Help Text for single acting actuator block
This block is the model of a single acting linear actuator.
The inputs to the block are:
- the controlled flows from the valve [m3/s]
- the external force acting on the actuator (a constant) [N]
- the force transmitted by the a second mass connected to
the actuator output through a link, having a defined
stiffness [N].
- the uncontrolled pressure acting on the second actuator
chamber; it can be the supply pressureor the return
pressure (the first and the second element of the output
from the Accumulator block) or the atmospheric pressure (a
constant)
The input 3 shall be connect to the output of a 'Stiffness
& Mass' block or to a 'Ground' block if the second mass is
not present..
The outputs are:
- the actuator position [m]
- the actuator speed [m/s]
- the pressures into the controlled actuator chamber [Pa]
