Assignment 6-Frontal Crash Simulation Challenge

Frontal Crash Simulation Challenge

aim

To 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 intersections.
Correct rigid bodies if any issues.
Create a rigid wall with friction 0.1.
Compare the model weight with the full-scale 300k nodes model and use added masses to reach the target weight of 700kg while getting CG about the required range.
Initial velocity 35 mph.
Use a model checker to ensure good quality.
Time-step :0.5 to 0.1 microseconds.
Run 80 ms.

output request

Sectional force in the rails at the location of indicated node 174247.
The axial force received on the rails from the 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.

procedure

to import the model into the graphic area
we have to check the unit
go to model - cards - begin card - check the units
now we have to create the group
dlt the old grps data
and create the new TYPE 7
and then enroll the all details in the type 7 data
go to model - groups - create type 7 - enroll the type 7 details
after creating the group
we have to create the rigid wall
go to solver - create -rigid wall - enrol the details
now we have to create the cross-section
go to solver - create a frame -mov-select the nodes
now we have to select the nodes in the triangle form
in the same way we have to create the cross-section in the pillar,rail, bumper section, shotgun
create the components in both left and right side
after creating the cross-section
now we have to give the section
we have to check mass of the car
and mass to balance the weight of the car
to check the mass of the car
go to tools - mass details - mass,cog
and check that
if the mass got more or less than the actual value have to reduce and increase by ADMAS
by grnode
now we have to check the model checker and then we run the simulation
after check the model now we have to run the simulation
now we have to plot the graph of all the things what we are doing
