摘　　要：研究了共享参数模型的软件体系结构,设计了非平稳信号分析系统的总体框架,实现了系统模块的统一构架和仪器界面,采用面向对象的编程技术以及VC开发工具,成功开发了面向机械故障特征提取的非平稳信号分析系统,为故障特征提取提供了一个有效的分析工具,并通过实际应用验证了该系统的实用性。This paper introduced a system structure of the parameter-sharing module software, put forward the blueprint of designing and the model of developing component-based non-stationary signal analysis system, implemented the uniform framework of the system module and the apparatus interface successfully. Based on the non-stationary signal analysis methods, combined with object oriented programmable technology and the VC development tools, developed the non-stationary signal analysis system for mechanical fault feature extraction successfully. It has provided a new method for signal test and analysis, and proved to be practical and availability by some project applications.
