摘要 |
FIELD: motion of various cargoes in air medium. ^ SUBSTANCE: proposed method consists in placing stepped regular piezo-ceramic surface on convex or taper surface coaxially relative to it for performing reciprocating oscillations by applying alternating stress orthogonally relative to common axis. Piezo-ceramic surface is made in form of single structure or in form of fragments located in succession. ^ EFFECT: enhanced reliability. ^ 2 dwg |
