Abstract: The present invention discloses a modular structure for fixing radial electromagnetic actuators for non-destructive tests and failure simulations in rotating machines without disassembly of bearings and comprises the following components: ferromagnetic core (1), armature (4), cover (6), load cell (10), upper reinforcement (15), lower reinforcement (16), lower plate (17), side plate 1 (18), side plate 2 (19), upper plate (20), beam (7), spool (2), adjustment 1 (11), captive pin (3), chassis (5), lock (8), plate (9), adjustment 2 (13), captive screw (12), adjustment 3 (14).

Abstract: A method to acquire the structural health state of an aircraft mechanical component performs measurements at each frequency point of interest by using a network of transducers and working each one simultaneously as actuator and sensor. Each transducer is individually excited by a sinusoidal, constant frequency and arbitrary amplitude, voltage waveform for each arbitrary frequency point used to interrogate the structure. A dedicated hardware executes an analogical (analog) quantization to measure electrical current and average electrical power consumed by each transducer. With these two variables, the electromechanical signature of the structure is obtained at different areas of the monitored structure.
