摘要：
In this paper, a double hinge-beam with a variable quadratic flexure moment is described. This smart beam can undergo a significant change of deflection. A shape memory alloy is used to obtain the moment of the change of flexure. Structure shape can be changed because of elastic energy stored in the beam by prestrain can be modified. The actuator is used to change the stress distribution of the beam. This concept is more efficient than a classical method, where all the energy is provided directly by the actuator. A thermomechanical model of the beam is proposed, and experimental data demonstrates its accuracy.
