electric actuators shaking table

The shaking table is configured to produce three translational components of motion; vertical and two horizontal, plus three rotational components; pitch, roll and yaw. These six degrees of freedom can be programmed to reproduce any wave forms within the capacities of force, velocity, displacement, and frequency of the system. The shaking table can subject structures, weighing 100,000 lbs, to horizontal accelerations of
