Thanks for making this great and in depth tutorial! It's hard to find good, detailed Inventor Nastran videos like this that go beyond the basics of linear or even nonlinear statics!

That was very informative. Thank you very much for creating this video.

Thank you for a very informative presentation.

very nice tutorials sir....I am glad someone is doing this kind of stuff. I have a quesion what about vibration fatigue? I was doing the test (because inventor nastrasn offers that option ) but it required to fill a table. I would like to ask you politely if you can expand this tutorial with that fatigue analysis. Kind regards

this is a great tutorial. I'm interested in the vibration exposure data PSD for off-road use. You mention there is MIL-STD data available for this but MIL-STD-810 G specifically says no data is available fo estimating ground vehicle vibration levels (page 514.6D-19) - can you confirm this? Cheers.

Very good presentation. Two question please 1. is remote mass considered in modal analysis or just the weight of the frame is included in modal frequencies? 2. how did you verify your results and ensure they are correct and can be relied on? thanks,

One more question please: if you have a load acting as 10 lb @ 50 Hz to the frame (some unbalance load) how do you consider the load? how do you define that the load is acting at 50 Hz? thanks,

How did you put those constraints? I'm highly struggling with them
