To create generic linear impact model that even non-CAE engineers can use to run studies.
Six files needed for input.
1. Master file : The first level file with five included files.
2. Airbag file : The airbag file with "pab" in the file name.
3. Inflator file : The inflator file with "inflator" in the file name.
4. Impactor file : the impactor file with "impactor" in the file name.
5. Windshield file : the windshield file with "windshield" in the file name.
6. Test Fixture file : the test fixture file with "test_fixture" in the file name.
With this application, user can make basic changes, such as airbag location and angle, tether length, impactor mass and velocity. Or replace certain component with new one. Or output the modified model. Or run LS-Dyna with the modified model as input. Or plot the result.
Setup: Overall setup
1. Component assignment.
2. Output directory.
3. Solver path.
4. Parameter to run solver.
5. Plot template setting
Modify: Four kinds of modification allowed.
1. Component replacement.
2. Location and angle adjustment.
3. Other parameters adjustment.
4. Kinematic curve display and replacement.
Output: Write a copy of model to output directory.
Run: All in one button.
1. If not outputed, it will output a copy of model.
2. Submit model to solver.
3. Reading result and plot according to template
Post: Plot impactor response curves.
Sample : show how AIMS work.

Browse : Browse a new airbag file to replace current one. X : Translate airbag in X from its current position Y : Translate airbag in Y from its current position Z : Translate airbag in Z from its current position Module Angle : Rotate airbag about Y axis. Effective Length : Un-stretched length of tether set to a large value to simulate no tether. Plot : Plot fabric permeability curve x: gauge pressure (Pa) y: dynamic permeability (m/s). Replace : Replace fabric permeability curve x: gauge pressure (Pa), y: dynamic permeability (m/s). Setup : See Function Segment. Output : See Function Segment. Run : See Function Segment. Post : See Function Segment. Anim : Switch between plot result and d3plot result. Done : Exit AIMS interface. |
