D1.3 - Multi-sensor system for dynamic deformation and vibration measurements at high-speed rotors
Abstract
he in-situ characterization of the material behavior of glass-fiber reinforced polymer (GFRP) disc rotors under dynamic load is an important step towards the development of novel, lightweight materials for several applications, e.g. the aerospace industry. However, the dynamic rotor behavior is complex and difficult to determine. In order to develop improved models and simulation techniques for the optimization of composite materials, the deformation of rotors under dynamic load has to be investigated. A four component multi-sensor system is applied for in-situ monitoring of the dynamic rotor expansion. A novel signal processing algorithm is used to take tumbling motion into account, which previously restricted the precision of radial expansion measurements. As a result, micron precision for the angular resolved rotor expansion is achieved at temporal resolutions of only one rotor revolution, corresponding to an increased precision of the rotor expansion by a factor of three to six over the state-of-the-art approach. Eventually the mean rotor expansion in dependency of the rotational speed is determined with submicron precision.
