Abstract
The main component of any force measuring transducer is its elastic element (EE). It is compulsory to produce EE in one piece only, from a good quality and easy to work on material. The monolithic elastic structure ensures the stable and linear relationship between loads and deformations. When EEs are complex, analytical computation is not possible and/or design nomograms do not exist, experimental methods of investigation (photoelasticity, holography, Moiré analysis) may be used; however, in most cases numerical computation is unavoidable. CAD (computer aided design), combined with FEA (finite elements analysis), facilitates their modeling and parametric optimization. Relevant examples are presented, together with useful information concerning fabrication, testing, calibration and databases for force transducers.
