_风力发电机组叶片故障诊断
风机叶片的裂纹和断裂是导致风机机组事故的重要因素之一，尽早诊断出风机叶片的
故障部位与故障程度，对安全生产具有意义重大。本文将叶片振动信号作为研究对象，利用小波分解方法对其进行信号分解，并与时域和频域方法处理结果进行对比分析，得出诊断结论。仿真结果表明: 小波分解方法可以更有效的获取故障特征信号，具有较高的故障诊断率。(The crack and fracture of fan blade is one of the important factors that cause the accident of fan set. It is important for safety production to diagnose the fault location and failure degree of fan blade as soon as possible. In this paper, the vibration signal of the blade is taken as the object of study. The signal is decomposed by the wavelet decomposition method, and the results are compared with the time domain and frequency domain methods. The diagnosis conclusion is obtained. The simulation results show that the wavelet decomposition method can acquire the fault characteristic signal more effectively, and has higher fault diagnosis rate.)

灰色粒子群算法在结构损伤识别中的应用
说明： 首先介绍结构模态在结构损伤识别中的应用，对模态置信度和柔度置信
度进行了相关性研究。其次讲述了单目标函数粒子群优化算法的基本流程，通过
一简支 T 梁，以基于模态置信度和柔度置信度的两种单目标函数进行结构的损伤
识别。通过对比，发现两种单目标函数的优缺点。紧接着将上述两种指标同时利
用，构建相关的目标函数。利用灰色理论中的关联度，将两目标函数粒子群优化
算法转化为单目标函数粒子算法，进行结构的损伤识别。结果表明相对于与单目
标函数，前者识别效果更好，更能精确进行结构的损伤识别。最后以实验室组合 T
梁为研究对象，在不同损伤工况条件下，将灰色粒子群算法应用其中，进行梁的
损伤识别，发现识别区域与裂纹的分布情况大致相符。(Particle swarm optimization)
