Overview. The Shake Table I-40 consists of a stage mounted on a high-quality, low backlash linear guide with a total travel of 40.0 mm and is driven using a ball-screw drive mechanism. Using the high torque direct drive motor, the stage loaded with a 1.5 kg mass can be accelerated up to 1.0 g. The high-resolution encoder enables the system to obtain a linear stage position resolution of 1.22 μm.
Overview. The Shake Table II XY consists of two single-axis Shake Table IIunits mounted perpendicularly on top of each other. Each stage can travel 7.6 cm. Driven by powerful motors, the Shake Table II XY can achieve an acceleration of 2.5 g when loaded with a 7.5 kg mass.
