Study on Finite Element Nonlinearity Calculation of Folding Rudder

Abstract:

This paper introduces material nonlinear finite element method and the establishment of finite element equation and realizes accurate modeling and calculation of folding rudder using material nonlinear finite element method. According to calculation and analysis, it is shown that the stress in contact part is relatively large due to stress concentration and material enters plastic deformation area. The influence of material nonlinearity on deformation calculation cannot be neglected. In this paper, deformation calculation results well coincide with experimental results.
