NUMERICAL MODELING AND EXPERIMENTAL IDENTIFICATION OF THE EUCENTRE TREES LAB SHAKE TABLE
This paper present two models of the EUCENTRE TREESLab high performance uni-axial shake table based on their numerical implementation using the Matlab system-modeling package Simulink. The first model uses a simplified linearized servovalve actuator system while the second uses a realistic detailed nonlinear system. These numerical models incorporate the inherent dynamic characteristics of the various components of the shake table system and their interaction. A comprehensive set of random and periodic tests were conducted on the shake table in order to determine all of the parameters involved in the numerical models. Finally, both models were validated with the real shake table by comparing their transfer functions with the experimentally calculated transfer function.
