Ten Tips to Optimize Servo Hydraulic Machines for Long Term Productivity

Performing pre-emptive, scheduled maintenance is the key to not only extending the life of your machine but also reducing downtime and ensuring quality parts are delivered over the long term. Long-term productivity can also be enhanced by decisions made by the OEM when a machine is in the design phase. This article discusses ten tips that are useful for both machine builders and machine owners to know about optimizing servo-hydraulics. Full Article

Hydraulic motion control puts Formula 1 performance on a whole new track

Fans attending the US Grand Prix in Austin on November 2nd, 2014, witnessed a completely new breed of Formula 1 car. Their first impression might have been the unfamiliar sound of quieter lower-revving cars, which has caused much controversy amongst ‘die-hard’ F1 fans. While appearing superficially similar, this year’s F1 cars are dramatically different under the skin. This is due to evolving technical regulations that encourage F1 designers to focus on new technologies that are more relevant to road cars—including techniques to improve fuel efficiency.

Safer Landings Start With Smarter Servo Valves

In 2009 the engineers from Airbus’ High Lift Test Centre in Bremen, Germany needed a system to test the landing flap systems for the new Airbus A350 airplane. The new Airbus A350 has two landing flaps at each wing that are stressed by high aerodynamic forces. These forces need to be simulated during the test. Full Article

Steady Under Pressure: Undersea Exploration Benefits from Moog Innovation

One recent trend in the industry is the installion of increasingly complex and sophisticated equipment on the seabed, for oil and gas exploration and production. This requirement presents a unique challenge, as extremely heavy mechanical structures have to be lowered to the seabed by winches or cranes from floating vessels which are subject to wave motion. A key technique to achieve this is 'Heave Compensation' where the vertical movement of the vessel is electronically monitored and the crane/winch is automaticaly controlled to compensate for this. Effectively the crane cable is continuously paid out or reeled in to allow the load to "hover" above the seabed. The operator of the winch can then generate command signals to the winch drum which are superimposed on the automatic compensation function. This permits the operator to precisely control slow and accurate movements - relative to the seabed. Full Article
