ABSTRACT:
A multi-component dynamometer for measuring forces and torques includes two force introduction plates and pre-oriented transducer elements without housing arranged between them. Each transucer element comprises typically a rectangular plate and two pre-oriented piezoelectric elements fixed thereon, one of these being sensitive to shear in a direction parallel to one edge of the carrier plate and the other being sensitive to pressure in a direction parallel to the normal of the carrier plate. The pre-oriented transducer elements enable the number of piezoelectric elements and electrical connections to be reduced substantially when assembling measuring platforms, as well as the amount of orientation and testing work. The platforms can be made flatter and more rigid, thereby raising the natural frequency. The electronic measuring and evaluation parts can be integrated partially or wholly into the dynamometer.
