사판식 유압 피스톤 펌프의 피스톤과 실린더 사이의 윤활해석

The thin film flow in the clearance between the piston and cylinder is numerically analyzed to study the lubrication characteristics of the Swashplate type axial piston pumps. The Reynolds equation is solved using a finite difference method under Reynolds boundarycondition. The pressure distributions in the clearance and the lateral forces acting on the piston are compared for various operating conditions. Tilting and rotation of the piston in the cylinder gore are highly affect the lubrication characteristics, therefore, additional analysis are required.
