Coupled Clutches

Introduction

By coupling clutches together, a variable structure drivetrain can be achieved. With different clutches engaged at different times, torque is supplied to different parts of the system. In the accompanying notebook, the system is analyzed using built-in templates. These simplify many of the model analytics tasks that can be performed on SystemModeler models with the Wolfram Language.

In order to get the full experience of this example, you need the following:

• A desktop Wolfram Language product; a free trial download is available at www.wolfram.com/mathematica/trial/
• The CoupledClutches.nb notebook that came in the same bundle as this model

Simulation

Simulating the model allows you to look at how the different inertia components behave over time, and how they are affected by each other. In order to properly analyze this model, it is recommended to use the Wolfram Language notebook that came with this model when it was downloaded.

To simulate the model in SystemModeler, do the following:

• Click the Simulate button .

When the simulation is finished and Simulation Center has been opened, you can analyze the result by clicking the various states or Stored Plots to the left of the Simulation Center window. For example, AngularVelocities shows the angular velocities of the inertia components over time, while Clutch1EngagementVelocities shows the relative velocities of the first and the second inertia components, as well as the force applied to the clutch between them.

To analyze the model based on a different parameter set than the default, select the state you want to edit in the Model Center and change the desired initial value under Parameters in the General tab. It can also be done directly from Simulation Center, under the Parameters tab. Changing the d parameter will change the damping on the first and the last inertia components, for example.
