摘要
通过实验确定TiNiFe形状记忆合金的材料参数,建立该合金的本构方程。对升温恢复过程中管接头和被连接管系统的应力场进行模拟计算,研究管接头内径、壁厚和装配间隙等参数对径向压应力的影响。计算结果表明,为了提高连接强度,可以适当增大管接头壁厚,减小管接头内径和装配间隙。
The material parameters of TiNiFe shape memory alloy were determined by experiments, and the constitutive model was established. The coupling force of the system of pipe-coupling and connected tube was simulated with raising temperature, and the influences of inner diameter, wall thickness and fit clearance of pipe-couplings were investigated. In order to improve the connecting strength, the wall thickness was properly increased, and the inner diameter and fit clearance should be decreased.
