OPTIMUM PARAMETER DECIDING METHOD FOR PSEUDODYNAMIC TEST, AND METHOD AND DEVICE FOR PSEUDODYNAMIC TEST

摘要

PROBLEM TO BE SOLVED: To perform a psedodynamic test with an optimum parameter always. ;SOLUTION: A test machine part for applying force to a test body is separated from a control system at points shown in C1-C3, for dummy operation with an input from a waveform generating means as zero. With various values set with damping constant C, a response waveform when a displacement data at a specified level is inputted is observed only for one sampling period, so that a value of C for optimum transient characteristics is obtained. An optimum C-value is similarly obtained for each value of spring constant K, and the spring constant K is measured in real time during test, and then an optimum C value corresponding to that value is used for pseudodynamic test.;COPYRIGHT: (C)2000,JPO
