Abstract

Design studies of force transducers are important in optimization of their design for various applications including verification of material testing machines, monitoring force components in different cutting tools, agriculture related applications etc. Generally, some assumptions and approximations have been made for deriving analytical expressions for stress/strain analysis/axial deflection of force transducers. For more rigorous validation of analytical derived expressions, experimental and numerical methods (finite element analysis) have to be used. In the present study, a circular ring shaped force transducer, commonly used for force measurement, has been studied under axial forces, using finite element analysis and a comparison has been made between the results obtained by finite element analysis, analytically derived expressions and the experimental method for the axial deflection. It is observed that the results obtained using finite element analysis, are closer to experimental method as compared to the results obtained using analytical method. The computational error reported is about 3%, which represents the deviation between the values observed experimentally and computed using finite element analysis. The paper attempts to unearthen the possible reasons for the deviations between the different methods. In order to validate the findings, some preliminary results are also presented.
