Here, you will set up a car model and perform a roof crash analysis using Hypermesh and solve the model using RADIOSS solver. The model is checked for intersections and penetrations. Errors are debugged and the model is simulated.
Step 1 - Geometry manipulation
Step 2 - Contact Definition
Step 3 - Apply Boundary Conditions and Run the Simulation
Step 4 - Post Processing using HyperView and HyperGraph
In this project, you will work on a frontal crash analysis of a reduced neon car model. You will do the following in this project,
Initial checks like intersections, penetrations in the model and add suitable mass to the model
Creation of rigid walls, proper contacts and assign overall velocity for the model
Creation of accelerometer, sections for determining section forces and providing springs to determine the intrusions for the model
Create suitable output blocks and the manipulation of engine cards.
Debugging errors and warnings
Visualizing the results in Hyperview and cross plotting the results in Hypergraph to determine the overall strength of the roof.

In this project, you will be setting up the case for roof crash analysis for a reduced neon car model. Here, you will import the model, do initial penetration checks. You will also import the impactor separately and position it in the desired location. Create proper contacts for the car model and contacts between the roof and car. After that, you will create collectors to fix the suspension points of the car, collectors for fixing the impactor in space, and assign proper boundary conditions for the impactor. The model is checked for any errors and warnings, if any present, those are debugged. To obtain all the results, output blocks are created for the said conditions, and the engine cards are manipulated to our requirements. The output is visualized using Hyperview and to determine the strength of the roof, cross plot is created in HyperGraph. The result from the HyperGraph is compared with the roof crash standards.
