摘要
采用虚拟仪器技术,重点介绍了两种关于信号分析的虚拟仪器:联合时频分析和小波分析虚拟仪器,应用于航空发动机转子实验室的信号测试与分析系统。为振动信号的分析和航空发动机故障诊断中提供分析手段。
By means of virtual instrument technology,this paper focuses on two virtual in stru-ments for signal processing on aeronautical engine fault diagnosis:joint time -frequency analy-sis and wavelet analysis virtual instru ment ,which are available in analysis of vibration sig nal and fault diagnosis of aeronautical engine.
