The parameters affecting the gravitational potential energy are the mass and the height of the object, the parameters affecting the elastic potential energy of the spring are the elastic modulus and the stroke, and the parameters affecting the kinetic energy of the flywheel are the rotating speed and the moment of inertia. To simulate mechanical energy in various life and production, a variable parameter experiment platform is needed to simulate the existence of mechanical energy in different sizes in various life and production.

At present, experiments are carried out indoors, needed equipment is short and exquisite, operation is convenient, if the equipment is too large, the experiments are inconvenient to carry out, and storage space is increased. The existing potential energy recovery experiment is that under the condition of ensuring a certain travel, a gear and a rack are matched to complete the travel, and the experiment can be completed only if the travel is certain and the length of the rack is at least not smaller than the travel due to the fact that the gear is at least one gear, when the rack is displaced to the highest point of the equipment in the experiment, the rack protrudes out of the equipment due to the length of the rack, the whole height of the equipment is increased, the increased height of the equipment is equal to the displacement height of the rack, so that the indoor experiment is inconvenient, when the rack reaches the designated height, the motor is closed, the sliding block is increased due to the action of gravity, the sliding block is accelerated, and huge impact is generated too fast when the speed is increased, so that the device is damaged. The damping effect of the rotary damper on the market is unstable, the provided reaction force change interval is small, however, the linear damper cannot travel a large stroke, and the problem is solved by utilizing the cooperation of the ball screw and the hydraulic cylinder type damper.

When the second rack 423 completes a certain stroke on the guide rail upright post 42, since the second rack 423 has a length, when the second rack 423 moves to a certain height of the guide rail upright post 42, the length of the second rack 423 protrudes from the upper end of the guide rail upright post 42, the height of the whole device is increased, when the shorter second rack 423 is used, when the certain stroke is completed, the shorter second rack 423 does not protrude from the device or protrudes less from the height of the device, when the longer second rack 423 is used, the upper end of the device is protruded, and the height of the device is increased more, when the two also reach the highest point of the guide rail upright post 42, the height of the device protruding from the shorter second rack 423 is shorter, and the height of the device protruding from the longer second rack 423 is longer; according to the invention, the second racks 423 are driven to move by the plurality of second gears 446, so that the shorter second racks 423 can complete the same stroke, and the height of the equipment is greatly shortened; and the damping mechanism 45 ensures that the second sliding blocks 422 with different weights can still stably descend at the time of sliding down, so that the device is not damaged due to huge impact generated by the excessively high speed.
By arranging the damping mechanism 45, when the initial speed of the second sliding block 422 at the upper end of the device is 0, the reaction force of the damping mechanism 45 is close to 0, as the reverse moment generated by the gravity action of the second sliding block 422 on the first transmission shaft 442 acts on the third motor 441, the action of the damping mechanism 45 on the first transmission shaft 442 is correspondingly increased when the speed is increased, the damping mechanism 45 ensures that the second sliding blocks 422 with different weights can still stably descend when sliding downwards, and the device is not damaged due to huge impact generated by the excessively fast speed.
