Implementing a vibration framework for simulation of VIV on rigid pier by SPH

Abstract

The purpose of this study was to find, with the aid of ANSYS software, a formula for a vibration design of bridge piers that provides maximum convergence with experimental results, the effect of waves on fixed and floating platforms is an important consideration for designing of offshore structures, and thus several experimental and numerical models have recently been presented. In this paper, a numerical model was developed in an ANSYS program to simulate current wave interaction with a vertical cylinder acting as a platform leg. This involved using smooth-particle hydrodynamics method (SPH) for solving the hydrodynamics, as well as using the finite element method with regard to the structural aspect, according to an experimental sample. The required data were gathered through a library method called SPH, which is a Lagrangianun meshed method and is sufficiently accurate for free surface modeling in comparison with other Eulerian mesh-based methods. In this connection, the capacity of the method to calculate in-line and cross-flow forces on a cylinder was considered using different time solution algorithms. The results showed that the predictor-corrector algorithm led to the most accurate finding, compared to the Beeman, symplectic, and Verlet algorithms. Although vibration of cylinder have been investigated. © 2006-2017 Asian Research Publishing Network (ARPN).
