Efficient, Integrated, Freeform Flexible Hydraulic Actuators—Additively manufactured, flexible, fluidic actuating systems that exhibit an order of magnitude higher specific power than existing systems and maximize system efficiencies through model-based optimal control will be developed.
Four-Quadrant Multi-Fluid Pump/Motor—This project will develop a high-efficiency, mechanically controlled, four-quadrant pump/motor capable of pumping oil, water, and corrosive fluids.
Hybrid MEMS (Microelectromechanical Systems) Proportional Fluid Control Valve—Extremely efficient pneumatic proportional valves will be created by exploiting piezoelectric technology.
Portable Pneumatically Powered Orthoses—This project will drive the development of enabling fluid power technologies to miniaturize fluid power systems for use in novel, human-scale, untethered devices in the 10- to 100-W range.
Investigation of Noise Transmission through Pump Casing—This project will model the transmission of the vibrations from a swashplate-type axial-piston pump through the pump’s casing to the generation of acoustical noise in the surrounding environment.
Control and Prognostics of Electrohydraulic Machines—The control approach for load handling hydraulic machines that combine oscillation damping features with system prognostic functions will be formulated.
Free-Piston Engine Based on Off-Road Vehicles—The design, control, and testing of a hydraulic free-piston engine will be investigated for off-road vehicles to improve fuel efficiency and reduce emissions.
Controlled Stirling Power Unit—This project will develop a completely silent, high-energy, dense, and portable fluid power supply using a Stirling device.
