Determining the Effect of Flow Variations to Vibration Tendency in a Hydraulic Manifold

A hydraulic manifold is an important component in hydraulic machinery that transports high-pressure hydraulic oil into hydraulic tubes and hoses for cleaning. Because of the high pressure used during operation, this process causes vibration and the possibility of leakage at the hydraulic manifold’s exit ports. The purpose of this research is to determine the effects of pressure and velocity variations in a hydraulic manifold on vibration tendency. Computational fluid dynamics (CFD) is used in this study to simulate the hydraulic manifold fluid behaviors. under the operating conditions of the industry The results show that pressure and velocity fluctuations occur at each branch of a mainstream due to changes in area and geometrical shape. At each branch, there was a surge of pressure but a decrease in velocity. Overall, the results show that the areas closest to the inlet are the most affected. The increments have little effect on areas further downstream. According to our calculations, the vibration tendency occurs in the hydraulic manifold cavity due to differential pressure and velocity, negative pressure, low velocity, swirl flow, and back stream.
