THE FEEDBACK AUTOMATION IDENTIFICATION OF THE BASE IMPORTING SPECTRUM IN ANSYS'S PSD ANALYSIS

In this paper, a program for feedback automation controlin the ANSYS's PSD(powerspectrum density) analysis is developed in the powerful APDL(ANSYS ParametricDesign Language) language. Multi-table is used to store the base importingspectrum, which has lifted the limit that the base importing spectrum canonly be described by less than 50 data points. So the base importingspectrum can be identified via a feedback. The computing efficiency andprecision are improved greatly.
