Additive manufacturing is becoming more popular in the rapid prototyping of sensors, even for force transducers like load cells. These transducers are largely used in static or quasi-static measuring but their dynamic performances are of a certain interest too. Therefore, the enhancement of their dynamic properties is getting higher and higher attention. In this paper, an improvement in the dynamic characteristics of a strain gauge load cell is proposed with the redesign of the force transducer relying on additive manufacturing possibilities. The response characteristics of the force transducers built with both additive and conventional manufacturing methods are evaluated by analyzing the frequency response function estimated with an impulsive method. Dynamic parameters from both transducers have been evaluated and compared. The possibilities offered by the additive manufacturing technology led to an increase in the measurable frequency band of the considered transducer.

Abstract
Additive manufacturing is becoming more popular in the rapid prototyping of sensors, even for force transducers like load cells. These transducers are largely used in static or quasi-static measuring but their dynamic performances are of a certain interest too. Therefore, the enhancement of their dynamic properties is getting higher and higher attention. In this paper, an improvement in the dynamic characteristics of a strain gauge load cell is proposed with the redesign of the force transducer relying on additive manufacturing possibilities. The response characteristics of the force transducers built with both additive and conventional manufacturing methods are evaluated by analyzing the frequency response function estimated with an impulsive method. Dynamic parameters from both transducers have been evaluated and compared. The possibilities offered by the additive manufacturing technology led to an increase in the measurable frequency band of the considered transducer.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
