Flexible Equipment for a Varied Range of Measurement Tasks
For the fuselage shell test, IMA Dresden is commissioning a test bench that has been developed from scratch. The design of the servo-hydraulic test bench is a proprietary development borne out of extensive in-house experience, as Gerd Striegler, Head of Measurement Technology at IMA Dresden, explains: “The modified design makes the test bench more flexible for different tests, component dimensions and test standards.” What’s more, several types of stress can be exerted simultaneously and tested in a realistic manner.
The new test bench uses about 30 hydraulic actuators with suitable HBK force transducers, so that it can simulate motion-related tensile, compressive and shear stresses. The reactions to these are measured by 500 strain gauges applied on the test specimen. To achieve this, IMA Dresden relies fully on the QuantumX data acquisition system from HBK for recording the strain gauge signals in various bridge configurations and digitally conditioning them for further processing.
QuantumX is a plug-and-measure solution with comprehensive support of TEDS (Transducer Electronic Data Sheet) technology, which enables fast and flexible adaptation of the test bench in whichever way is needed. The sensor characteristics of each individual sensor are automatically read out from the TEDS chip installed in the sensor or connector, and thus significantly reducing setup times when reconfiguring measurement tasks. Manual entries – frequently the cause of errors – are no longer needed.
