Introduction Simulation The ANSYS Workbench represents more than a general purpose engineering tool. It provides a highly integrated engineering simulation platform. Supports multiple multi-physics engineering solutions. Provides bi-directional parametric associativity with most available CAD systems. This exercise is designed to introduce you to a number of the various engineering simulation capabilities of the ANSYS Workbench

Exploring Simulation The methods taught in this tutorial apply equally well to both attached CAD and DesignModeler files. For the purposes of this tutorial we will be using a stable and previous saved version of the files produced in Exercise 5 of this tutorial. Again if you have not completed any or all of the previous exercises contained in this tutorial you should do so now.

Examining Simulation

Select and enter the Projects Simulation Note: Our simulation includes: A plate mounted on a post. The post is mounted on a moving platform. Aircraft, ship, oil rig platform, etc. The equipment (not modeled) is mounted by four mounts on the plate. The applied (remote) loads (forces) include: The equipment weight Force due to acceleration in X & Y 2006 ANSYS, Inc. All rights reserved.

Step 6A Viewing Load Steps

Note: You know have the ability to insert tabular data for Accelerations for each of your 8 load steps

2006 ANSYS, Inc. All rights reserved.

32

ANSYS, Inc. Proprietary

Note Applying accelerations For purposes of this example we will apply our accelerations based on global X, Y and Z coordinates. In more realistic examples these accelerations would be based on more realistic locations of our masses based on the centers of pitch, roll, etc. of the structure on which your model is mounted
