Hey Folks
I would like do a vibration analyses on a plate (made of Steel), with encastered boundarys and a dynamic force which is attacking in the middlepoint. The force excitiation is harmonic (sinus, cosinus Fourier ect.) I would afterwards display the 'Time - Displacement - Graph' from one Point in HyperGraph and the whole displacementfield in Hyperstudy.
To build up the modell is my biggest problem. I have tried the 'Transient (Modal)' loadstep. I have used DAREA as force and the excitation was given by a TABLED1 (importet). I put this together with a TLoad and created a TStep (Time). The Solution was not that good because the results were very shaky.
My Questions are:
- is there any possibility to perform a operational vibration analyses with Radioss in Time domain
- if Yes, which kind of loadstep must I use to get a time - harmonic vibration (I have found nothing how to use TStep Fourier)
- can I define the excitation via a 'Curve' or is TABLED1 the only way?
- which kind of load must I use (TLoad/RLoad/DLoad)
Thank you for your help.
With kind reagards
Alex
