Optimize dynamics and acoustics in RnD
The actual deflection shapes and resonant frequencies due to stiffening effects at high RPM are measured and can be taken into account in the validation process of FE models. By means of the Optical Derotator order analysis and vibration measurement become feasible in a simple manner. Telemetry systems become unnecessary. Sophisticated control electronics track the motion of the rotating object, resulting in a steady position of the laser beam. The actual measurement is astonishingly simple. Due to the synchronized speed of the derotator the object appears to stand still.
The PSV-A-440 Optical Derotator is supplied either as an add-on for a Polytec scanning vibrometer or as a complete solution comprising the rotating unit with encoder input, a control unit, an adjustable base frame for angular and height adjustment, a VibroScan QTec Neo Scanning Vibrometer and a single-point reference vibrometer. A software module installed on the Data Management System of the scanning vibrometer allows easy configuration of the derotator for dynamic run–up tests and static tests.
