I’m trying to model a vertically mounted piston system in Simscape where the piston supports a variable weight (parameter-controlled). The system consists of a gas-sprung hydraulic actuator that uses a floating piston to separate the gas volume from the hydraulic oil volume. The purpose is to maintain a pressure-balanced condition to support the load while allowing controlled height adjustment.
Key features of the system:
The piston is mounted vertically to the ground.
The upper chamber contains compressible gas (e.g., nitrogen), acting as a spring.
The lower chamber contains hydraulic oil.
A floating piston separates the gas and oil, maintaining pressure equilibrium.
The supported load is a variable parameter.
The system includes height (position) control of the main piston.
I need guidance on:
How best to model the gas/oil separation with a floating piston in Simscape.
Incorporating the gas spring behavior.
Implementing height control in the model.
Handling the variable load and its interaction with the system.
Any help, component suggestions, or example models would be greatly appreciated.I’m trying to model a vertically mounted piston system in Simscape where the piston supports a variable weight (parameter-controlled).
