The control system of the shaker (hydraulic and electrodynamic) provides the ability to test at random, for the case of multiple excitation when the impact of seismic effects.
Hydraulic shakers provide low-frequency region of large buoyant force and large displacement. Different shakers, vertical, horizontal design and multi-axis platform.
Multi-axis shaker - the movable platform, the hexapod type, with hydraulic actuators is kestikartano system micropositioning, working on the principle of parallel kinematics. The Stewart platform allows loading the object's acceleration as feedback, and move for a different kind of training and simulation motion.
Features of the hydraulic shaker:
