가스 스프링 Elevation 동작 마찰력 보상 연구 - 오리피스 형태에 따른 성능 규명 A Study on the Elevation Motion Friction Compensation in Gas Spring – Performance Investigation according to Orifice Shape
pp.841-846
In this study, factors analysis is performed for reducing friction in elevation motion of a large television stand over 50-inch. The first is a pipe type cross-section control for accurate position control of the piston rod. Here it was compared with the pipe type and labyrinth type orifice cross-section. The second study is for optimized piston structure development by comparison pipe orifice and labyrinth orifice. Consequently, in the orifice cross section study between pipe type and labyrinth type through CAE and experimental consideration, cross section of labyrinth type orifice is preferred for reducing of friction. The result of optimized piston structure development through experiment is fixed orifice specification as labyrinth orifice because pipe orifice is founded slip up/down phenomenon of the Ø0.4~1.0 orifice and the labyrinth orifice is not founded that of the Ø0.4~0.6 orifice both tests on 300 mm intervals.
