SEXAMPLE: CREATING A MODEL OF AN OVERHEAD HOIST WITH ABAQUS/CAE

The instructions for the examples discussed in this manual will focus on using the Model Tree to access the functionality of ABAQUS/CAE. Menu bar actions will be considered only when necessary (e.g., when creating a finite element mesh or postprocessing results).

Example: creating a model of an overhead hoist with ABAQUS/CAE
This example of an overhead hoist, shown in Figure 2–5, leads you through the ABAQUS/CAE modeling process by using the Model Tree and showing you the basic steps used to create and analyze a simple model. The hoist is a simple, pin-jointed framework that is constrained at the left end and mounted on rollers at the right end. The members can rotate freely at the joints. The frame is prevented from moving out of plane. A simulation is first performed in ABAQUS/Standard to determine the structure’s static deflection and the peak stress in its members when a 10 kN load is applied as shown in Figure 2–5. The simulation is performed a second time in ABAQUS/Explicit under the assumption that the load is applied suddenly to study the dynamic response of the frame.

EXAMPLE: CREATING A MODEL OF AN OVERHEAD HOIST WITH ABAQUS/CAE

For the overhead hoist example, you will perform the following tasks:

• • • • • • • •

Sketch the two-dimensional geometry and create a part representing the frame. Define the material properties and section properties of the frame. Assemble the model. Configure the analysis procedure and output requests. Apply loads and boundary conditions to the frame. Mesh the frame. Create a job and submit it for analysis. View the results of the analysis.
