Summary
This Special Issue aims to provide a comprehensive platform for disseminating cutting-edge research across the full spectrum of fluid power transmission, with a particular emphasis on the synergistic relationship between system architecture and material innovation. We recognize that the distinct physical mechanisms governing hydrostatic precision, hydrodynamic efficiency, and hydro-viscous interface control present unique material science challenges and opportunities.
We invite original research articles and comprehensive reviews that address the following sub-topics, particularly those bridging mechanical engineering and fluid-dynamics with tribology, surface science, and advanced materials:
1.Hydrostatic Transmission Systems
Advanced digital hydraulic components (pumps, motors, high-response proportional/servo valves); Energy-efficient architectures: Electro-hydrostatic Actuators (EHA), independent metering systems, and hydraulic hybridization; Intelligent control algorithms and model predictive control (MPC) for hydraulic manipulators. Material-Focused Directions: Advanced Tribo-materials, Sealing & Elastomer Science,Surface Engineering, etc.
2. Hydrodynamic Transmission Systems
Advanced design optimization of torque converters and fluid couplings using CFD; cavitation inception, prediction, and suppression in high-speed hydrodynamic devices; multiphase flow and thermal management in high power-density hydrodynamic retarders; and material-focused directions, including cavitation erosion-resistant materials, additive manufacturing (3D printing), and lightweight materials.
3. Hydro-viscous Transmission Systems
Thermo-elastic-hydrodynamic lubrication (TEHL) modeling in hydro viscous clutches and wet clutches; Friction material degradation mechanisms and oil-film squeeze dynamics during engagement; Optimization Design of HVC Friction Pair Based on Thermal Solid Coupling Effect; Advanced control of Hydro-viscous Drive (HVD) for soft-start applications in heavy machinery; Material-Focused Directions: Friction Material Development ,Thermal Interface Materials, etc.
