Geometry cleanup and shell meshing of automotive hood

Aim:- To perform geometry cleanup, 2D meshing, quality check, and fixing the errors of the automotive hood model.   Procedure:-   The hood model was downloaded and opened in ANSA Topology of the model was checked (TOPO<FACES<TOPO).   Few geometric errors were diagnosed and they were fixed manually…

Objective:- To perform frontal crash analysis of a BIW substrate against a rigid wall at 35mph.   Following steps are followed:- Check the unit system and either follow[Mg mm s] or [Kg mm ms]. Create an appropriate interface, friction 0.2, and recommended parameters. Make sure of no penetrations and intersection.…

Objective:- To set up the simulation for the side crash of a reduced BIW substrate against a cylindrical pole.   Following are the steps followed:-   Check the unit system and either follow [Mg mm s] or [Kg mm ms]. Create an appropriate interface, friction 0.2, and recommended parameters. Make sure of no penetration…

Objective:- To run the simulation for a crush tube against a rigid wall & study the changes by varying a few parameters and notch position as per the following sub-cases. Run the crash tube model as it is. Change the Inacti=6 and run. Create the type 11 contact and run. Remove both notches and remove boundary conditions…

Objective:-To simulate and compare the results of punching of a rigid ball against a rupture plate using different material laws using the following cases. Case 1;-Simulate the model without making any changes.[(Eps_P_max) and failure johnson cards enabled].     Case 2:- Simulate the case, 1 model, by putting…

Objective:- To compare results of crashing of a rail against a rigid wall with base shell properties & upgraded shell properties.   1.Using the crash beam file from the previous assignment, change the runtime to 55 ms. Change the number of animation steps during simulation to a minimum of 25 and a maximum of 60.…
