A similarity dynamic equation of an elastic rotation shaft with twin sides under the Gelileo coordinate conversion
在伽利略坐标变换下的二端面弹性转轴相似动力学方程

A novel similarity dynamic equation of an elastic rotation shaft with twin sides is built within the nonrelativistic theory, in this paper. We make a similarity between the dynamic equation of an elastic rotation shaft with twin sides and that under the ground coordinates. It can provide the theoretical background and method for the similarity engineering and the similarity calibration for quantification and measurement control.
