本文分别从结构模态试验和理论计算两个方面分析了变截面转子轴系的动力特性,并以矿棉离心机转子为实例,用实模态图解识别法和用传递矩阵理论分析法进行定量计算,所得结果吻合良好,其表明所述方法的识别精度和可靠程度。在此基础上编制了能适用于多种边界条件的计算转子动力参数的计算机程序,便于应用推广。

Modal Test and Computer Analysis of Dynamic Parameters for A Rotor Zhu Kunquan Chen ShilinThis paper deals with the dynamic charactcristic analysis for a system with nonuniform rotating shafe by modal test and theoretical calculation.Take the centrifugal machine of mineral wool for example-the quantitative analysis has been made by means of the methods of identification parameters through graphical modal and theory of transfer matrices,respectively.Both results suit well,Therefore,these methods are shown to be precise and reliable,In order to apply and extend more conveniently the computer program which can be used to calculate dynamic parameters of rotor system with various boundary conditions has been worked out.
