The flexible support columns 4 include a reset spring 41 and a rubber pad 42. The rubber pad 42 is fixedly bonded to one end of the reset spring 41. The reset spring 41 is bonded to one end of the rubber pad 42 and inserted into the top of the shockproof base 1. A plurality of positioning blocks are fixedly installed on the bottom of the simulation platform 3. The bottom of the positioning block is provided with a receiving groove corresponding to the flexible support column 4; the noise reduction enclosure 2 is sleeved on the top of the shockproof base 1, and the top of the noise reduction enclosure 2 It is mounted on the bottom end of the simulation platform 3, and the noise reduction enclosure 2 includes a first retaining ring 21, a second retaining ring 22 and a noise reduction sleeve 23. The first retaining ring 21 and the second retaining ring 22 are respectively mounted on the two ends of the noise reduction sleeve 23. The noise reduction sleeve 23 is made of woven PET silk thread. The inner wall of the noise reduction sleeve 23 is bonded with multiple layers of noise reduction cotton 5. The inner wall of the noise reduction cotton 5 is covered with a dustproof cloth 6. A plurality of air holes are provided on the noise reduction sleeve 23, and absorbent cloth is inserted in the air holes. The simulation platform 3 includes a fixed plate, a power controller and a vibration module. The vibration module is fixedly installed at the bottom center position of the fixed plate, and the power controller is arranged at a corner of the top of the fixed plate.

[0022] like Figure 1-2As shown, the shockproof base 1 includes a support plate 11, noise reduction feet 12 and a sealed shell 13.

[0023] Specific implementation process: The first retaining ring 21 and the second retaining ring 22 have a certain deformation ability, so the first retaining ring 21 and the second retaining ring 22 can be directly mounted on the top of the shockproof base 1 and the bottom of the simulation platform 3. The power controller and vibration module of the simulation platform 3 are used to control the amplitude and frequency of the fixed plate. Because objects will make noise when vibrating, the device uses flexible support columns 4 to set the main vibration components above the shockproof base 1 at intervals, avoiding the vibration of the simulation platform from being fully transmitted to the shockproof base 1, and reducing the vibration noise between the device and the workbench where the device is placed during the vibration process. The second part of the noise comes from the spontaneous noise of the vibration module of the simulation platform 3, so the noise reduction enclosure 2 is used to absorb and reduce the spontaneous noise of the vibration module, so that the device is easy to assemble and transport while also reducing the noise during the operation of the device, making it more convenient to use in places where academic achievements need to be reported, etc.
