Abstract:  In order to study the influence of structural parameters of aluminium cable steel reinforced (ACSR) on its mechanical property under tensile load, a parametric finite element model of ACSR was established based on the ANSYS parametric design language (APDL). First, the stress distribution of TACSR/AS-410/70 and the variation law of its layered stress and strain with tensile loads were simulated and studied. And then the finite element model of TACSR/AS-410/70 was verified by the tensile experiment. Furthermore, the parametric finite element model was used to simulate the mechanical response of cables with different lay ratio or aluminum-steel ratio. It can be concluded from the simulation results that as aluminum-steel ratio increases, maximum equivalent stress between different layers of the ACSR increases more slowly with the increase of load, the maximum stress of the strand is lower, and the stress distribution between strands is more even. However, as the lay ratio of ACSR is smaller, the strand is tighter and stress of strands in different layers is larger. The experimental results provide significant implications for the design of ACSR’s structure and the selection and optimization design of cable clamp.
