Hi Experts,

 

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.

 

please advice...
