Abstract
The present investigation reports the development of a force transducer for industrial applications with facile design and manufacturing objectives. The design of the force transducer is based on the analytical and computational approaches, followed by the experimental verification. Factors such as stress, strain and deflection of the force transducer were evaluated while conducting a rigorous assessment of the proposed force transducer. Al 7075 (T6) grade of aluminum alloy has been used as the material for fabrication of the force transducer with a nominal capacity of 2 kN. The fabricated force transducer as per the proposed design has also been investigated for geometrical and dimensional accuracy using precision coordinate measuring machine (CMM). Metrological characterization as per ISO 376: 2011 revealed that uncertainty of measurements is within 0.05 %, which includes relative uncertainty of the force transducer the factors such as repeatability, reproducibility, reversibility, interpolation, resolution, zero offset. Based on the above investigations, it has been found that the designed force transducer is of low cost ($ 200–$ 300), ease to manufacturing, and precise enough (0.05 % uncertainty of measurement) force transducer for force measurement up to 2 kN. The developed force transducer offers sensitivity up to of 0.2 N or better.
Highlights
Measurement systems have followed instrumentation for the measurement of force
Force transducers are needed for critical force measurements of functional grip by novel force transducers [1] e.g., bio-mechanic transducers
The following conclusions may be drawn from the work presented here: 1) An square ring force transducer (SRFT) was designed based on analytical and computational approaches followed by experimental measurements
Summary
Measurement systems have followed instrumentation for the measurement of force. For the analysis of the stress, strain, and deflection, the similar equation applies in the development & characterization of a square ring shaped force transducer along with the role of stress analysis by the previous researchers [2], [24]. Such a force transducer offers simple manufacturing and design considerations.
