PURPOSE: An apparatus for adjusting the lower stiffness of a deck house is provided to actively avoid resonance by reducing vibration response level while the natural vibration frequency of a deck house is adjusted by adjusting the lower stiffness of the deck house. CONSTITUTION: An apparatus for adjusting the lower stiffness of a deck house comprises a height adjusting controller(120), a cylinder(100), and a piston(110). The top of the height adjusting controller is fixed at the bottom of the upper deck. The height adjusting controller is fixed on the top of the cylinder in a sealed state. The cylinder is filled with fluid for generating hydraulic pressure. One end of the piston is connected at the bottom of the cylinder in a sealed state and the other end of the piston is fixed on a lower deck. |
