For experimental analysis I'm using lms test lab software. There for frf we get graph of g/N against frequency. To validate the results of numerical and experimental analysis I want the same graph in ansys. But I'm getting amplitude against frequency in ansys. How should I change my process to get results?
Make the use of relation a(i) = w(i)^2 * x(i) between displacement (x) and acceleration (a) in harmonic motion. Where i = 1, 2, 3 . .
Hope this helps
Hi Nayan,
In Workbench to get a FRF graph you should applied a force to structure. LMS Test Lab calculate Response as "g/N" which means gravity (9.80655 m/s^2) devided by "1 Newton" force. You should give a "1 Newton" force in your simulation, afterward you should plot FRF graph as acceleration (not displacement). The last step devide the LMS test results by 9.806655 to get similar unit as in ANSYS. You are ready to compare your results.
Best Regards...
