Bi-axial Shake Table (SH-01-XXXXB)

BISS Bi-Axial Shake tables are ideal to perform seismic simulation, soil liquefaction and vibration tests on models as well as for engineering qualification of components and assemblies for earthquake and vibration resistance. The table is designed with a natural frequency to exceed 100 Hz and the design also ensures that the center of gravity of the test object can lie anywhere within the table and elevated up to 1000 mm above the table. The precision machined rails engage with the linear bearings and provide the linear horizontal movement in X and Y directions. 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. BISS systems are configured to specific client requirements, using many standard and available high quality industrial grade components.
