Finite Element Analysis of Ice-Cone Interaction
A numerical simulation model which describes the ice-cone interaction process is presented. The model is based on the field observation which was made on the prototype platform named JZ20-2 MUQ. The dynamic numerical simulations are performed by using the LS-DYNA program and the present model. The failure evolutionary processes are analyzed between ice and conical shaped structure according to the stress distributions in the ice sheet. The distributions of the ice energy and contact force during the ice-cone interaction are also presented. The numerical results indicate that the present model and the modeling method are validated and reliable in describing the dynamic processes of the ice-cone interactions. Furthermore, the results could also provide the references for the ice resistant design of conical structure.
