6 Modelling of Operational Cycle in a Hydraulic Drive Based on Adjustable Axial Piston Hydraulic Machines

Direct Driven Hydraulic Drive

Hydraulic systems are widely used in industry because of the advantages of their small size-to-power ratios and their ability to produce very large linear force and torque. There are tendencies for compact electro-hydraulic systems which deliver powerful, linear movement having hydraulic oil circulation only when operating. This paper investigates directly driven hydraulic setup for non-road mo...

Mathematical Modelling of a Hydraulic Accumulator for Hydraulic Hybrid Drives

Modeling of hydraulic axial piston pumps including specific signs of wear and tear

Reliability of machines and facilities has played an important role since many years. Nowadays, attention is also paid to maintenance times. Maintenance standstills are to be reduced as far as possible. On the other hand, technical systems are subject to signs of wear and tear which are in general growing slowly and imperceptibly. The gradual abrasion of applied tools may lead to poor productio...

Monitoring the Condition of Loaded Modern Water Hydraulic Axial Piston Motor and Cylinder

Recent advancement in technology has produced materials that can withstand highly corrosive environment and lubrication-free materials for water hydraulic components. With precision machining becoming possible, very close tolerances can now be achieved to reduce internal leakage due to the low viscosity of water. Many industries are slowly but steadily turning to water hydraulic systems to repl...

Hydraulic Remotely Adjustable Pulmonary Artery Banding

Each year approximately 2000 children are born with a form of congenital heart disease that would benefit from mechanical restriction, or banding, of the pulmonary artery. [1,2] Installing or changing the setup of the banding requires an open chest surgery and during the first 6 months of the patient’s life, physiological parameters evolve rapidly, resulting in need for frequent reoperations. M...
