    Natural frequency analysis

    In fact I use the same excitation of 0.25G, but the graph I sent at 17:19 on the 18th Nov was an example I followed. My dimensions are: (100 x 100 x 200) mm I fixed one end and put my excitation at the same end. I look at 1 node at the other end. In my graphs, x axis is the frequency and y axis...

    Natural frequency analysis

    I think I have something better now. I did my 3 axis back to back on the complete frequency range and it gives me this: My natural frequencies are suppose to be: Does it make sens or not at all? By the way thanks for your answers...

    Natural frequency analysis

    When I but my excitation of 0.25G in the Y axis I get this for the accelaration vs frequencies: When I put the excitation in the X axis I get this for acceleration and displacement: The peak is at a frequency of 190 Hz instead of 211 Hz as I was expecting with the X excitation and I dont...

    Natural frequency analysis

    I am not sure what you are asking. Where do I have to ask NASTRAN to do it? Because I am using FEMAP for my study. Is it in the Manage window that we ask this? Thanks

    Natural frequency analysis

    I ask for the displacement in output request from «Manage» of the study. And in my plot I asked for T2 translation since my excitation is in this axis.

    Natural frequency analysis

    Hi, I got my natural frequencies from Siemens NX and went in FEMAP to obtain the plot of my peaks at those frequencies. The problem is that I am new to this and I don't know how to get a good plot. I watched a lot of tutorial but nothing is working. Here's a description of my analysis: - A...
