Experimental investigation and finite element analysis of a four-layered spiral strand bent over a curved support

The subject of study was a thin-walled C-section made of carbon fiber reinforced polymer (CFRP). Column was subjected to eccentric compression in the established direction. In the computer simulation, the boundary conditions were assumed in the form of articulated support of the sections of the column. Particular studies included an analysis of the effects of eccentricity on the critical force value. The research was conducted using two independent research methods: numerical and experimental. Numerical simulations were done using the finite element method using the advanced system Abaqus ® . The high sensitivity of the critical force value corresponding to the local buckling of the channel section to the load eccentricity was demonstrated.

“…FEM model was validated in experimental tests [2,4,5,6,7,16,17,18]. The C-section profile used during the experimental tests and the discrete model is shown in Figure 2.…”

“…Part 1: General) [5]. Several authors [3,7,10,11], engaged in problems of steel rope stress, their damage in operation, in experimental and simulation verification for different types of ropes and lay types, prove that rope under stress requires special attention. The stress states resulting from different kinds of loading [3] are often not included in calculations according to standards [1].…”

This article describes a specific analysis and evaluation process of a foundry crane installed in a steel mill. The main task was to analyse the possibility of increasing the lifting speed of the crane in order to improve the efficiency of the production process. The condition of the steel supporting structure of the given foundry crane was assessed by means of the performed experimental measurements and calculations. The present article describes the special experimental/analytical methodology for the evaluation of the crane steel construction and lifting and travelling mechanisms. Furthermore, the required modifications of the individual crane construction parts are explained.

“…In this case the wire layers contact at lines. In strands with a large number of layers the combination of point and line contacts between wire layers is possible [7].…”

et al. 2017

The paper presents the results of a numerical analysis of the stress-strain state of a rope strand with linear contact under tension and torsion loading conditions. Calculations are carried out using the ANSYS software package. Different approaches to calculation of the stress-strain state of ropes are reviewed, and their advantages and deficiencies are considered. The analysis of the obtained results leads us to the conclusion that the proposed method can be used in engineering calculations.
