多信号分析方法的研究

Research on Analysis Methods of Multi-Signals

信号分析是测试过程中的重要技术,要从纷繁复杂的信号中挑选出所需要的信号,就必须有一套行之有效的科学方法。通过对递纸机构实验台相关信号的分析,总结出了一般多信号的处理方法,如峰值提取法、固有频率频次分析法、齿轮等随速度变化信号寻找法等。这些分析方法的应用显著简化了信号分析过程,并确保了信号分析的准确性。

Signal analysis is one of important techniques in measuring process, one set of scientific methods are necessary to pick up demanded signals from those complicated data. Through the analysis on those signals of paper-transferring mechanism, some general methods of managing multi-signals are obtained, such as peak values picking up method, analysis method for natural frequencies, searching method for gear signals with different speeds. These methods simplify the analyzing process of all signals, accuracy of signal analysis is guaranteed.
