英文摘要：

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.
