A Novel Approach for Modeling and Simulation of Helix Twisting Structure Based on Mass-Spring Model

Abstract

In order to improve the modeling efficiency and realize the deformation simulation of helix twisting structure, a computer-aided design system based on mass-spring model is developed. The geometry structure of helix twisting structure is presented and massspring model is applied in the deformation simulation. Moreover, the key technologies such as coordinate mapping, system render and system architecture are elaborated. Finally, a prototype system is developed with Visual C++ and OpenGL, and the proposed system is proved efficient through a comparison experiment.

Unveiling a new shear stress transfer mechanism in composites with helically wound hierarchical fibres

“…In the wire rope model by Elata et al [24], neither torsion nor bending were accounted for, but double-helix behaviour of the strand and inter-wire adjacent load effects were incorporated in the study. Argatov [25] computed the effect of Hertzian contact between the external wires and the core, and Wang et al [26] improved the model efficiency by computing the helix twisting structure of the wires by means of a mass spring model. An analytical description of the axial-torsional response of single-layer metallic strands providing a symmetric stiffness matrix, in accordance with the Betti-Maxwell reciprocity theorem, was presented by Foti and Martinelli [27], who introduced a relevant extension of the Argatov-based approaches.…”
