    an overview of control schemes for hydraulic shaking tables

    Shaking table testing is a common experimental method in earthquake engineering for performance assessment of structures subjected to dynamic excitations. As most shaking tables are driven by servo hydraulic actuators to meet the potentially significant force stroke demand, the review is restricted to hydraulic shaking tables

    random vibration control of a hydraulic shaking table

    Abstract A multi-input multi-output (MIMO) random vibration control method is proposed for a multi-axis hydraulic shaking table system to replicate the reference power spectral density (PSD). Kinematics analysis is presented to reduce cross-coupling between the axes of the hydraulic shaking table

    linear dynamic modeling of a uni‐axial servo‐hydraulic

    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 table dynamics) of a uni‐axial, servo‐hydraulic, …

    design scheme of hydraulic control system for shake table

    The shaking table is driven horizontally by eight (75,000 lbs) hydraulic actuators, and vertically by four (75,000 lbs) actuators located in the pit below. The actuators have swivel joints at each end so they can rotate to accommodate components of motion perpendicular to their direction of extension
