“…A készülék valamennyi alkatrészét C45 minőségű szerkezeti acélból gyártottuk, amelynek folyáshatára (R eH ) az előgyártmány méretei alapján 370 MPa. Vizsgálat során lineáris anyagmodellt használtunk, amihez 200 GPa értékű rugalmassági modulust és 0,3 értékű Poisson-tényezőt állítottunk be [6]. A legnagyobb szerkezeti feszültség σ red,max = 141, 16 MPa, amelyek alapján biztonsági tényezőt számoltunk:…”

Munkánk fő célja acélsodrony mechanikai tulajdonságainak vizsgálata. Ennek megvalósításához univerzális anyagvizsgáló géphez csatlakoztatható befogókészüléket terveztünk. Elsőként 3D modellező szoftver segítségével megterveztük a befogó készüléket, amit végeselem módszer segítségével szilárdságtanilag ellenőriztünk. Ez a készülék a kötélsúrlódás elvén működik és a kereskedelmi forgalomban kapható befogók tulajdonságait ötvözi. Ennek segítségével 4 mm névleges átmérőjű, korrózióálló acélsodronyokat vizsgáltunk. Ez alapján meghatároztuk a vezetékek szakítószilárdságát és közelítő anyagmodelljét.

“…Vennemann et al [37] investigate the loss of the metallic area (LMA) and local faults (LFs) by using magnetic non-destructive tester. Mouradi et al [38] examine the mechanical behaviour of steel wire rope and establish a criterion for replacement. The service/operational life of wire rope is approximated on the basis of the strength variation.…”

Optimal selection of wire rope for various industrial applications is a multidisciplinary procedure. In this paper, optimum selection of wire rope for winch trolley in hot rolling shop is comprehensively demonstrated using finite element analysis. Powerfoam wire rope can be operated at lower D/d ratio and have 2.5 times longer service life as compared to their stranded conventional counterpart. The parameter-based geometric models of commercially available multi-layer wire ropes of 1 + 6 + 6 strand construction are designed using modelling software, SolidWorks, and procedure is followed by finite element analysis on ANSYS. The service life of wire rope is a function of factor of safety. Finally, cost analysis is delivered for optimum selection of wire rope, as an economical insight of the study.

“…Some scholars have performed much research work on the mechanical properties of wire rope by means of experiments. Mouradi et al [ 13 ] monitored the damage evolution process of 19 × 7 non-rotating wire ropes through fracture tensile tests, and defined the different stages of damage evolution of the wire rope and the critical life fraction that may lead to sudden failure. In view of the negative influence of broken wires on the mechanical properties of wire ropes, Zhang et al [ 14 ] conducted bending fatigue tests on the wire rope samples with different pre-broken wire distributions based on a self-made bending fatigue test device and found that broken wires increased the stress in the internal strands and the contact force between steel wires, thus reducing the service life of wire ropes.…”

In view of the serious friction and wear on the surface of a hoisting wire rope caused by the failure of lubrication under severe hoisting conditions, a study on the tribological characteristics of lanthanum stearate modified lubricating oil (LSMLO) was carried out. First, lanthanum stearate was prepared by the saponification reaction, and its surface morphology, chemical structure, thermal stability, and dispersion stability in IRIS-550A lubricating oil (IRIS) for wire rope were analyzed. Then, the tribological properties of LSMLO were investigated through four-ball friction tests and sliding wear tests of wire ropes. The results show that stearic acid almost completely reacts to produce lanthanum stearate, which has good thermal stability and a disordered layered structure. With the help of oleic acid, the dispersion stability of lanthanum stearate in IRIS can be significantly improved. The four-ball friction tests show that the optimal addition amount of lanthanum stearate in IRIS is 0.2 wt.%, and the CoF and wear scar diameter are reduced by about 35% and 25% respectively when lubricated with LSMLO compared to that with IRIS. LSMLO can better reduce the wear of the wire rope under different sliding speeds and contact loads than IRIS, and it exhibits improved anti-friction and anti-wear properties under high speed and low load.
