SH-03-00XX Three Axis Shake Table

BiSS 3-axes, 6-degrees-of-freedom shaking tables are state-of-the-art solutions for seismic simulation, soil liquefaction and vibration tests on building models as well as for engineering qualification of equipment or its components and assemblies for earthquake and vibration resistance. The table is designed to enable rigid mounting of specimens for transfer of required acceleration history. The center of gravity of the test object can be located anywhere within the working space of the table. 

Table motion is generated through precision dynamic synchronous control of all 8-actuators: 4-vertical, 4-horizontal. The double ended, double acting, equal area servo actuators with swivel mounting on both ends isolate the piston rods from side loads.

The system is powered by an electronically servo controlled low noise, variable flow, variable pressure, energy efficient pump and a digital control and data acquisition system with options to connect a wide variety of transducers.
