了该筛篮在工作过程中的一系列动力学特性响应。综合有限元分析结果及对采样数据的计算,得出如下结论:在离心机稳态运行时,初级振动体受到较小激振力,由筛篮、主轴等组成的二级振动体可以获得较大的激振力,这是一个振动放大的过程,振动频率接近于工作频率,是非常理想的工作状态。

Based on the analysis and research of the key components of the VM1400 horizontal vibrating centrifuge, the core vibration component-screen basket is designed. A series of the dynamic characteristics response of the screen basket in the work process are obtained through the method of 3 D solid modeling,finite element analysis and sampling from actual conditions.Integrated the results of finite element analysis and calculation of sampling data, The following conclusions are drawn： When centrifuges work on the steady-state condition, the first vibration body case sustains less excited force, the second vibration body composed of screen basket, spindle and so on can obtain greater excited force. This is a process of vibration amplification,the vibration frequency is close to the operating frequency, and this is an ideal working state.
