Concentrated sinusoidal load (pt=700*sin(2*pi*fl*t)) in abaqus

[nlgarcia]

Hello!
I am new in abaqus, I am trying to obtain the maximum acceleration at steady state at the mid point in a beam
The characteristics are:
- Concentrated sinuosal load pt=700*sin(2*pi*fl*t) in the middle, 1<fl<6.
- E= 140 GPa
- D=4000 kg/m3
-long span 15 m, it is a box cross section with height 0.16m, Thickness 0.04 m and width 0.16 m
Can you help how can I obtain frequencies and acceleration?

I have attached the model that I am doing in abaqus.

Many thank you

SSDs use a cosinus function by default and act in the frequency range, not in time. Have a look into the manual.

Thanks for your reply. I will try that.
