  SMALL & MEDIUM SCALE SHAKE TABLES

  2018915 · Abstract In this paper, based on fluid mechanical expressions and a new modified effective bulk modulus model of hydraulic oil built upon IFAS model (developed at the Institute für Fluidtechnische Antriebe und Steuerungen, RWTH Aachen university), an empirical nonlinear model for a servo-hydraulic uni-axial shaking table is developed.

  Implementation of real-time hybrid simulation using a large shake table ...

  2024415 · Abstract In recent decades, shake table real-time hybrid simulation (RTHS) has emerged as a promising seismic testing approach for complex engineering structures. However, the current shake table RTHS systems with actuators typically install the dynamic actuators on a reaction wall outside the table, which introduce interaction issues between …

  Model-based multi-metric control of uniaxial shake tables

  2013917 · A model-based multi-metric shake table control strategy is proposed to improve tracking of the desired acceleration of a uniaxial shake table, remaining robust to nonlinearities including changes in specimen condition. The proposed strategy is verified for the shake table testing of both linear and nonlinear structures.

  A mechanics-based virtual model of NEES-UCSD shake table …

  Large servo-hydraulic shaking table systems are essential tools in experimental earthquake engineering. They provide effective ways to subject structural components, substructures, or entire structural systems to dynamic excitations similar to those induced by real earthquakes. A typical shake table system includes mechanical, hydraulic, and electronic …

  Linear dynamic modeling of a uni‐axial servo‐hydraulic shaking table …

  This paper focuses on the development of a linear analytical model (even though servo-hydraulic actuation systems are inherently non-linear, especially for large amplitude simulations — near the performance capacity of the system — linearized models proved experimentally to be quite effective overall in capturing the salient features of shaking …
