ABSTRACT

To establish the bending stiffness of wire ropes in free and forced bending, rope geometry and internal friction has to be taken into account. The paper describes a calculation method based on stress measurements, which includes both these influences. Because of the influence of friction the lubrication will affect the stiffness. Further more the change from free to forced bending will be determined and fatigue test in free bending conditions will be discussed.
