Modeling and Characteristic Analysis of a Cylinder Block/Valve Plate Interface Oil Film Model for 35 MPa Aviation Piston Pumps

Machines, 2022
Oil film characteristics are critical to the high-reliability operation of high-pressure aviation piston pumps (APPs). However, there is still a lack of research on oil film modeling and characteristic analysis of high-pressure APPs. This paper takes the

Computational Investigation of Oil Film Pressure Profile in Journal Bearings [PDF]

Port-Said Engineering Research Journal, 2018
Lubrication of journal bearing in ship shafting systems is facing a problem in the slow speed range, where oil film created pressure depends on shaft speed, among many other factors. Hence, the slower the speed the lower the pressure will be, which shifts lubrication from hydrodynamic to boundary one. An experimental journal bearing test rig (JBTR) has

Research on the conversion method between the maximum oil film pressure and the measuring point oil film pressure of the tilting pad journal bearing

Journal of Physics: Conference Series
Abstract Currently, in order for the Chinese naval forces to achieve strategic transformation and move towards the deep blue sea, there is an urgent need to enhance the capabilities of far-sea operations. Most naval ships in various countries use gas turbines as the power source, and the bearings supporting the transmission shafts of gas

Dynamic Behavior of Oil Film between Piston Ring and Cylinder Liner : Visualization of Oil Film Rupture and Measurement of Oil Film Pressure Using Simulating Rig

JSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1995
In order to clarify the behavior of oil film between a piston ring and cylinder liner, pressure measurement and visualization of oil film are carried out simultaneously using a simulation rig. In this rig, the piston ring is simulated by a straight glass bar test piece and the cylinder by a reciprocating flat plate.

Deep hole connector design and oil film pressure study

Vibroengineering Procedia, 2023
Aiming at the problem of insufficient rigidity of the tool system and unbalanced radial force during deep hole machining, this paper designs a deep hole connector using the fluid dynamic pressure lubrication principle. The deep hole connector includes double-bridge strain gauges and tiltable tiles, which can increase the rigidity of the tool system by ...
