Logic-Controlled Clutch
Friction controlled clutch.
Description
The Logic-Controlled Clutch unit is a logically controlled mechanism that transmits torque by friction. This unit is an advanced version of the Fundamental Friction Clutch unit. You control the Logic-Controlled Clutch using a signal on the E port.
If the clutch is engaged and there is slip between the clutch parts, the unit transmits the slip friction torque. If the clutch is engaged and there is no slip, the torque on the driven shaft is equal to the torque on the driven shaft.
Parameters
Main
Transition model - parameterization of clutch engagement
Instantaneous (by default) | First-order lag | Scaled by input
Parameterization of clutch engagement:
-
Instantaneous- the clutch is enabled when the input signal on port E is rounded to 1, and the clutch is not enabled when the input signal is rounded to 0. -
First-order lag- the block introduces a first-order delay for clutch engagement according to the value you specify for the Transition time constant parameter. -
Scaled by input- the block smooths the input signal on the E port. The block applies full static and kinetic friction when the input signal is greater than or equal to 1, and does not apply static or kinetic friction torque when the signal is negative. The block linearly scales the friction moments when the input signal is between 0 and 1.
Kinetic friction torque is the boundary sliding friction torque
10 N*m (by default) | `non-negative scalar'.
Minimum torque value to maintain relative motion between the clutch discs.
Static friction torque - static friction boundary torque
20 N*m (by default) | positive scalar
Minimum torque value that causes relative movement between the clutch discs.
Clutch velocity tolerance - sliding velocity limit value
0.001 rad/s (by default) | Non-negative scalar
Minimum clutch angular velocity.
Initial State - initial state of the clutch
Unlocked (by default) | Locked.
Option to start simulation from unlocked or locked state.
