Linear Static Analysis.

Hi,

I have attached a running board linear static analysis. I’m getting a deflection of about 0.0053mm deflection. But in real scenario they are experiencing 1 to 5mm deflection. Instead of applying load on REB3 if I applied load as a point load (single point in the middle of 200 x 80 mm) I’m getting deflection of 3mm. So what should I do here? Should I use REB3 or point load for a cross section of 200 X 80 mm

Thanks,

Vijay

    Hi George

    Just a thought, while stepping on running board the load will be concentrated on just stepping (foot) area. Try giving UDL on that foot area using RBE2 as RBE2 will act as UDL.

    Hi Nachiket even I tried using RBE2 elements still the results are unchanged...

     

    Thanks

    Hi,

    How the load and boundary conditions was applied in physical test? Was the load applied through a ram-actuator or a person standing on the running board as both can have different boundary conditions?

    Hi,

     

    Can you check the area of the load applied?

    Are you dividing the load by any chance by number of nodes?
