Three-Axes Seismic Shake Table (SH-04-XXXX)

BiSS 3-axes, 6 Degree-of-Freedom shake tables are state-of-the-art solutions for vibration and seismic studies, including earthquake simulation, soil liquefaction, fluid-structure interaction, dynamic structural response and component and damper assessment for vibration and earthquake resistance. Practically any multi-axis acceleration-time history can be faithfully reproduced on the system within the envelope of its technical specifications. This can range from harmonics to 6-axes acceleration records of actual earthquakes.

 

 

 

Standard Features
• Simulator tables, 0.5 x 0.5 m, 1 x 1 m, 2.5 x 2.5 m and 3 x 3 m
