The article discusses modern methods of diagnosing and technical diagnostics irrigation pumping units to ensure reliability during operation. Using new designs power equipment developing operating modes provide for improving the mode pumps based on improved diagnostics, significantly saving costs. Together with this provides detection, control, prediction multi-stage failure rolling bearing by ...

To fully utilize the fault information and improve diagnosis accuracy of rolling bearings, a multisensor feature fusion method is proposed. The contains two steps. First, intrinsic mode function (IMF) each sensor vibration signal calculated by variational decomposition (VMD), redundant such as noise eliminated. Then, time-domain, frequency-domain multiscale entropy features are extracted based ...

Abstract Rolling bearing is an indispensable part of the contemporary industrial system, and its working conditions affect state entire system. Therefore, there great engineering value to researching improving fault diagnosis technology rolling bearings. However, with involvement whole mechanical equipment, we need have a large quantity data support accuracy diagnosis, while efficiency classica...

Abstract: Thin-walled integrated flexible support structures are the major trend in the development of current rolling bearing technology. A thin-walled, integrated, squirrel-cage flexible support roller bearing, quasi-dynamic iterative finite element analysis (FEA) model is established in this paper. The FEA model is used to calculate the structural deformation of the thin-wall rings and suppo...
