Exercise 2: Define Boundary Conditions and Loads for the Head and A-Pillar Impact Analysis
In this exercise, you will define LS-DYNA boundary conditions, loads, and contacts in Engineering Solutions. Also, you will set up the boundary conditions and load data for a LS-DYNA analysis of a hybrid III dummy head impacting an A-pillar.
Load the LS-DYNA User Profile
In this step, you will load the LS-DYNA user profile in Engineering Solutions.
- Start Engineering Solutions Desktop.
- In the User Profile dialog, set the user profile to LsDyna.
Retrieve the Engineering Solutions File
In this step, you will open the Engineering Solutions model file.
Create a Node Set
In this step, you will create a node set, *SET_NODE_LIST, which will contain all of the nodes in the head component of the model.
Define the Velocity
In this step, you will define the velocity for the model.
Create a Load Collector
In this step, you will create a load collector for the constraints to be created.
Create Constraints on the Pillar's End Nodes
In this step, you will create constraints on the ends of the pillar component of the model.
Define a *SET_SEGMENT for the Slave Entities
In this step, you will create a new contactsurf on the pillar element of the model.
Define a *SET_SEGMENT for the Master Entities
In this step, you will create a contactsurf on the head component of the model.
Create a Engineering Solutions Group
In this step, you will create a Engineering Solutions group with the SurfaceToSurface card image.
Add the Slave and Master Contactsurfs to the Engineering Solutions Group
In this step, you will add the slave and master contactsurfs to the Engineering Solutions group.
Edit the Group card image
In this step, you will define the automatic option for the group in Engineering Solutions.
Review the Group Master and Slave Surfaces
In this step, you will review the master and slave surfaces for the group.
Save Your Work
In this step, you will save your work in Engineering Solutions.
