Need Help Simulating Shaft Torque

[jonno000]

Hey guys,

I'm a new user here looking for some help with FEA (Simulation Multiphysics 2012). I attached an image so you can visualize what I'm trying to do. Basically I have a shaft supported by two bearings, and a belt sheave driving a centrifugal fan. I have split the faces on the shaft and I am applying a pin constraint at the bearing locations. I figured out now to apply the tangential loads, but I am unsure how to apply the torque.

I would appreciate any advice you guys have, thanks in advance.

Hi,

There is an exercise you can try:

http://help.autodesk.com/view/ASMECH/2015/ENU/?guid=GUID-3E4DAC24-24ED-446B-B5FD-BBAFEA32FB58

Also, there is a previous discussion thread, type in torque on the search bar.

If I remember correctly, the software had an update last year to place a torque on a bar fairly easily (but you have 2012 so perhaps not of use), I will take a look when my current analysis stops,

Regards,

Mike

Thanks for the info Mike, I'll take a look at the exercise and the previous discussion.

One thing I didn't mention is this shaft is rotating at about 3000 rpm and the belt drive is driven by a 31 HP engine. However, if I can simulate the shaft statically with equal and opposing torques at the areas of interest (sheave and fan), it will be good enough for my current needs.
