PitchBearingStiction

https://bladednextgen.dnv.com/schema/0.4.1/Components/PitchSystem/Friction/PitchBearingStiction/PitchBearingStiction.json

The additional torque resisting the initial movement of the bearing.

• ConstantStiction: number (Nm)
• StictionTorquePerUnitFrictionTorque: number
• FrictionTorqueVsStictionTorque: array[object (FrictionTorqueVsStictionTorque)]

Properties

ConstantStiction: number (Nm), optional

The stiction is the additional friction when the bearing is stationary (static friction = kinetic friction + stiction).

default = 0

StictionTorquePerUnitFrictionTorque: number, optional

A fixed ratio between the kinetic friction of the bearing and the stiction opposing the initial motion.

FrictionTorqueVsStictionTorque: array[ object (FrictionTorqueVsStictionTorque) ], optional

A look-up table describing a non-linear relationship between the friction of the bearing and the corresponding stiction.
