Studying different design variants

COUPLE is a great ally when you want to examine different design variants. In fact, you can easily create the topologies of your different variants and compute the results all at once to compare them. For example, you can compare different e-motors by just duplicating the variant and replacing the engine model. You can also study different mounting conditions by adding stiffness to the links between components.

To study different design variants, you have to complete the following steps:

  • Setting up the library.
  • Modeling the variants.
  • Computing the coupling.
  • Analyzing the results.

Setting up the library

The first step consists in setting up all the needed models in the library. This consists of:

  • Creating a library.
  • Adding models to the library and setting interfaces.

Creating a library

To create a new library from scratch, complete the next steps:

  1. Click .
  2. Browse the correct location.
  3. Type the desired library name.
  4. Click Save.

Adding models to the library and setting interfaces

To add a model to a library and set the interfaces, complete the next steps:

  1. In the library in the design area, click .
  2. Browse the directory of the model.
  3. Drag and drop the model to the right side.
  4. Fill in the desired information.
  5. Select the library where you want to import the model (at the bottom of the window).
  6. Click Channels & Interfaces.
  7. Set up the interfaces correctly.
  8. Click Import.

Modeling the first variant

To create the assembly topology, complete the next steps:

  1. Open the fly-in library.
  2. Drag and drop the components or loads to the design area.
  3. Click the link tool .
  4. Connect the corresponding interfaces.
  5. If desired, drag and drop a stiffness model to the link.

You can rename the variant by right-clicking on the top tab and selecting Rename.

Modeling the next variants

After designing the first variant, you can create new ones in different tabs.

To create a new variant, complete the next steps:

  1. Add a variant tab by clicking on .
  2. Add models and links.

If your following variant has minor differences from the previously designed one, you can duplicate the existing variant by right-clicking on its tab and selecting Duplicate.

Computing the coupling

To compute the coupling, complete the next steps:

  1. Click .

Analyzing the results

To analyze the results, complete the next steps:

  1. Click .
  2. If needed, activate the Graphs and Data Overview modules.
  3. Right-click on the dataset.
  4. Select Plot and the desired data type.

You can also plot one or multiple datasets by dragging and dropping them in the Graphs area.
