excitation. In order to demonstrate the effectiveness of proposed model, the simulation results are validated with experimental ones. Finally, to achieve the optimal valve geometry, numerical results for various shapes of valves are compared. Rounded valve with the least amount of flow turbulence obtains lower fluctuations and vibration amplitude compared with the flat and steep valves. Simulation......

The equivalent beam width is affected by many factors......
, cone-type throttle valve experiments are carried out to study the thermodynamic processes of cavitation. First, the processes of growth and collapse are analysed, and the relationships between... system are summarised. Using the cone-type throttle valve as an example, a method to suppress cavitation is proposed. Key words: cavitation; bubble collapse; hydraulic oil temperature; Rayleigh......
is developed, taking the coupling between torsional and lateral vibrations into account. It is assumed that a shaft is regarded as a continuous viscoelastic shaft with unbalanced and small deformation properties. The equations of motion for the torsional and lateral vibrations are derived using Lagrange’s approach with the frequency-dependent shape function. The rotor torsional vibration......
