Stabilization and modelling of tensile properties of braided synthetic fibre rope for dynamic loading

Impact behavior of nylon kernmantle ropes for high-altitude fall protection

“…The UIAA international mountaineering organization 17 only meets the requirements for the protection of conditional mountaineering and rock climbing when the climbing rope meets the requirements of five falls in the number of falls, and there is no requirement for the rope itself to change during the fall of the rope. 18 Emri et al 19 proposed a new method based on a simple non-standard drop weight experiment and developed a method to predict the impact force, the viscoelastic-plastic deformation of the rope, the energy stored, recovered, and dissipated during rope handling and The method of changing rope stiffness within each loading cycle. Nikonov et al 13 evaluated the influence of humidity on rope performance based on the experimental method of Sry et al 20,21 developed an impact testing machine using a falling weight to apply five consecutive impact loads to a pre-tensioned rope to evaluate the stiffness corresponding to the first impact-rebound load portion of each drop and proposed an empirical equation to estimate the rope stiffness after any preload treatment.…”
