the servo valveactuated test assembly further comprising a vibration test fixture having a slip table and a piston actuator affixed to the slip table, the output flow of hydraulic fluid from the control output ports of the servo valve directed to the piston for applying a reciproing linear motion to the piston; and in which the output flow ...

This paper proposed two degree of freedom(DOF) control strategies for the shaking tables system composed of two identical redundantdrive electrohydraulic servo shaking table: six DOFs control strategy and twelve DOFs control strategy.

Apr 05, 2020 · Synchronous control of the two electrohydraulic shaking tables is transformed into the motion control of a twodegreeoffreedom overconstrained shaking table driven by 10 actuators. The force control loop based on the null space of the Jacobian matrix is developed to reduce the crosscoupling among the actuators.

A hydraulic shaking table has obvious frictional characteristics that will result in the deterioration of test waveforms and affect test accuracy. In this study, the influence of nonlinear friction for a hydraulic shaking table test system is analyzed briefly. For dynamic friction parameters and unknown system load characteristics, a mathematical model is developed based on the LuGre friction ...

Servohydraulic shaker table techniques are described which simplify inertial loading simulation tests with lower fixturing costs. The system is based on the reprocessing of multichannel acceleration service data by offline computer, digital filtering methods into a .

A complete turnkey system includes the shaker platform, a hydraulic power supply with a sequential pump controller (typically loed in a utility room adjacent to the centrifuge enclosure), a hydraulic distribution and control system (mounted on the centrifuge arm), two PVL SC2000 servocontrollers, two PVL PA2000 power amplifiers, one PVL ...

The servohydraulic shaker uses a very fast acting servo valve to control the release of oil, stored at high pressure (280 bar) in accumulators, to drive the actuators connected to a shaking table. A hydraulic power pack and high pressure slip rings allow the accumulators to be recharged after each earthquake so that multiple earthquakes can be ...
