centifugal load
centifugal load
(OP)
hi,
iam analizing a balde of an exhaust fan .And for this i need to aplly centifugal load.
i have done in the following way ,
1.created a cordinate system at axis of rotation .
2.given angular velocity in y direction(blade rotates in X-Z plane).
3.and also given density for the model in material.
is this a correct approach?
or do i have to give centifugal load as weight force by giving some transitioanal accleration?
thanks in advance for ur suggestions.

RE: centifugal load
Just to be on the safe side, make a little experiment with PATRAN with a simple beam which can be calculated by hand, and see if the hand calculations are similar to the results you are getting from NASTRAN.
