| Abstract: | The paper discusses the computational methods of dynamic stiffness in multi-degree of freedom sup-port system and uses the results to evaluate the critical speeds of shaft system.Starting from two degrees of freedom support system,regularized filtering is derived to obtain the approximate optimal solution of dy-namic stiffness curve.This result is generalized to multi-degree freedom system and analytic functions of dynamic stiffness are given by cubic spline and experience fitting.An example proves that the proposed methods are efficient and exact enough. |
