摘要: 提出了嵌入形状记忆合金丝和压电陶瓷片作为联合变形驱动器的二元智能结构,并建立了有限元模型.驱动器镶嵌于层板表面或内部,其中压电陶瓷片作为压电铺层;形状记忆合金丝的驱动力当量为与温度相关的节点载荷.算例比较了不同种驱动方式的变形效果,并进行了试验验证.结果表明在二元智能结构的形状控制中,形状记忆合金丝承受主要的载荷,压电陶瓷片作变形修正,可以发挥各自的优点.

Abstract: A hybrid smart structure integrated with shape memory alloy slims and piezoelectric ceramic patches as united actuators, was presented and modeled by finite element methods. Being bonded to its surface or embedded in the laminate, the piezoelectric ceramic patches was treated as a certain layer while the shape memory alloy slims as the load subject to the temperature. The comparison among the effects of different control methods was given, and validated with static experiment. The result indicate that the shape control of the hybrid smart structure can take advantage of their characteristic with shape memory alloy actuators holding the mostly load and piezoelectric ceramic actuators correcting the precise shape.
