《Research on fault diagnosis method of piston rod based on harmonic wavelet and manifold learning》
After obtaining the relative change of the piston rod position Rxand Ryin the horizontal and vertical directions，the actual piston rod axis position（x，y）can be calculated.After obtaining the axial position（xi，yi，ti），i=1，2，…，n of the piston rod in a period of time t（for example，one cycle），the curve formed by these coordinate points is the axis orbit of the piston rod at this period.The characteristic parameter set of the axis motion as shown in Table 1 is presented to reflect the operating state of the piston rod[9].
