摘要
两个相互垂直的简谐振动的合成,可以通过理论严格导出,也可以用示波器等仪器进行演示.对于非正弦波合成的情况,会比较复杂.该文利用Matlab软件很好地模拟了两个相互垂直的三角波型振动的合成,绘制出不同频率比、相位差的合成图像.从模拟的结果来看,其合成图象与正弦波的合成具有类似的规律.
The composition of two perpendicular harmonic vibrations could be done by theory derivation, or demonstrated through oscilloscope. But it would be complex about the situation of non - harmonic composition. In this paper, the composition of two perpendicular triangle wave vibrations have been simulated perfectly by Matlab software, and the composite images of different frequency ratios and phase differences were drawn. The result showed that the composite images had the similar rules with the harmonic vibrations.
