2D centrifugal force

Recommended Posts

Hi...


 


I am a new user of Hyperworks.


I want to analyze the centrifugal force and the depending stresses and displacments.


My part is a little bit like a CD. I want to this in 2D. 


 


My Questions>


 


1. Which element should i use?


2. How to create the constrains?


3. How the creat a cylindrical coordinatesystem?


 


Best regards

Hi Alex,


 


1) Since you want to model it 2D, better use shell elements to model.


2) You may consider constraining at the center of the rotation and apply a centrifugal force using RFORCE in OptiStruct


3) You can create systems using Systems panel


go to Analsysis>> Systems and change system type to Cylindrical
