An experimental device that utilizes a magneto-spring and collision forces for a single-degree-of-freedom stimulus is proposed. By way of an actuator, the experimental device that was created in order to test the response created by a magneto-spring stimulus force arising from an impact force, applies a displacement stimulus to the magnet on one side, changing the distance between the magnets as well as the faced surface area of the magnets. The moving mass that, which supports the loaded mass and the magnet on other side, provides kinetic energy via the actuator and the magneto-spring. When the moving mass impact on impact plate, the impact plate turn over the motion of direction. This collision stimulus device is composed of a mechanisms having low damping, and being vibration device using a magneto-spring, it was verified through analysis and experimental studies to be a highly efficient shaker mechanism. The relation between the inputs and outputs that use variations in the magnetostatic energy created by changes in the distance between the repulsed magnets and the faced surface area was verified by studying the amount of work created by the magneto-spring stimulus energy of a repulsed magnet system during one vibration cycle of the moving mass attached to a moving magnet and a fixed magnet.
