Theoretical analysis of operation of power actuator with shape memory alloy rod working body and elastic bias body

Abstract

The operation of a multiple-acting linear power actuator with a shape memory alloy rod working body and a bias elastic body is described. The conditions for the implementation of a closed two-way shape memory effect in such a system have been formulated, analytical expressions for the maximum values of the working stroke, payload and useful work of the power actuator have been obtained.
