Finite element analysis on the stress state of rope hoisting equipment based on the ABAQUS
This paper presents a simulation of the steel wire rope of a certain type hoisting equipment to explore the distributions of stress and deformation in the process of lifting heavy loads. The SolidWorks software was used to establish the 3D solid model of the 6*6+WS structure of stone cross strand wire rope for a certain lifting equipment. Then the solid model of steel wire rope was imported into the ABAQUS directly through the SolidWorks and ABAQUS interface plugin, the material properties were defined, the contact pairs were established, the model was meshed, and the constraints were applied to solve the finite element model. In the normal working range of the wire rope, axial tension of 5000 N was loaded to analyse the stress and deformation distributions. The results show that the stress of wire rope presents a space spiral distribution and the stress of the lateral steel wire of the rope strand is the largest of the steel wire rope, which will provide reference for the design and improvement of the steel wire rope.
Finite element analysis of hoisting rope and fretting wear evolution and fatigue life estimation of steel wires
Abstract This paper is concerned with the finite element analysis of hoisting rope and three-layered strand for the exploration of fretting fatigue parameters and stress distributions on the cross-section. Also, the Archard’s wear law based evolution of fretting wear depth of wires crossed at different angles and implications to fatigue life estimations of fretted wires were presented. The results show that different wires in the rope or strand and distinct material models in the analyses both induce different stress distributions and fretting fatigue parameters. The predicted fretting wear depths of wires show good agreement with experimental results.
Researches on Structural Factor Involvement in Oral Tribology
This study is focused on two ceramic materials, D.SING (Ivoclar) and VM13 (emphasis the VITA TN), frequently used in restorative dentistry practice and it comes to complete a full set of results obtained by the authors over several years of research on oral tribology with main influence on oral health. In this way there are involved more specific structural aspects of dental restorative ceramic materials quality as is shown in [1].
