摘要：由于工程机械油压信号易受各种噪声的影响，难以提取有用的信号特征。该文对比了数学形态学降噪、小波阈值降噪、EMD自适应降噪、改进EEMD自适应降噪四种方法，通过仿真信号和实测信号对四种降噪方法进行检验，结果表明：对于一般的信号，小波降噪、EMD降噪、改进EEMD降噪、数学形态学降噪都可以进行降噪处理，并提取趋势项。但是对于含有冲击或突变信号的油压信号，基于数学形态滤波器的方法最好，所得到的信号不失真、信噪比最高。

Abstract: Due to engineering machinery hydraulic signal is vulnerable to the effects of all kinds of noise, it is difficult to extract useful signal characteristics. This article compares the mathematical morphology noise, wavelet threshold de-noising, the EMD adaptive noise reduction, EEMD four adaptive noise reduction method, and through the simulation signal and the measured signal to the test in the four types of noise reduction method, the results show that for the average signal, wavelet de-noising, the EMD de-noising, EEMD de-noising, mathematical morphology noise reduction can be noise reduction processing, and extract the trend. But for oil pressure signal contains or abrupt signal, the method based on mathematical morphology filter is best, the resulting signal distortion, the highest SNR.

Abstract: A pump-controlled cylinder system is introduced. The pump-controlled cylinder system uses a low-pressure accumulator as an auxiliary fuel tank. The working principle of AC servo pump-controlled hydraulic system is briefly described. Based on the AMESim software, a simulation model of the hydraulic system was established, and the effects of the accumulator inflation pressure and the charge valve opening pressure on the performance of the hydraulic system were studied. The relationship between the accumulator inflation pressure, the check valve opening pressure and the hydraulic oil pump drain pressure is analyzed. It is determined that the system performance is good when the accumulator pressure is 3 bar and the charge valve opening pressure is 2 bar. which provides guidance for the engineering practice of this type of hydraulic system and provides a theoretical basis for further optimization.

Abstract:  During the commissioning of a plug-out device, the abnormal increase of pressure in the positive chamber of the radial cylinder occurred. In this paper, the causes of the failure are analyzed, and the possible fault points are checked. Finally, the fault point is located as a certain type of electro-hydraulic reversing valve. The reason for the failure is that the asymmetric structure of the valve core leads to excessive oil return resistance. For the fault point, AMESim is used to simulate the fault injection, which verifies the accuracy of fault analysis and proposes solutions. The test results show that the fault location is accurate and the solutions are effective.

Normally, it works at constant pressure Stability is determined by the pump outlet pressure, valve spring, valve cover amount, variable piston and other components, and the parameters are correlated and affect each other. The influence of variable piston clearance on the constant pressure control stability of hydraulic pump is studied through AMESim simulation and practical test. The results show that different piston clearance will affect the constant pressure working stability of hydraulic pump.
