摘　　要：可以用不同编程语言来实现振动测试信号处理和分析系统,但这些语言在分析功能和图形处理的编程方面难度较大;由于MATLAB具有强大的信号处理与分析专用函数库以及丰富的图形显示能力,在此平台上进行M文件的编程直接调用这些功能来设计该系统比上述语言具有独特优越性、容易实现,并可运用MAT-LAB的图形界面(GUI)功能建立在WINDOWS系统下可执行的系统操作界面。本文介绍了设计的系统结构框图、用GUI功能建立图形界面的过程和实现部分功能的编程语言,用实例演示和证实了有关功能处理的结果。Different progamming languges can be used to realize a vibration test signal processing and analysis system. But it is difficult for these languages to program in the cases of signal analysis functions and graphics processing. Because MATLAB has many powerful signal processing, analysis functions and much graphics processing ability. Based on MATLAB, it is more superior and easier to realize this system by M file programs using directly these functions than by the above languages. Furthermore the MATLAB GUI function is used to realize the operation interface of the system based on WINDOWS. This paper also introduces the strutrural frame of the system, partial programming languages of the system and process for graphics interface built by GUI function. Some functions of the sytstem are demonstrated and validated by examples.
