Femap轴承载荷_BearingLoad

Introduction

In this exercise, you will create and compare the results of a load applied to the edge of a hole using two different types of load distributions. In this exercise, you will complete the following steps:

∙Open an existing model file

∙Create a Cylindrical Coordinate System for the hole on the plate

∙Apply a 100 lb. load on a curve

∙Using a Data Surface apply a 100 lb. bearing load on a curve in a separate load set

∙Expand the bearing load and set the load vectors to scale by magnitude

∙Set up and run a Multi-Set analysis

∙View and compare the results from the two analyses

Step 1:Open an existing model file

In this step you will open an existing model file and save it in your Exercises folder.

Start Femap.

∙Select the File, Import, Femap Neutral command.

∙In the Read Model from Femap Neutral dialog box, select the file, ex7-Bearing Load - inches.NEU from

your class files Geometry folder.

∙Click the Open button.

∙Your model should appear as follows:

Save the file in your exercises folder.

∙With the File, Save As command, save the model as ex5-bearing.mod in your training class exercises

folder.

Step 2:Create a cylindrical coordinate system for the large hole on the plate.

Create a coordinate system for the large hole.

Zoom in around the large hole on the right side of the plate.

∙Click the Zoom icon on the View toolbar.

∙Click and drag your mouse so that the right side of the plate will be displayed in your graphics window.

Create a new cylindrical coordinate system.

∙In the Model Info pane, right-click the Coordinate Systems object and select New from the context-

sensitive menu.

∙In the Define Coordinate System dialog box, enter: ID = 101

Title = Hole

Method to XY Locate

Type to Cylindrical

Click OK to continue with creating the new

coordinate system.

∙In the Locate – Define Coordinate System Origin dialog box, click the Methods button and select

Center from the menu.

∙Select the right edge of the large hole (Curve ID = 101) and click OK to confirm your selection.

∙In the Center – Define Location on CSys X-Axis dialog box, click the Method button again and select Locate from the menu.

∙Since the default “snap mode” for Femap is set to screen, right-click your mouse in the graphics

window and select Snap to Point from the pop-up

menu.

Select the start point on the bottom of the arc as the locator for the vector defining the X-axis of the

coordinate system and click OK.
