摘要：

In this research, a linear-elastic FEM (finite element method) model of tooling system under the unconstrained condition was established for a BT40 tooling system. The natural frequency and the modal shape of the tooling system computed from the FEM analysis were verified against the structural modal parameters obtained from experimental modal analysis. In the basis of rational FEM model of tooling system, the changing law its length and diameter influence to structural modal parameters was investigated. After that, with the machine vibration testing of spindle raising speed idle running, further study on the law about the changing length and diameter of tooling system influence to vibration characteristic of spindle-tool system, the researched results will be a theoretical basis to evaluate the dynamic performance of other type's tooling system.
