The diagrams of damping valve with annular slice and hydro-pneumatic spring are given. According to the calculation method of the sectional linear speed characteristic, the damping coefficients and the resistance values at the valve open point and the maximal valve open point are deduced. Based on the principles of sheet deformation and aperture throttle, the function relation between flow and pressure...
With regard to the situation that there isn't a turbulence flow equation of eccentric annular aperture, an aperture throttle analysis calculation method based on turbulent state is provided. At first, the three-layer speed distribution formula of fluid in turbulent state is given by using boundary layer theory. When the aperture is lager than the eccentricity, the phenomenon that the transition layer...
