[0068] The present invention takes the following four suspension devices as examples to illustrate the specific implementation of the passive zero-stiffness suspension device based on the zero-frequency vibration isolation theory:
[0069]Technical solution 1: Double vertical slide rail long-axis passive zero-stiffness suspension device
[0070] like figure 1 As shown, the suspension device includes two horizontal elastic elements 1, two vertical slide rails 2, mass blocks 3, horizontal slide rails 4, two connecting rods 5, two vertical slide blocks 6, two horizontal slide rails Block 7, vertical elastic element 8 and vertical guide rod 9.
[0071] One end of each horizontal elastic element 1 is fixedly connected with the foundation, and the other end can only move along the corresponding horizontal slideway and the two horizontal slideways are on the same horizontal line; the free end of each horizontal elastic element 1 is connected with a connecting rod 5 One end hinged; ...
