Hi expert,
I have a question "How to plot the graph about vibration amplitude, angular velocity, and frequency of the engine based on MBD results"
Thanks.
Hello Brian,Here you can find a dedicated tutorial on how to create a waterfall diagram of Force-Frequency-RPM (HG3D-1000: Define Waterfall Plots (altair.com)). As the tutorial describes, you'll need to first create two plots Force-Time (in your case displacement-time) and RPM-Time. Then in a new page you'll have to create a 3D chart and from the waterfall diagram panel you can select the precious curves. Hope this helps!Best regards,Orestis.
Hi @orestes ,
I need a plot vs frequency, so I need a plot vs time and convert it to frequency, right?
Thanks
Hello Brian,waterfall diagram tool in 3D chart suite will perform the FFT for you. You will just need to pick the desired values in comparison to time.Best regards,Orestis.
Hi @orestes
The curve 1 is displacement, the curve2 is angular velocity.
When the response is curve 1, the input is curve 2, The force in the 3D plot is displacement right?
Why is it named force?
Hello Brian,force label is set by default but you can change it by double clicking on it.Best regards,Orestis.
