Overview and Application Areas

When structures (bridges, buildings, etc.) are subjected to external shocks and vibrations such as wind and earthquakes, the silicone oil filled inside the cylinder will move quickly between the gaps around the piston. In this process, the friction between the silicone oil and the piston rod, the cylinder body, and the friction between the molecules of the silicone oil occur, resulting in a large damping force.
This damping force (α) dissipates the input energy applied to the structure by dissipating the mechanical energy transferred to the structure into the internal energy of the silicon oil and dissipating it as heat energy.
Here, the graph of the correlation between damping force and displacement is called the hysteresis curve.
The smaller the damping index of the relational expression that represents the damping force of a viscous damper, the higher the energy dissipation efficiency.
