    Simulation Buckling Results

    Joseph Contreras

      Using SolidWorks Premium 2015 x64, service pack 5.

       

      I am trying to use the Buckling study to analyze a simple cylinder model, and am not understanding the results.

       

      What is the Mode Shape/Amplitude Plot showing? Looking at the List Buckling Factor of Safety (see image) option, it gives me a FOS that is matching with classical hand calculations, but I do not know what the plotted result is.

       

      Also, according to the documentation for Output of Linearized Buckling Analysis and Performing Buckling Analysis, it appears that the output should be displacement and/or deformation. I could not find any mention of a mode shape plot in the documentation. Finally, I do not have these two (displacement/deformation) plots available as potential charts; the only chart option that I have is the Mode shape/Amplitude plot.

       

      My two questions are what is the Mode Shape/Amplitude Plot, and why don't I have the option to create a displacement/deformation plot?

       

      Any insight someone may have is greatly appreciated.

          Hi Joseph,

          The results being output from a Buckling study are neither displacement nor realistic deformation.  The results that output from a Buckling study (or Frequency study) are a qualitative illustration of how the model will fail in a buckling mode.  Truthfully the numeric values of these plots have no meaning.  Pretty much the only kind of information that you can deduce from the plot is that a particular buckling failure bent "sorta in this way."
