Outline of Final Research Achievements

In order to improve dynamic correction method for a force sensor, we develop high-precision evaluating system of dynamic property of force sensors and evaluated and analyses the dynamic property. The measurement range and accuracy of evaluating system were improved. Some types of force sensors were evaluated and were investigated their dynamic properties by experimental results and FEM analysis. In addition to inertial, viscosity and delay of measurement equipment seemed to affect the dynamic error. We develop the correction method for the dynamic error and develop a software to correct the dynamic error with the correction method. We showed a way to resolve the problem that there is no evaluation method nor correction method for force transducers in the present state.
