Force transducer have been designed on the basis of theories of thin rings and design plays an important role in various applications like verification of material testing machines, monitoring force components in different cutting tools, agriculture related applications, hardness testing machines etc. Generally, some assumptions and approximations have been made for deriving analytical expressions for stress / strain analysis / deflection of force transducers. For more rigorous validation of analytical derived expressions, numerical methods need to be used. In the present study, a ring shaped force transducer, commonly used for force measurement, has been studied using finite element analysis. The study provides scope for the effect of nominal quantities over the design of ring shaped force transducers.

Abstract


Force transducer have been designed on the basis of theories of thin rings and design plays an important role in various applications like verification of material testing machines, monitoring force components in different cutting tools, agriculture related applications, hardness testing machines etc. Generally, some assumptions and approximations have been made for deriving analytical expressions for stress / strain analysis / deflection of force transducers. For more rigorous validation of analytical derived expressions, numerical methods need to be used. In the present study, a ring shaped force transducer, commonly used for force measurement, has been studied using finite element analysis. The study provides scope for the effect of nominal quantities over the design of ring shaped force transducers.
