Influence of Mechanical Vibration on Strain Gauge Based Force Transducer Performance

摘要

This paper deals with the influence of mechanical vibration on the performance of strain-gauge based force transducers. Force transducers of beam bending with binocular type were used for investigations. The transducers with different capacities varying in the range of 3 ― 30 kg were loaded by the calibrated masses and excited by discrete accelerations levels at a certain frequency. The difference in electrical output of transducer caused by mechanical vibration has been determined. Resonance curves of the transducers have been obtained by frequency sweep measurements under loaded conditions.
