APPlicationofWaveletAnalysisinFaultDiagnosisofRota
本文阐述了研究背景,故障诊断技术的发展及其国内外发展现状。对旋转机械的常见故障及其机理做了介绍,从而明确了旋转机械故障诊断所需要的依据及诊断方法。整个系统进行了总体的设计,并对各个模块做了简要的介绍,比较了传统的故障诊断方法和小波分析方法,分析了在旋转机械故障诊断中引入小波分析的必要性。最后两章分别详细地介绍了系统中的两个核心模块的设计与实现。实践表明,该方法提高了故障诊断的准确性,取得了良好效果。同时,小波分析的结果还可以为以后的专家系统,智能诊断提供数据。(There15agreatdealofnon一stationarysingalsinmachineryoPeration.Buttraditional

基于无迹卡尔曼滤波的人工神经网络matlab程序(Similar to using the extended Kalman filter, Neural Networks can also be trained through parameter estimation using the unscented Kalman filter.
This file provides a function for this purpose.
It also includes an example to show how to use this function.)

在虚拟仿真环境下进行了几种不同规格零件的抓取试验。在ADAMS中进行仿真试验设置,创建传感器及仿真脚本命令,对两种规格零件进行了抓取试验分析,进一步验证结构设计的正确性及合理性。(the capture of several parts with different specification test was carried out in a virtual simulation environment. To further verify the correctness and the reasonable of the structural design, in ADAMS simulation test, the crawled test and analysis was done for two specifications of parts with the creating of command script and sensor.)
