Embodiment Construction

[0015] Implementations of the present disclosure provide systems, methods, and computer-readable storage media for estimating the current physical condition of a rope product in use through non-destructive evaluation of the rope product's axial stiffness values. The axial stiffness value may be determined in part by monitoring the tension applied to the rope product when a load is applied to the rope product. Typically, when tension is applied axially to a rope product, a stress is created in the rope product, as well as a tensile strain proportional to the stress.

[0016] When a rope product is subjected to this tensile strain, elongation occurs. Elongation refers to the behavior of a rope product in which the length of the rope product increases. In an embodiment, the cross-sectional area of ​​the rope product may also vary with the length of the rope product based on the Poisson's ratio associated with the rope product. The axial stiffness value may also be determined in...

Abstract

Describes a method for the non-destructive assessment of the current physical condition of rope products in use. The method includes acquiring sensor data related to the rope product while the rope product is handling a load in use. Sensor data includes any combination of rope product elongation data, applied load data, and diameter data. The method also includes determining an axial stiffness value associated with the rope product based on the sensor data, and estimating a state of health of the rope product based on the determined axial stiffness value, the estimated state of health being indicative of a current physical condition of the rope product.

Description

[0001] cross reference [0002] This application claims the benefit of U.S. Provisional Application No. 62 / 235,263, filed September 30, 2015, and U.S. Provisional Application No. 62 / 262,622, filed December 3, 2015. technical field [0003] The present disclosure relates generally, but not exclusively, to systems and methods for estimating the current physical condition of a rope product while it is in use by non-destructive evaluation. Background technique [0004] Synthetic rope and other rope products are used in many industries for a variety of applications. For example, the maritime industry may use rope products for mooring operations to anchor ships at docks, while the construction industry may use rope products for cranes to carry and transport heavy loads. In each of these various applications, a load is applied to the rope product, causing a force to be exerted on the rope product. How the rope product reacts to these forces depends on the tensile properties of th...
