This paper describes the behavior of a rolling piston in a rolling piston type rotary compressor under various operating conditions. Kinematic behavior of the rolling piston is discussed with attention to the friction forces acting on the rolling piston and the vane. Emphasis is on the following simulation approach. (1) The equation of motion of the rolling piston is solved in conjunction with ...

Abstract This paper mainly studies the tribological performance of friction pairs and poor lubrication during piston movement. Based on average Reynolds equation comprehensively considering variable viscosity density characteristics lubricating oil, a transient hydrodynamic model ring-cylinder liner pair is established. By solving established model, oil film thickness value, value other paramet...

In this paper a mathematical simulation of a simplified internal combustion engine is presented. To contribute engine kinematics and its geometry, simple relations are derived for constrained motions. The equation of motion for the piston forms a singular boundary value problem. The uniqueness of the solution was studied in the Banach space. For solving governing equations an iterative numerica...

Based on the principle of hydrostatic bearing, in this study, several novel kinds of pistons were designed out, and the mathematic model of hydrostatic bearing on piston was established and analyzed. It was also found that, the diameter of damping hole and the width of pressure recess had impact on the radial load capacity of piston, the overall efficiency of axial piston motor, and the frictio...
