Create a flexible slider joint

The flexible slider joint requires a set of beam elements and the nodes that slide along it. If you want to add several beam elements or several nodes or other entities to represent the body that is displaced along the beam elements, you may want to create a group or selection recipe for the beam elements and for the body entities. The selection recipes and groups are easy to select when you create the flexible slider joint. For more information, see Selection recipes and Groups.

1. To create your own sensor node for the flexible slider joint, do the following:Note: If you let the solver create the sensor node for you, the solver generates the node label, and you must select all or none of the sensor nodes in the flexible slider output request. Make the FEM file the work part and the displayed part.Choose Nodes and Elements tab→Nodes group→Node Create .Click in the graphics window, drag the node to your preferred location, and complete the Node Create dialog box. To change the node display to make it more visible, in the Top Border bar, click Node Marker Drop-down.

2. Make the Simulation file the work part and the displayed part.

3. Choose Home tab→Loads and Conditions group→Flexible Slider simulation object.

4. Complete the Flexible Slider dialog box with the minimum required options, as follows: In the Nodes group, select the body using the graphics window, a selection recipe from the Simulation Navigator, or a group from the dialog box.In the Elements group, select the beam elements using the graphics window, a selection recipe from the Simulation Navigator, or a group from the dialog box. From the Slider Type list, select the joint type.In the Driver/Sensor group, select how you want to drive your flexible slider joint.If you drive the flexible slider, its curvilinear abscissa is computed automatically.If you don’t drive the flexible slider, select Sensor to request the computation of its curvilinear abscissa.None indicates that a load set or another part of your model will drive the movement of your assembly.For details on each option, see Flexible Slider dialog box.

5. If the flexible slider joint is not added to your solution yet, drag it from the Simulation Objects Container in the Simulation Navigator to the Simulation Objects container in the solution.

6. If you created sensor nodes for your flexible slider joint, or if the solver is generating the sensor nodes for you, request output for your flexible slider joint as follows:Right-click your solution and choose Edit.On the Case Control page, from the Output Requests list, select an output request and click Edit , or click Create Modeling Object to create a new one.In the Structural Output Requests dialog box, from the list of output requests, click Flexible Slider Result, and select the Enable FLXRESULTS Request check box.From the Entity list, select how you want to select the sensor nodes.For more information, see Structural, FRF, and Thermal Output Requests dialog boxes (Nastran).
