Rotary Motion is a constant elliptical motion trajectory.
The shaking table is attached to the eccentric bearing. When the eccentric bearing rotates under the drive of the motor, the entire plane of the test platform will cyclically move in the upper, front, lower and back directions to draw an elliptical trajectory, which is also similar to the up and down trajectory of a horse’s body when it is running.
When the operator adjusts the speed of the rotary motion, it is equivalent to adjusting the traveling speed of the entire vehicle or ship.
