Single Axes Shake Tables

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

The tables are designed with natural frequency to exceed 100Hz and the design ensures the c.g of the test object can be anywhere within the table and elevated up to 1000mm above the table. Precision machined rails engage with the linear bearings and provide linear horizontal movement.
