Abstract

A numerical method that permits the calculation of the time-dependent response of linear discrete systems is presented. The approach presented in this paper differs from direct integration methods, and is based on the concept of complex frequency response and fast Fourier transform which has been adapted for dynamic analysis. The method is unconditionally stable and very effective for the dynamic analysis of a system served by proportional and inertial feedback compared with direct integration methods. A Fortran coded program for dynamic analysis has been employed to calculate the transient-state response of the turning machine-tool structure.
