Ok well to many this is going to seem like a really stupid question I am sure :/
I need to calculate Maximum Torsion in a chassis, to start with i want to look at collisions or rough terrain;
Assumed 3g bump applied diagonally
Assumed bump 150mm high
Overall factor applied 1.5
Giving an upward acceleration of 4.5g at the wheels
Opposite pair of wheels assumed to be 1g
As i understand this if a car hits a bump 150mm high I am assuming a 3g force is applied. I assume it is applied diagonally due to the impact location on the wheel? or the acceleration of the car?
I am unsure how the overall factor of 1.5 is decided? what is the 'overall factor'?
I assume by opposite pair of wheels it refers to the rear? but could this also be the passenger side if the impact was on the drivers side?
I apologies if this is like asking you guys to suck eggs however, I am comfortable designing and building to specified parameters and have an ambition to understand the stress calculations involved in creating these parameters. I would greatly appreciate any help explaining what is happening here in a dummy's guide?
