CADFamily.com: ANSYS AUTODYN-Bird Strike

7/06/2011

Workshop Goal and Procedure

Goal:

Model a bird strike on an aircraft wing

Procedure:

Set up the problem in Explicit Dynamics (ANSYS)

Transfer the setup to AUTODYN

Convert the Bird Part to use SPH nodes

Run the analysis in AUTODYN

Step 1 – Start Workbench

Start ANSYS Workbench and follow the sequenced steps using the

abbreviations shown below:

–DC = Double Click with Left Mouse Button

–SC = Single Click with Left Mouse Button

–RMB = Right Mouse Button Selection

–D&D = Drag and Drop = Hold Left Mouse Button down on item while dragging it

to new location and then release it (i.e., Copy or Move)

Throughout these Workshops, the procedures shown are not always the

only way to accomplish the desired tasks, so feel free to investigate other

methods via the documentation when outside of this course

.The workshops consistently use RMB in the Outline tree to access options

whenever possible

.Often these options can also be accessed through the “Context” Toolbar

.Sometimes these options can also be accessed using RMB in the View area

2.a Create an Explicit Dynamics (ANSYS) Project

Step 2 – Initiate an Explicit Dynamics (ANSYS) Project

2.b Select MKS for the Project Units and request Native Applications in Workbench have their values Displayed in the Project Units

Step 3 – Define Engineering Data Material

3.h Temporary fix

Return to Engineering Data and enter “0” for the Shear Modulus for WATER2.

(This is an error that will be fixed in the next release)

Step 4 – Import the Geometry

4.a Import the geometry database bird_strike.agdb as shown below

Step 5 – Edit the Model in Mechanical
