Variable-pressure active liquid vibration isolation seat system

The invention discloses a variable-pressure active liquid vibration isolation seat system, belongs to the field of vibration control, and provides the variable-pressure active liquid vibration isolation seat system for passenger vibration isolation. The vibration isolation device can be installed on a passenger seat of carrying equipment, and the vibration isolation effect of transmitting carrierequipment to passengers is achieved. The variable-pressure active liquid vibration isolation seat system is mainly composed of a shear type suspension, a hollow seat body, an external variable-pressure device, a seat liquid vibration isolation device, a vibration isolator support and the like. By adjusting the external pressure of the hollow seat main body, the vibration isolation frequency and the vibration isolation efficiency of the seat liquid vibration isolation equipment can be changed, so that the vibration isolation range and the vibration isolation efficiency of the vibration isolation seat are better. 变压主动液体
