Laboratory of Adaptive Structures<img alt="" src="http://webtest.cira.it/PublishingImages/LASA.jpg" style="BORDER:0px solid;" />https://www.cira.it/en/research-infrastructures/laboratorio-strutture-adattive-(lasa)/Laboratory of Adaptive StructuresLaboratory of Adaptive Structures<p>From an operational standpoint, the LASA laboratory is able to mature, implement and validate different kind of demonstrators and prototypes as:</p><ul><li>Morphing systems;</li><li>Deployable systems;</li><li>Variable charcateristic systems;</li><li>Structural health monitoring systems (SHM);</li><li>Mechanical components monitoring systems;</li><li>Environmental monitoring systems;</li><li>Vibroacoustic control systems;</li><li>Vibration control systems;</li><li>Noise control systems;</li><li>Comfort enhancement systems;</li><li>Highly distributed sensor systems;</li><li>Sprayable sensor systems.</li></ul><p>Surveys range from static systems (shape control) to dynamic systems (dynamic response control, such as vibroacoustics) and use classical sensory systems (strain gauges, accelerometers) or innovative (piezoelectric, FBG, etc.) as well Such as classical implementation systems (linear, rotary, etc.) or innovative (piezoelectric, form memory alloys, etc.) configured in compact and minimally intrusive architectures. The monitoring and control systems used are based on the classic feedback and feedforward architecture, adapted to the peculiarities of the structural systems that require the displacement of a large number of transducers and actuators.</p><p>According to the ACARE Taxonomy, LASA operates inside the following domains:</p><ul><li>Miniaturisation of sensors (piezoelectric devices, optical fibers,..); </li><li>Integration of sensors; Single crystals; Active Piezoelectric materials; </li><li>Electrostrictive materials; Magnetostrictive materials; </li><li>Electrorheological and magnetorheological materials; </li><li>Shape memory alloys; </li><li>Multi-functional materials; </li><li>Actuator systems; </li><li>Micro-motors; </li><li>Control strategies; </li><li>Health monitoring systems; </li><li>Control of noise and vibration; </li><li>Shape control (morphing); </li><li>Active flow control; </li><li>UAV, mini UAV.</li></ul><p>The LASA laboratory has the following equipment:</p><ul><li>Workstation dedicated to structural design of technology demonstrators, the implementation of structural systems control logic and the implementation of multi-objective optimization processes;</li><li>High-voltage amplifiers for piezo-electrics (PZT);</li><li>Power supply for shape memory alloys (SMA);</li><li>Acquisition system for strain gauges, thermocouples, etc.  (Cronos);</li><li>OSA Optical Spectrum Analyser;</li><li>Optical Interrogator (Micron Optics sm130);</li><li>DSP for multichannel structural control (DSpace);</li><li>Optical and Mechanical tables for the experimental tests and the mock-up preparation.</li></ul><p>The available instrumentation is used for:</p><ul><li>Generation and amplification of signals;</li><li>Acquisition of deformations, displacements, stress, temperature, force and wavelengths related to the use of different functional materials (PZT, SMA, FO, etc.) and various standard sensors (strain gauges, load cells, thermocouples, accelerometers);</li></ul><p>Rapid manufacturing of demonstrators capability, as well as adequate support to the controlled verification of small embedded devices. </p><p>​The lab is involved in national projects (PON - PRNM) and European (H2020 - CS2), with varied partnerships (agencies, universities, research centers, SMEs, industries), among which the Universities of Naples and Rome, Politecnico di Milano and Turin, CNR, ASI, Leonardo FNM, Avio Colleferro, AIRBUS (D), DLR (D), ONERA (F), Siemens (B), UMBRA Bearings, Italsystem, Meggit (UK). There are also active contacts and cooperations with Penn State University (USA) and TsAGI (RUS).</p><p>Aerospace industries: (Leonardo FNM, AIRBUS, Umbra cuscinetti, Avio Colleferro, Telematic Solutions).</p>
