modulo fea

[PabloPicasso]

Hi.

I've just started using the fea module.

I am trying to calculate the rotation angle of a frame subjected to a tocent force on one of the sides. I tried to use the stress module analysis of inventor 2010 and get the simulation of the deformation of the piece with color scale and maximum deformation distance.

Question: How do you calculate the precise distance of moving one point (in my case the angle where I applied the force) ?

with the measuring instrument there is no way to trace a dimension between the initial and the final position in the result of the analysis.

no fea expert....

However, I solved, so I explain briefly how it is possible to do so for those in the future who needed it.

using the probe tool you can get the Cartesian coordinates of a point in the deformed element. with a bit of mathematics you can then calculate the distance and angle of shift.

Unfortunately, automatically, inventor does not provide anything more.

from today you are named "expert fea" for merits obtained in the field
Other jokes: Congratulations.

I confirm that the angle of rotation does not automatically give you, you have to calculate it.
the moving instead with the probe you can read it in all directions in the travel folder.

I add that I have seen that the 2011 version has a new feature called "frame stress analysis" made specifically for frames.

using that of 2010 you can only do mesh-based analysis and for any modification it takes 30 minutes to process the analysis.

the frame stress analysis is based on the concept of the "beam analysis" i.e. the frame pieces are assimilate to 2d lines and the processing is much less laborious. It has been noted that this type of analysis, if applied only to frames, does not generate substantial differences in results compared to traditional analysis.
