Study on Mechanical Properties of Shape Memory Alloys and Their Application in Variant Structures
形状记忆合金(Shape Memory Alloys,SMA)由于其特有的形状记忆效应(Shape Memory Effect,SME)被大量研究和广泛应用.基于SMA的Müller-Achenbach-Seelecke模型进行了单根SMA丝的回复力数值计算验证,并设计了一种SMA丝驱动器应用于机翼变后掠角结构中,完成了机翼连续后掠偏转的原理、方案和具体的结构设计,并加工制备了后掠机翼模型;同时为了实现机翼后掠角变化的精确控制,采用PID控制方法…查看全部>>
Shape memory alloys(SMA)have been extensively studied and applied because of their unique shape memory effect(SME).Based on the the Müller-Achenbach-Seelecke model of SMA,the return force of a single SMA wire is verified by numerical calculation,and a SMA wire actuator is designed and applied to the wing with integrated variable sweep angle structure.The principle,scheme and specific structure design of the wing continuous sweep deflection are implemented,an…查看全部>>
