[. . . ] In the Position row, select s[a](t) from the drop-down menu and, in the Force row, select F[a](t) from the drop-down menu. The right port is now defined as a translational flange and associated with the position variable s[a](t) and force variable F[a](t). Select the port at the top of the diagram. From the Port Type drop-down menu, select Signal Input. In the Value row, select c(t) from the drop-down menu. This port is now defined as a signal input and associated with the stiffness variable c(t). Select the port at the bottom of the diagram. From the Port Type drop-down menu, select Signal Input. In the Value row, select d(t) from the drop-down menu. This port is now defined as a signal input and associated with the damping variable d(t). Drag the port that you defined in step 14 and place it at the top right of the diagram. You can also drag the other port to position it. The ports will be displayed in this arrangement when you generate the custom component in MapleSim. 3. 4 Working with Custom Components in MapleSim · 53 Generating the Custom Component To generate the custom component, click the Generate MapleSim Component button at the bottom of the template. When it is generated, the custom component is displayed in the Library Models palette located in the Project tab in MapleSim. You can now add the NonLinearSpringDamper custom component to a model by dragging it into the model workspace. 3. 4 Working with Custom Components in MapleSim In MapleSim, you can work with a custom component in the same ways as you would work with a subsystem. You can perform the following tasks: Add Text and Illustrations to a Custom Component To customize the appearance of a custom component, you can change the default images that are displayed in the component icon. Select the custom component in the model workspace, click in the navigation toolbar, and use the drawing and annotation tools to add text and illustrations. Save a Custom Component as Part of the Current Model To save a custom component as a part of the current model, add the component by dragging it into the model workspace and then save the model. The next time you open the file, the custom component will be displayed in the model workspace and Library Models palette. Add a Custom Component to a Custom Library If you want to use a custom component in a file other than the current model, add the component to a custom library. For more information, see Creating and Managing Custom Libraries (page 35). 54 · 3 Creating Custom Modeling Components 3. 5 Editing a Custom Component If you want to edit a custom component that you have generated, make your changes in the corresponding Maple worksheet and regenerate the component. In the MapleSim model workspace, double-click the custom component that you want to edit. The corresponding Custom Component Template is opened in Maple. In the Maple worksheet, edit the equations, properties, or port values. [. . . ] In the Inspector tab, change the subsystem name to ConnectingRod and change the length value to 2. 104 · 6 MapleSim Tutorials Adding the Fixed Frame, Sliding Mass, and Joint Elements In this task, you will add a Fixed Frame component, a Rigid Body component to represent the sliding mass, and the joint elements. From the Multibody Bodies and Frames menu, add the Fixed Frame component and place it to the left of the Crank subsystem. From the same menu, add a Rigid Body component and place it slightly below and to the right of the Connecting Rod subsystem. Add the following joints: · From the Multibody Joints and Motions menu, add a Revolute joint between the Fixed Frame component and the crank, a second Revolute joint between the crank and the connecting rod, and a third Revolute joint between the connection rod and the sliding mass.
