The invention relates to a mine explosion-protective suspension-type damper with a single-stage damping structure. Vibration isolators at the bottom are used for attenuating most major impact generated by explosions. Through compression deformation of the vibration isolator, energy is absorbed in order to attenuate impact. Therefore, huge impact transmitting from a car body is attenuated within the short period of time. After explosion impacts upon a military vehicle or a vessel are secondarily attenuated, impact values transmitted to the neck, the lumbar vertebra, the abdomen, knee joints andother parts of a passenger body from a seat are all within the scope of limiting values accepted by human bodies. The mine explosion-protective suspension-type damper is easy to produce, manufacture,use and maintain and can effectively guarantee life safety of commanders and fighters.
