PLANAR ACTUATOR WITH SANDWICH STRUCTURE AND APPLICATION TO TORSION OF A STRUCTURE

摘要

The actuator has a sandwich structure symmetric with respect to a median plane intended to provide a plane strain by shearing. A piezoelectric planar layer (1) has an active direction superposed and integrated to fabric layers (2, 3) which have rigid frames and chains oriented along two directions to form an interconnection. The active direction is oriented along a diagonal of the interconnection. Adhesive joints (4, 5) are disposed between the three layers.
