MATLAB: Simulation of a missile valve with Simscape

MATLABSimscapesimulinkvalve

Hello,

I would like to realize a missile valve in Simscape. For the valve I use the Local Restriction. Now I would like to close the valve when a previously defined mass or volume flow is reached and keep it closed until the end of the simulation.

A first approach was to implement an if-condition in Simulink. I was able to use this to close the valve when a defined mass flow was reached but not able to keep it closed, as it reopens as the mass flow drops.

Does anyone have an idea how I can keep the valve closed state? Is there a corresponding block in Simulink or Simscape?

Thanks a lot and greetings

Tom

Hi Tom,

A flip-flop will latch the valve shut once the flow reaches the threshold and keep it shut until you manually reset it. That is an S-R Flip-Flop in the picture.

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.

MATLAB: Cross-Sectional Area at Ports in Simscape

In general, "Cross-sectional area of port A/B" represents the area of the connection to that block. The cross-sectional area at ports A and B of the flow resistance block usually have small impact on the flow rate through the block. The parameter exists because we need to determine the direction of flow and provide a smoothing for the temperature at a connection node when the flow direction changes (i.e. flow reversal). The threshold for smoothing the nodal temperature based on a Mach number, so the cross-sectional area at the port is used to divide the mass flow rate to get the velocity and Mach number.
