Multi Axes Shake Tables

BISS 3-Axes, 6 DOF Shake tables are designed to perform seismic qualification, solid liquefaction and vibration tests on building models as well as for engineering qualification of components and assemblies for earth quake and vibration resistance.

The tables are designed for rigid mounting of specimens for transfer of required acceleration history. It also ensures the c.g of the test object can be anywhere within the table work space. Table motion is generated through precision and synchronous control of 8 actuators i.e., 4 vertical, 4 horizontal. Swivel mounting at both ends isolate the piston from side loads.
