Pressure Control Solenoid

This example shows how to model, parameterize, and test a pressure control solenoid valve. This example also generates a plot of the relationship between applied solenoid force and the resulting actuator port pressure.

Model

The following figure shows the model of a pressure control solenoid valve. Here P represents the pressure source port,T represents the reservoir, and A represents the actuator port.

Pressure Control Solenoid Subsystem

This subsystem shows how the pressure control solenoid valve is modelled.

Mass Dynamics Subsystem

This subsystem shows how the spool mass dynamics are modelled, including the forces on the spool due to spool inertia; the forces on the spool due to the spring, damper, and hard stop; friction between the spool and the valve body; the change in fluid momentum at the valve entry and exit; and the pressure acting on the spool surface.

Pressure Force Subsystem

This subsystem shows how the fluid pressure at port A is modelled as a force on the spool left face.

Orifice AT Subsystem

This subsystem shows how the orifice between ports A and T is modelled.

Orifice PA Subsystem

This subsystem shows how the orifice between ports A and P is modelled.
