Analysis of Deformation and Reliability of Rotors of High-Shear Homogenizer

目前高剪切均质机转子系统转速有不断提高的趋势,这对均质设备工作的可靠性提出了新的挑战。课题组以转子系统为研究对象,提出了高速转子齿径向位移的数学力学模型,在此基础上结合机械结构可靠性设计理论,以均质机转子的工作转速、齿全高、底厚和齿厚为变量,导出了转子最外层齿顶径向位移变形的可靠度计算函数。实例分析结合有限元计算结果表明该位移可靠度公式是正确的,实践也验证了该型号的高剪切均质机具有良好的工作可靠性。所得结论同时也为新型高剪切均质设备转子的设计与优化提供一定的参考依据。

In view of the trend of increasing rotational speed of rotor system in high-shear homogenizer,it poses a new challenge to the reliability of the equipment.The rotator system of the high-shear homogenizer based on its mechanical characters was studied.Taking the rotor system as the research object,a mathematical mechanical model of radial displacement of high-speed rotor tooth was proposed.Based on the reliability design theory of mechanical structure,the reliability calculation function of radial displacement and deformation of the outermost layer of the rotor was established by taking the rotational speed,tooth height,the thickness of plate and tooth thickness of the rotor of the homogenizeras variables.The example analysis and finite element calculation results show that the displacement reliability formula is correct.Practice also proved that this model of high-shear homogenizer has good reliability performance.The results also provide some reference for the design&optimization of the new high-shear homogenizers rotor.
