The low speed shaft bending definition.

• EffectiveShaftLength: number (m)
• HingePosition: number
• TorsionalStiffness: number (Nm/rad)
• TorsionalDamping: number (Nms/rad)
• BendingStiffness: number (N/m)
• BendingDamping: number (Ns/m)

Properties

EffectiveShaftLength: number (m)

The length of the low speed shaft to be considered for the bending model, beginning at the outside face of the main bearing.

HingePosition: number, optional

The fraction of the low speed shaft length (from the hub centre) where the hinge between the two massless rigid shafts are connected.

TorsionalStiffness: number (Nm/rad), optional

The shaft stiffness about the axis of rotation.

TorsionalDamping: number (Nms/rad), optional

The shaft damping about the axis of rotation.

BendingStiffness: number (N/m), optional

The shaft's bending stiffness about any axis perpendicular to the axis of rotation.

BendingDamping: number (Ns/m), optional

The shaft's bending damping about any axis perpendicular to the axis of rotation.
