Neuartige Methode für die Abschätzung der Lebensdauer laufender hochmodularer Faserseile

Abstract

Manufacturer and users of lifting applications have today the aim to introduce high-modulus fibre ropes because of the high lifetime. For this it is necessary to know the lifetime of the ropes when bended over sheaves. Like with wire ropes, bending tests can be done that reflect the actual situation in specific rope drives. The above mentioned high lifetime of running fibre ropes leads to long running bending tests. Also it is not applicable to do bending tests for every possible combination of parameters that can be found. Therefore a method is needed to estimate the lifetime of a running fibre rope with a minimum of work. The paper will introduce the results of an investigation regarding an above mentioned method to estimate the lifetime of a running fibre rope. The investigations include the analysis which set of parameters have to be used, how far the estimations can be used and with which accuracy.
