가스 스프링 Elevation 동작 마찰력 보상 연구(2) -관형 오리피스 단면 및 피스톤 로드의 부피 보상 장치 A Study on the Elevation Motion Friction Compensation in Gas Spring(2)-Cross Section of Pipe Type Orifice and Volume Compensation Apparatus of Piston Rod
pp.721-728
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 specification decision and volume compensation experiment as an apparatus for compensating of the volume of the cylinder is compressed as the volume of piston rod. 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 total consideration in stability problem and performance of volume compensation for specification decision and volume compensation experiment is determined the final speculation of hollow rod φ8×φ4 and riveting system.
