constant amplitude loading to the tip of the cantilever beam

constant amplitude loading to the tip of the cantilever beam

constant amplitude loading to the tip of the cantilever beam

(OP)
i have a quick question, which i searched within the web and cannot find.


i am using ansys v10 multiphysics  to study a cantilever beam. i am a new user to ansys but not to FEA
i am trying to apply a constant amplitude load with a zero mean load to the tip of the cantilever beam which will
cause the beam to oscillate in a sinusoidal  fashion. Basically R=-1    (fmin/fmax )
I am assuming a harmonic analysis. When i go to apply the load i see i can set it at constant, but how to i make the load to move in compressive
and tensile manner in order to cause this type of oscillation.

Can you suggest anything or point me to an example which will  give me a starting point. im really lost

regards
Vincent

RE: constant amplitude loading to the tip of the cantilever beam

Vinny, harmonic analysis is sinusoidal in loading by definition.  Hence, you will see the fully reversed load that you wish to achieve.  Read the documentation section on this subject.  It's quite helpful and will answer a lot of your questions.
