How i can model a spring element with axial and radial stiffness in Optistruct?
Please Help?
As per my understanding PBUSH element have K4,K5&K6 for rotation stiffness not axial stiffness.
Please explain.
Thanks

Someone please reply asap.. Thanks
Yes K4,K5&K6 is for rotation stiffness.Please note, Rotational stiffness values are input based on rotations defined in Radians.
Thanks for the reply.
We want to model a composite (Rubber) hose as a spring (BUSH) element.
As, hoses are cylindrical (means they have axial and radial stiffness; Best to define in cylindrical co-ordinates) and curved (Not in single Plane). So, i have to model them with multiple bush elements (Each element in different Plane; best to define in cylindrical co-ordinates).
So, i want to know which bush element is most suitable for my application in cylindrical co-ordinates.
Please explain the procedure to define also.
I am attaching here file too showing one model as hose and one model as CBUSH (Just for explanation).
Unable to find an attachment - read this blog
PFA old video of Bush element creation.
Thankyou rahul.
While defining CBUSH element in Cylindrical co-ordinates,
does
r refers to K1
z refers to K2
t refers to K3
or some different.
Otherwise can you reply me in my model by creating CBUSH elements with axial stiffness 19680 and radial stiffness 10?
Please revert.
Hello everybody,
@hemanshu
I need help regarding same. How u get stiffness value of composite rubber hose.
@Rahul
Is it possible to realize the crimp joint in better way.
any help
