摘要：In hydraulic pump system various states can occur caused by mechanical and physical phenomena. To detect them,the Short Time Fourier Transform (STFT) is applied. This paper will consider an application of STFT to monitorand evaluate hydraulic pump system operation in different states of operation. For measurements of pressure andflow changes in pump, hydraulic tester and Data AcQuisition (DAQ) card was used for evaluation of qualitativeand quantitative changes in the system. Results of hydraulic pump’s operation will be shown on Fast FourierTransform (FFT) charts and STFT spectrograms plots.
