MATLAB: How to parameterize hydraulic valve with given manufacturer data sheet current vs flow rate

MATLABSimscapesimulink

Dear All How do i parameterize the 2 way and 3 way directional valve with given manufacturer data sheet current vs flow rate?

Best Answer

The directional valve blocks have a Model Parameterization option in their dialogs. Two of those values let you enter your own data from, e.g., a datasheet.

From the documentation:

By area vs. opening table — Provide tabulated data of valve openings and corresponding valve passage areas. The passage area is determined by one-dimensional table lookup. You have a choice of two interpolation methods and two extrapolation methods.
By pressure-flow characteristic — Provide tabulated data of valve openings, pressure differentials, and corresponding flow rates. The flow rate is determined by two-dimensional table lookup. You have a choice of two interpolation methods and two extrapolation methods.

The Laminar pressure ratio is the ratio between the downstream pressure and the upstream pressure. When this ratio is reached, it will transition to a laminar regime.

MATLAB: How to model flow rate caused by a decreasing volume as in a piston with SimHydraulics 1.1 (R2006b)

There are three flow rate components associated with the moving piston:

    - flow rate caused by the piston motion,             q = A * v,
    - flow rate caused by the fluid compressibility,   q = V/E * dp/dt
    - flow rate due to leakage, if any                         q = K_l * p.

The flow rate associated with the piston velocity is accounted in the hydro-mechanical converter while the compressibility-caused flow is accounted in the variable volume chamber block. It gives you the possibility to build cylinder models with various level of idealization of a very limited set of building blocks.
