Opis:: In this study, abnormal vibrations of 1 pump fluid in a crude oil efflux station in the Changqing Oilfield was investigated. Kinetic simulation was applied to flow fields in the crude oil efflux pump using Ansys to determine trends of the impeller static pressure, speed, total pressure, wall pressure of the impeller, outlet pressure and pressure on the pump shell and to identify the reasons behind the abnormal vibrations. The results indicated that the axial vibration amplitude of the pump could be reduced from 1.3mm down to 0.68mm if the operation parameters of the external control oil pump were set as 2500-2550r/min and 325-335m3/h, respectively.

Opis:: For pursuing high performance, the development of semi-active suspension control tends to be complicated and ignores practicability. A new mixed control method effectively suppressing vibration of the vehicle body in the whole frequency band is proposed based on electromechanical analogy theory. Simulation results show that in comparison with passive suspension, on a long slope bumpy road, the mixed control reduces body acceleration by 21.49% and the maximum amplitude by 22.40%. On a C class road, the mixed control reduces body acceleration by 9.78%. Finally, an ECU hardware-in-the-loop test is conducted, which verifies the effectiveness and feasibility of the new mixed control method.
