Performance Improvement of a Two-Stage Proportional Valve With Internal Hydraulic Position Feedback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present research concentrates on the performance improvement of a two-stage proportional valve with internal hydraulic position feedback which is named as the Valvistor valve. In this paper, the performance constraint ...
Stiffness and Damping Properties of (Semi) Floating Ring Bearing Using Magnetorheological Fluids as Lubricant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Magnetorheological fluids (MRFs) are applicable for achieving semi-active control in smart bearings. For hydrodynamic bearings lubricated with MRF, changes of the viscosity induced by magnetic field lead to changes of the ...
A Novel Control Strategy for Pilot Controlled Proportional Flow Valve With Internal Displacement-Flow Feedback
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present study is focused on the construction of a well-performing pilot controlled proportional flow valve with internal displacement-flow feedback. A novel control strategy for the valve is proposed in which the flow ...
Rotor Dynamics Behavior of Tilting Pad Bearing Supported Turbo Expander Considering Temperature Gradient
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper dedicates on the rotor dynamics behavior analysis on a tilting pad bearing supported turboexpander rotor system considering temperature gradient. Both numerical and experimental investigations are conducted ...
