Hydraulics in Testing

Wednesday 25 September 2013, Star Hydraulics, Tewkesbury

This highly successful one day event was held at Star Hydraulics, Tewkesbury and was attended by all levels of engineers involved in the design, use or maintenance of servo-hydraulic testing systems.

In the morning session the main elements of a servo-hydraulic system were reviewed including high pressure pumps, oil filters, oil coolers, high pressure oil delivery systems, hydraulic actuators and servo valves. The importance of maintaining cleanliness in an oil system was discussed, including a description of oil filtration systems, the need for oil filtration and best practice in the maintenance of oil systems.

The importance and process involved of specifying the correct servo-hydraulic actuator for a specific test, both in terms of performance and energy consumption, was reviewed including the determination of the mean and peak oil flow requirements and servo valve specification.

Delegates especially enjoyed the tour of the servo-valve manufacturing facility.

After the tour there was a presentation describing servo-hydraulic actuator control systems, including adaptive control systems used for real-time simulation and gain control configuration. The importance and process involved in setting the actuator control feedback system for optimum response was outlined.

At the end of the presentations there was a forum, comprising a panel of experts, where there was be the opportunity for attendees to raise questions on any aspects of the subjects covered during the day, or to raise questions in general about servo-hydraulic test systems for advice or that require a solution.
