Centrifugal forces

Recommended Posts

Hi, 

I would like to apply a centrifugal force to my model so I created a loadcollector with card image RFORCE but I don't know what the fields refer.

I discovered that A refers to angular veolcity, RACC to angular acceleration, but what do the fileds G, CID, R1, R2, R3, IDRF refer to?

Hi

you can find it in optistruct reference help

G - origin of rota vector

CID - coordinate system of vector

R1R2R3 - components of vector

IDRF - id of element set applied this force

Hi

enter menu Help of hypermesh

 

But I see it is very slow while browsing help documents, especially from v2017

 

 So I usually enter folder <install dir>\help

and then use window search tool to search files, just enter "rforce" in search box, the html file will appear soon

How to calculate R1 R2 and R3? I didn't fullt get it.

They are the versor components of rotation axis. For example : rotation axis parallel to z direction -> R1=0 R2=0 R3=1. In general you can use a  vector parallel to rotation axis.
