Combination of Sinus and Displacement ?

[yassou]

Hi every body
I have an analytical part, and i want that part vibrate in sinus manners meanwhile move down toward the second deformable part.
Now, how should i did something like that?
with best regards.

Not sure I understand exactly, but perhaps this might give some ideas. Use implicit dynamics, with an enforced displacement on the moving part and a sinusoidal time varying force/pressure. These two should ideally be applied at different locations, so they do not cancel each other out. Finally a contact can be used between the moving part and the second part in case they will start touching at some point

Hi Erik Panos Kostson
Thanks for Reply.
My amplitude should something like This:

Now how can i make my Analytical Part move like This?
with best regards.

Define an amplitude curve in abaqus cae describing the graph you showed, then define a boundary condition for displacement and assign this amplitude data to it. The following link covers boundary conditions that vary with time: Link

Amplitude curves are defined:Link

Just create two tables (sinus and linear movement) in Excel, create the sum of the two and bring that as amplitude to Abaqus.
