Modelling of a Laser yacht mast

Abstract

The purpose of this work to investigate the deflection of a Laser yacht mast caused by trimming forces (in plane deflection) occurring within the Laser yacht rig and create a model that reflects this. Finite element analysis software is used for the creation and analysis of the model based on structural mechanics principles. Verification of the model is carried out through comparison with experimental results, where deflection is determined in different wind conditions, and improvements of the model are based on the disparity of the model and the experimental results.
