根据复合工艺的特殊要求，提出了特性能优异的NiTi形状记忆合金薄带经特殊处理以后，将其复合于易产生裂纹（或损伤）的构件内，与微机监控系统相配合，利用NiTi合金带的特殊性能，实现对构件内裂纹的自动探测和控制。作者对Ni－Ti合金带主要特征参量进行了测试。以铝合金-NiTi合金带复合智能构件为研究对象，针对其结构特点，建立一新的应力分析方法—拟温度载荷法对控制裂纹扩展的效果进行计算分析。通过所建立的微机监控系统，对NiTi合金带智能复合构件进行了主动探测和控制裂纹扩展的疲劳试验。
According to the special requirements of the composite process, the NiTi shape memory alloy ribbon with excellent properties is proposed to be compounded into the crack-prone (or damaged) component after special treatment. The NiTi shape memory alloy ribbon is matched with the computer monitoring system. Of the special performance, to achieve automatic detection and control of cracks within the component. The authors tested the main characteristic parameters of Ni-Ti alloy strip. Taking aluminum alloy-NiTi alloy ribbon composite intelligent component as the research object, a new stress analysis method-quasi-temperature load method is proposed to calculate and analyze the effect of crack growth control. Through the established computer monitoring system, NiTi alloy with intelligent composite components to actively detect and control fatigue crack growth test.
