Abstract
News editors obtained the following quote from the background information suppli ed by the inventors: “Servo-hydraulic material testing machines (also sometimes known as structural tests machines) are used to test the physical characteristic s of a material sample by utilising a hydraulic actuator to apply a test force t o the material sample.The hydraulic actuator is driven by a hydraulic power uni t which is typically arranged to provide pressurised hydraulic fluid to the mate rial testing machine.“However, existing hydraulic power units used for material testing applications operate inefficiently and give rise to an excessively high power consumption.
