Assignment 7-Side Pole Crash Simulation Challenge

                                    Side Pole Crash Simulation Challenge

AIM

• Check unit system and either follow [Mg mm s] or [Kg mm ms].
• Create appropriate interface ,friction 0.2 and recommended parameters.
• Make sure of no penetration and intersections.
• Create rigid wall with friction 0.1 as per referance model.
• Compare the model weight with the referance model and use added masses to reach target weight 700kg while getting CG about the required range.
• Initial velocity as shown in picture.
• Use model checker to ensure good quality.
• Timestep :0.5 to 0.1 microseconds.
• Run 80ms.

OUTPUT REQ

• Sectional force in the cross member.
• Intrusion at B pillar,hinge pillar and fuel tank region.Provide recommendation on what can help to reduce Fuel tank intrusion.
• Peak velocity of inner node of the door.

PROCEDURE

• To import the model in the graphic area 
• 
• after that we have to check the units of the model
• and then we have to dlt the all groups and create the TYPE 7 only
• 
• and enrol the details in the type 7
• 
• and then we have to create the rigid wall in the side door
• this time we have to create the crash in the side pole 
• so create the cylindrical type of rigid in side door
• 
• 
• after that, we have to create the crosssection in the middle rail
• go to solver - frame - mov 
• 
• select any three nodes in the form of triangle shape 
• and then create a local coordinate system
• 
• after that we have to create the cross section 
• 
• and then we have to create the intrusion for the model
• we have to create the skew in 3 area 
• b piller,petrol tank and hinge 
• 
• after that we have to check the cog
• 
• if we want to increase the weight of the car or reduce 
• then we want to increase the mass of the car what side we want 
• 
• 
• and then we have to check the cog
• if it correct then we run the simulation 
• other wise we have to keep the cog perfect 
• 
• after complete the simulation 
• we have output like this 
•
