An electro-hydraulic shaking table which is based on acceleration control is studied here. A three-variable control scheme is applied to achieve robustness, disturbance suppression and sufficient frequency bandwidth. Its acceleration response contains harmonics corresponding to sinusoidal input because of nonlinearities in the system.
The Model 7000 Vibration Test System might be the best choice for testing heavier test items or palletized loads. The complete system features a table sized to your application, a rugged hydraulic actuator, a reliable hydraulic power supply, and Lansmonts TouchTest Vibration Controller.
Shake table is used to provide earthquake simulation and to test the prototype and scaled model of the structure. Shake table generates harmonic motion in required direction to study the behaviour of an earthquake of similar pattern. In order to reproduce actual earthquake data, a six-degree of freedom electro-hydraulic shaking table is essential.

shake tables earthquake simulators HIGH-CAPACITY SHAKE TABLE, is designed to test high-scale models, close to real scale. It can simulate any recorded earthquake as well as apply user defined random profiles and common waveforms as sinusoidal triangle, etc.
2. The Hydraulic Servo Shaking Table. Figure 1 shows the experimental setup of the hydraulic servo shake table, which consists of a shaking table and real-time control system. The control system is controlled by a host-target type, where a commercial PC based on the Windows XP system is provided as the host computer, and the target computer is ...
Electro-hydraulic shaking table EHST is a useful experimental apparatus to real-time replicate the desired acceleration vibration signal for evaluating the performance of the tested specimen structural systems. A three axis six degree-of-freedom DOF EHST system with eight hydraulic actuators is presented in the paper.
In dynamic structure test, the specimen of hydraulic servo shaking table contains not only inertia load but also elastic load. The specimen herein is simplified as a spring-mass-damping system, and the mathematical model of the hydraulic servo shaking table is established by theoretical analysis. The coupling between specimens elastic load and shaking table itself produces resonance ...
