智能材料结构的研究进展

Smart Material and Structure Research

智能材料结构是当前国内外研究的热门课题，进展很快。它的兴起将冲击材料研究部门，并引起了结构设计部门的变革。本文主要介绍埋入传感元件、驱动元件并采用人工神经网络、图形特征识别及新型声发射系统的三种强度自诊断智能结构，埋入形状记忆合金丝的大面积强度自适应结构，以及预报材料疲劳寿命、减振降噪、无舵面机翼和光电红外隐身等智能结构的研究进展。

Smart material and structure is the research focus both abroad and in our country and the development is rapid. The growth of the smart material and structure will impact on the research department of material and will cause change in the sturcture designing department. This article introdues the development of several kinds of smart materials and structures,including self-diagnostic and self-adaptive strength systems, materials fatigue life predicting systems, vibration and noise reduction systems, and no rudder plane wings and optoelectric stealth systems.
