Squeal noise in hydraulic poppet valves [PDF]
Journal of Zhejiang University: Science A, 2016 The poppet valve is a fundamental component in fluid power systems. Under particular conditions, annoying “squeal” noises may be generated in hydraulic poppet valves. In the present study, the frequency spectrum of the squeal noise is obtained by analyzing the sampling data from the accelerometer mounted on the valve body.
