I am currently involved in performing dynamic analysis of particular
assemblies and working in ansys workbench 12.0. Currently I am stuck with a
problem, while performing harmonic analysis I need to input displacement as a
tabular function of frequency but inspite of all my efforts could not find a
solution to this problem. Also the assembly is connected to the vibrating base
via mounting feets. Now in that case should the displacement field be applied
to the holes of the mounting feet or the entire base plate of the assembly that
rests on the surface of the vibrating base.Also how to obtain plots of
accelaration v/s frequency during post processing is also one of my concerns.
Any one who has knowledge of the same, kindly share your experience. Your
ideas and suggestions are more than welcomed in this regard.
