I have a simple question to ask...
I am trying to silmulate a analysis of Base frame of a flat bed trailer. I have uploaded the pic.
As in the picture i have fix the king pin location from front & axle location from behind. u can see the green arrows to see the fix location.
and then add a load at appropriate position.
But after running the simulation, what i find that stress is developed near axle position where i have fixed the assembly.
But in real life normally base frame has more damage at goose neck position.
What i am doing wrong? do iahve to take the suspension type boundary conditon or what.
