Optimal Design of Air Dampers Applied on Wash Mechines

공기감쇠기의 최적설계와 세탁기에의 응용

Air damper has a great advantage that is independent of temperature change. This paper presents an analysis approach and an application for designing nonviscous air damper with a piston and a cylinder. The objective functions for optimum design is damping coefficient and is maximized by changing two design variables that are length between piston and cylinder and orifice diameter. A digital computer program was developed which determines optimal air damper configuration for maximum damping coefficients. The results were applied to the automatic washer and are confirmed to be valid for the range of operating conditions.
