3 direction spring

Altair Forum User

Dear all

I have used F-D curves to define a cbush element in optistruct. Is it possible to creat similar element in radioss? I don't know how to define Bush element

in radioss. could you help me?

I used three KN-line to define the Pbush element. how to convert to radioss?

Hi,

Try with Type 13 spring in Radioss. This beam type spring property works as a beam element with six independent modes of deformation. This spring accounts for non-linear stiffness, damping and different unloading. Deformation, force and energy-based failure criteria are available.

For more details and input parameters, please refer our help menu.

hi,

is it possible to use Type 8 spring to simulate the cbush element?

Hi,

Type 8 spring property works with six independent modes of deformation and it is a zero length spring. This spring accounts for non-linear stiffness, damping and different unloading. Deformation, force and energy based failure criteria are available.

Do you mean that both Type 8 and Type 13 can solve my problem?

Try with Type 13 spring element.
