Method for the contactless determination of forces and/or torques acting on a hollow cylindrical body and a measuring system for carrying out the method

摘要

The method involves generating light radiation in the interior of a hollow cylindrical body (12) by a light source (20), and recording the measured signals by an optoelectronic sensor (22). The measured signals recorded by the optoelectronic sensor are fed to a signal processing unit (26). The changes of the measuring signals are detected by the signal processing unit. An output signal is emitted by the signal processing unit by a mechanical deformation of the hollow cylindrical body corresponding to a calibration function or a computing instruction. An independent claim is included for a measuring arrangement for contactless determination of forces or torques acting on a hollow cylindrical body of a rotary-wing aircraft.
