Algor simulation 2011 (Frecuency Response) HELP please

[psredondos]

Hi everybody. I've been doing some research for my tesis at university about Foundation for vibrating machines. I'm using Algor Simulation 2011 and have modeled some foundations. So far I've run a Natural Frecuency analysis and a Static Stress one. The fact is that, to round up all my work, I want to run a Frecuency Response analysis but I really don't know how to do so. To be specific, I have 4 nodes of my model that should be excited al the same frecuency but with different loads and I have no idea how to do it. I figured out how to load nodes with the same force at different frecuencies, but couldn't figure out how to do it as I mentioned before. I also need to know what does the "Loads of the same frecuency" box stand for, I mean, if I introduce different frecuencies and I check this box, which frecuency does the software use??

Thank in advance and sorry for my awfull english,

Pablo Soler

Hi, im trying to do the frecuency response but i dont know if im making wrong the steps, when i run the analysis it always say that any displacement where found show one error. I find the natural frecuence of my system by doing the natural frecuency modal. Can u make a video or explain to me the steps to make it? I need to have the graph with the harmonics frencuencys for my thesis. If you have info or a video or the excat steps, pls tell me. danvel37@hotmail.com. Sorry for not answering your question. Take care.
