General Spring
General Spring Type
Select general nodal spring stiffness to be entered from the previously defined general spring stiffness.(Refer to "Define General Spring Type")
Click to the right to display the General Spring Type dialog box.
SDx: Spring stiffness in GCS x-direction (or node's local x-direction when defined)
SDy: Spring stiffness in GCS y-direction (or node's local y-direction when defined)
SDz: Spring stiffness in GCS z-direction (or node's local z-direction when defined)
SRx: Rotational spring stiffness about GCS x-axis (or node's local x-axis when defined)
SRy: Rotational spring stiffness about GCS y-axis (or node's local y-axis when defined)
SRz: Rotational spring stiffness about GCS z-axis (or node's local z-axis when defined)
Note
The above 6 spring stiffness values represent only the 6 diagonal terms in the 6 x 6 stiffness matrix entered in General Spring Type
Mass: When the mass matrix is defined in Define General Spring Type, "Considered" is displayed. When there is no mass matrix defined, "None" is displayed.
Damping: When the damping matrix is defined in Define General Spring Type, "Considered" is displayed. When there is no damping matrix defined, "None" is displayed.
