This page will <\/span><\/a>introduce the dynamic analysis function (frequency response analysis and transient response analysis) of Jupiter-Post.<\/a><\/span><\/p>\n

 <\/p>\n

1. Introdution of the dynamic analysis function of Jupiter-Post<\/span><\/h3>\n
    \n
  • You can perform frequency response analysis and transient response analysis on the solver’s real eigenvalue analysis results.<\/span><\/li>\n
  • It is possible to obtain a large number of response results at a very high speed by calculating the response by the modal method.<\/span><\/li>\n
  • It supports ABAQUS, ADVC, Nastran, and SunShine-Solver result output formats.<\/span><\/li>\n<\/ul>\n

    2. Frequency response analysis function<\/span><\/h3>\n
      \n
    • It is a frequency response calculation by the modal method.<\/span><\/li>\n
    • You can select multiple vibration points and response points from the GUI.<\/span><\/li>\n
    • The calculation is very fast, and even a large number of response points can be calculated in seconds.<\/span><\/li>\n
    • The exciting force setting conforms to the Nastran RLOAD2 format. You can also input and output in the Nastran bdf file format.<\/span><\/li>\n
    • Check the result by outputting the response result to an XY graph or CSV external file.<\/span><\/li>\n<\/ul>\n

       <\/p>\n

      2.1 Setting vibration conditions<\/span><\/b><\/h4>\n
        \n
      • You can easily specify the vibration point from the GUI.<\/span><\/li>\n
      • The exciting force conforms to the Nastran RLOAD2 format.<\/span><\/li>\n
      • It also supports the input of frequency tables of Amplitude and Phase.<\/span><\/li>\n
      • It also supports local coordinate system references.<\/span><\/li>\n
      • Unit vibration and centrifugal force can also be set.<\/span><\/li>\n<\/ul>\n\n\n\n

          \n
        • You can easily specify the response points from the GUI.<\/span><\/li>\n
        • Execute the calculation by specifying the attenuation coefficient (changeable by the frequency table) and the calculation frequency.<\/span><\/li>\n
        • Results can be specified from displacement, velocity, acceleration and stress.<\/span><\/li>\n
        • It also supports the output as a result of referencing the local coordinate system.<\/span><\/li>\n<\/ul>\n

          2.3 Response function output<\/span><\/b><\/h4>\n
            \n
          • The calculation result is displayed as an XY graph. Based on the Bode diagram that displays Amplitude and Phase at the same time, you can change it according to your needs.<\/span><\/li>\n
          • You can output a file in CSV format from the Chart ribbon, and there are various functions such as changing the graph format, displaying \/ hiding numerical values, and displaying \/ hiding each result curve.<\/span><\/li>\n<\/ul>\n
