The ring shaped force transducers are widely used in practice and are available in varying capacities from few hundred newtons to mega newtons. The present paper discusses the deflection studies of thering shaped force transducers under action of axial forces. Various methods leading to the measurement of deflection have been discussed and compared here.

    ABSTRACT: In this paper, the analysis of octagonal ring type transducer has been carried out by considering some basic elastic theory of thin circular ring. Using those transducers, a drilling dynamometer was designed and constructed to measure drill cutting forces: thrust and torque. In the dynamometer, strain gages mounting places were indicated clearly on the transducers by appreciating characteristics of the strains due to drill forces. The wiring diagrams of the strain gages of dynamometer were illustrated separately for the forces to be measured. The rigidity of the dynamometer was also analysed considerably in detail by determining natural frequencies in vertical and torsional modes to avoid resonance. After having completed the construction of it, the dynamometer was tested by performing drilling and measuring the forces, thrust and torque, on SAE 1020 steel. The results were compared to similar works to show the performance of the constructed dynamometer. Complete construction drawings of the dynamometer were also presented to researchers of metal cutting.

    ABSTRACT: The thesis proposed in this lecture is that solutions given by design equations representing the behavior of a structure or body will give the best approximation if an integral use is made of theoretical and experimental stress-analysis methods. To demonstrate the validity of the thesis, an investigation is described concerning a ring-shaped elastic element used to measure a force by relating it to diameter variations or to inner and outer surface strains.To attain this goal, analytical, experimental (strain gages and photoelasticity) and numerical (finite-element) methods were used. The results obtained were investigated through an analysis of the acting nominal force and the influence quantities, namely, force components, parasitic components and interactions of the transducer, testing machine and measurement instrumentation.Other experimental results based on a statistical analysis were found to make the actual behavior of the elastic element clearer, also they approximate closely the solutions given by design equations.
