The Flexible Foundation node is added automatically when you set
Foundation properties to
Flexible on the parent
Radial Roller Bearing node. In this node, you describe the flexibility of the foundation on which the bearing is mounted.
Enter the values of the translational and rotational stiffness ku and
kθ of the foundation. Select the
Translational-rotational coupling check box to also incorporate the effect of coupled stiffness between the translational and rotational motion of the foundation. If selected, enter the values of the coupling stiffnesses,
kuθ and
kθu.
If you want to perform a dynamic analysis, you can optionally also enter the values of the translational and rotational damping, cu and
cθ, of the foundation. Select the
Translational-rotational coupling check box to also incorporate the effect of coupled damping constants between the translational and angular velocity of the foundation. If selected, enter the values of the coupling damping constants
cuθ and
cθu.
This node is automatically added when Foundation Properties is
Flexible in the parent bearing node. It cannot be added or removed manually.
