The base 1 is the foundation of the whole composite damping device and bears and transmits external vibration.
The vibration isolation rubber sleeve 3 and the first spring 4 are arranged to realize primary vibration absorption and absorb part of vibration energy, and the first limit column 5 and the second limit column 6 respectively play a role in guiding the up-down displacement direction of the carrying platform 2 and the base 1, so that the situation that the carrying platform 2 or the base 1 is separated from the vibration isolation rubber sleeve 3 and transversely displaces due to the elastic action of the first spring 4 when the vibration energy is absorbed is prevented.
Converting the vibration energy into elastic potential energy by the third spring 9;

when vibration is applied to the base 1, a part of energy is firstly absorbed by the vibration-insulating rubber sleeve 3 and the first spring 4, and the rest of vibration energy is stored by the third spring 9, so that the lower pressing block 10 moves upwards and collides with the upper pressing block 8 above the lower pressing block. Depending on the specific situation of the collision, two different energy conversion modes can be generated:
In the first case, the upper press block 8 and the lower press block 10 move upwards together, and then the upper press block 8 compresses the second spring 7 until the kinetic energy of the upper press block is completely converted into the potential energy of the second spring 7, and the upper press block 8 obtains the kinetic energy and moves back along with the release of the potential energy by the second spring 7 and collides with the lower press block 10 again;
