1. Tribology of hydraulic motor
Abstract : A radial piston hydraulic motor has several components involving sliding or rolling interfaces which may encounter tribological problems. Seizure is one of them and it results in complete stoppage of motion between the relatively moving components and has serious consequences in terms of the operation of a hydraulic motor. READ MORE

2. Numerical and experimental study of performance of a hydraulic motor
Abstract : The aim of this study was to develop an understanding of the fluid properties that influence the efficiency of hydraulic systems in a steady-state, especially components in hydrostatic transmission systems under different running conditions. The aim has also been to investigate and model the sources of losses in hydraulic machines, in order to estimate the losses, taking fluid properties into account. READ MORE

4. Investigations for enhanced tribological performance of a hydraulic motor
Abstract : A radial piston hydraulic motor has several components that encounter sliding orrolling motion under lubricated conditions. When a hydrostatic, hydrodynamic orelastohydrodynamic oil film separates the interacting surfaces, the wear and frictionare low provided of course the hydraulic fluid is free from the presence ofcontaminants.

5. Flow Pulsations in Fluid Power Machines - a Measurement and Simulation Study
Abstract : Stricter requirements for better working environment involve noise and vibration control of hydraulic machines. The operational conditions for hydraulic machines, such as pressure and rotational speed, are also increasing and this makes it even more difficult to develop a quiet, vibration-free machine due to the interdependence between noise and escalating operational conditions.
