Assignment 7-Side Pole Crash Simulation Challenge
Objective- side impact test is an important safety check for the vehicle and it is performed in this assignment.
Apart from this there are other output requests like:
- Sectional force in the cross member.
- Intrusion at B pillar, hinge pillar and fuel tank region. Provide recommendations on what can help to reduce Fuel tank intrusion.
- Peak velocity of an inner node of the door.
- Energy plots
Output1- sectional forces in cross member
Section-1:
Fx:
The magnitude of maximum total Fx force is slightly less than 0.5kN.
The magnitude of maximum total Fy force is roughly 1.5kN.
The magnitude maximum total Fz force is slightly less than 0.4kN.
Section-2:
Fx:
The maximum total Fx force is slightly less than 0.5kN.
Fy:
Fz:
Output2- intrusion at B pillar
Leftmost spring in the image among three represents this case.
The maximum intrusion is slightly less than 475mm.
Output3 – intrusion at hinge pillar
The maximum intrusion is slightly less than 475mm.
Output4 – intrusion near fuel tank region
The maximum intrusion is roughly 515mm.
Output5 – velocity of node 337773
The maximum node velocity is slightly less than 10m/s.
Output6 – energy plots
The maximum internal energy is roughly 14000J.
The maximum contact energy is roughly 550J
The maximum hourglass energy is slightly less than 13J.
As it can be seen from the graph, the hourglass energy losses are minimal and contact energy is also less throughout the simulation. The maximum forces, deflections and energies can be studied to prepare failure proof model of the product.
