在测量机械振动,包括水力机械的水压脉动时,所记录的振动波形曲线常常是由多个简谐振动波形曲线组合而成。为了避免共振或寻找引起共振的原因,以便采取防振措施,这就需要对已测得的振动曲线进行谐和分析。下面介绍两种计算方法的实例,供分 When measuring mechanical vibrations, including hydraulic pulsations of hydraulic machines, the recorded vibration waveform is often a combination of multiple harmonic vibration waveform curves. In order to avoid resonance or to find the cause of resonance in order to take anti-vibration measures, which need to be measured on the vibration curve harmonic analysis. Here are two examples of calculation methods for points
