摘要
研究开发计算机辅助材料振动和分析系统的数据采集、数据传送及频谱分析。采用电路与８０９８单片机连接采集信号，然后将数据传送到计算机。频谱分析采用原址运算。结果表明，采用上述方法解决了系统数据采集和信号传输的不稳定现象，以及运算中占用内存大、时间长的问题。
The data collection,delivering,and frequency analysis in computer aid determination and analysis system for vibration of materials are studied in the present research.The results show that the methods eliminated the instable phenomenon in data collection and delivering,and the problems that big memory space and long time are taken during calculation.
