Pcb Piezotronics, Inc. Meets Onera Requirement

PCB PIEZOTRONICS, INC. MEETS ONERA REQUIREMENT pcb.com | 1 800 828 8840 PCB Piezotronics, Inc. meets ONERA requirements ONERA’s Department of Aeroelasticity and Structural Dynamics has a crucial mission to conduct vibration testing on aircraft floors. Several hundred accelerometers are used in this procedure and ONERA chose PCB Piezotronics sensors for the job. Beyond simple reliability, measuring range and accuracy, PCB was selected based on their ability to deliver a product that met the environmental requirements in ONERA’s specifications. - ONERA, a French National Aerospace Re largesearch capacity Center, foris the testing top name in Europe in its providingfield. It is a multi-disciplined organization with a Aeroelasticityexpertise to program and Structural agencies, Dynamics institutions has fortyand industrial large and services. small-sized The vibration Department exciters of to meet industrial demands from companies such as Airbus, Dassault, Eurocopter and Snecma. - Floor vibration testing on an A320 Neo in Toulouse. PCB Piezotronics accelerometers are used for vibration measurements. tures sensors that measure physical values PCB Piezotronics, Inc. designs and manufac (vibration, force, strain, pressure and acoustics). For many years PCB® has provided technical solutions that meet ONERA’s requirements and comply with their environmental specifications. PCB® remains a partner with Onera for new projects. “Since 1972, we have conducted floor vibration testing on all the Airbus planes built in Toulouse.- The last three to date include the A380 in 2005, the A350 in 2013 and the A320 Neo in 2014”, reports Stephane Giclais, Project Manager for the Experimental Structural Dynamics Depart ONERA,ment. a major partner for Airbus, Dassault, Snecma and Eurocopter better calculate or predict mechanical stress behavior in unstable aerodynamic aircraft simula- One departmental objective is a focus on structural dynamic behavior prediction methods, to tions (vibratory).

Model validation requires hundreds of ac celerometers (from 500 to 800 on an Airbus), signal conditioners and a data acquisition system Testingthat features time a post-processwas successfully approach reduced to evaluating by 20% the due measured to ICP® vibration. and TEDS sensor technology from PCB Piezotronics. - The data acquisition system is designed to read the TEDS (transducer electronic data sheet) in increasedformation reliabilityand this eliminates and faster manual installation entry of of hundreds the accelerometer’s of accelerometers calibration needed information. for the test This mitigates the risk of data entry errors. ICP® and TEDS technologies contribute to simplification, series, while reducing the time needed for configuration checking. “With the same demand for test data, there is a 20% decrease in test installation time”, says Stephane Giclais. This meets the expectations of aeronautical designers, who need test data to validate their digital models quickly, and to verify hypotheses prior to the first test flight. “In only a few years and with increasing technical specifications and size of airplanes, test durations have gone from approximately three weeks down to about one week; all while delivering more information and detailed data analysis to the design engineers”, concludes Pascal Lubrina.
