An air damper has a great advantage in that it is independent of temperature change. This paper proposes an analytical approach for designing an air damper with a piston and a cylinder. The characteristics of the air damper depend on the properties of air: viscosity and compressibility. Thus, the air damper shows the so-called visco-elastic property: the applied force to the piston is resistant to the velocity and displacement of the piston. As a result, the air damper has two important factors: the damping coefficient and the spring constant. Two types of air damper are discussed. Type I is a viscous damper whose resisting force is proportional to the piston velocity, and type II is a nonviscous damper whose resisting force is proportional to the velocity-squared of the piston. The present analysis was well explained by the experimental evaluation of the damping coefficient and the spring constant of the air dampers. This paper leads to a simple and accurate method for designing an air damper.
