Dynamic Performance for the Spindle System of the Composite Grinder Based on Transfer Matrix Method

摘要

Based on transfer matrix method, the dynamic model is established for the spindle system of a composite grinder, and the modal analysis is carried out. The lower-order modal shape and natural frequency in the determined condition is obtained, and the effects of the support span and the support stiffness on the dynamic characteristics of the spindle system are analyzed. The spindle system's structure is parameterized by the use of Matlab to improve the efficiency of the modeling and calculation.
