Actuating Effects of Embedded Shape Memory Alloy on Fiber Reinforced Polymer Beam

着重研究了形状记忆合金偏心埋置于树脂复合材料梁/板后,合金在逆相变过程中对梁弯曲变形的驱动效应。试验结果表明:合金在逆相变过程中能对树脂基复合材料梁产生很大的驱动力,可以按需要主动控制复合材料梁、柱的变形;合金的预应变值因素对于合金的驱动效应有较大影响,合金可以进行多次激励。

This paper studied the actuating effects of the shape memory alloy wires eccentrically embedded in the beam on the deformation of fiber reinforced polymer beam during phase transformation. It is found that the initial pre-strain, the cross section of the specimen have significant influence on the test results, large recovery force can be obtained while actuating the wires, the shape memory alloy actustor is successfully utilized as a way to control the deflection of ploy beam , the shape memory alloy wires could be actuated again.
