Reduction of a homogeneous ellipsoidal material volume to a discrete system of material points In reference [4], two elementary third-order bodies were analyzed: tetrahedron and oblique prism with parallelogram bases.
a) b) Fig. 1 Homogenous ellipsoidal material volume and the equivalent system of seven material points An analogous property is valid for an ellipsoidal rigid material volume (Fig. 1 a).

TRUSM utilizes the vibration of the elastic body (stator) in the ultrasonic frequency band and the reverse piezoelectric effect of piezoelectric materials.
Models above did not take into account the radial slide between the stator and the rotor and the transformation efficiency of the piezoelectric materials.
