Abstract

This paper presents design and development of precision ring shaped force transducers (FTs) based on theories of thin elastic rings for uniaxial forces in compression and tension mode (capacity 20 kN and 50 kN). A three dimensional model of FT has been developed and stress - strain and axial deflection patterns have been studied using software ABAQUS standard student edition 6.7.2. FTs are metrologically characterized according to calibration procedure based on ISO 376-2004 using 50 kN dead weight force machine with uncertainty of measurement ± 0.003% (k = 2). FTs are found to have uncertainty of measurement better than ± 0.025% (k = 2) including relative deviations due to repeatability error, reproducibility error, zero error, resolution error, interpolation error and uncertainty of measurement of force applied. FTs qualify class 00 per the standard ISO 376-2004 and may be used as force transfer standards.
