- Definitions:
nbstep -- Number of rotation velocity steps.
keyunit1 -- Key for the bearing characteristics units. If keyunit1 is not on file, it defaults to 1.
If keyunit1 = 0, there is no transformation. If keyunit1 = 1, it transforms lbf/in into N/m and lbf.s/in into N.s/m. keyunit2 -- Key for the rotational velocity unit. If keyunit2 is not on file, it defaults to 1.
If keyunit2 = 0, there is no transformation. If keyunit2 = 1, it transforms rpm into rd/s. id -- Step identification number.
omega -- Current step rotational velocity (see keyunit2 for units).
K11, K12,.. -- Stiffness characteristics at omega (see keyunit1 for units).
C11, C12,.. -- Damping characteristics at omega (see keyunit1 for units).
