Abstract

Abstract

In this work, in order to reduce hull structural damage caused by ice impact, a new type of square groove longitudinal anti-ice structure is used in the shoulder structure of a hull in ice belt. Using a falling weight impact test system, the structural dynamic responses of anti-ice and prototype stiffened plates under the same ice impact case were tested and the impacting processes were simulated by the MSC.Dytran software. The results show that under the same impact conditions, the impact force produced by the anti-ice structure is slightly higher than that by the prototype one, and the maximum depression depth is smaller than that of the prototype one. According to the structural damage degree of the hull shell plates and their protection function to the hull internal components and equipment, the new structure has a certain anti-ice effect compared with the prototype structure. The results of the present study can provide a reference for the design of the anti-ice structures of ice-going ships or icebreakers.
