Assignment 6-Frontal Crash Simulation Challenge

Objective:

• Create interface type 7 , with friction 0.2 and recommended parameters.
• Make sure of no penetrations and intersection by checking in Tools>Penetration check.
• Create rigid wall with friction 0.1. Provide proper dsearch value with cordinates.
• create initial velocity 35 mph=15.64m/s and assign it to car body.
• Use Tools>model checker to ensure good quality.
• For time-step 0.1 microseconds edit ENG_DT_NODA card Tmin value to 0.001.
• For run time to be 80 ms edit ENG_RUN car Tsop=80.

Output Requests;

• Sectional force in the rails at location of indicated node 174247.

• Axial force received on the rails from bumper.

• Shotgun cross sectional forces.

• A pillar cross section.

• Acceleration curve received on the accelerometer at base of B pillar (on B pillar rocker).

• Intrusions on the dash wall 66695,66244.
