THEORETICAL INVESTIGATION OF MULTIDIMENSIONAL FORCE/MOMENT MEASUREMENT DYNAMOMETER

The precision in the measurement of three-dimensional force/moment is very necessary for the manufacturing process, for satellite, and in military equipment. The purpose of this research is to design a multi-dimensional multi-point force/moment (F/M) measurement MP-M dynamometer model based on three-axis piezoelectric sensors installation. The FEM simulation is performed using ANSYS software and mathematical analyses are carried out using derived equations. The measured FEA results are consistent with the applied standard force/moments. The error difference of FEM analysis is under 1%. The FEM simulations results are approximately 99-100% of the exerted axial force, vertical force and pitch moment respectively. The designed MP-M dynamometer model is capable to measure spatial force/moment accurately and simulation experiments are discussed.
