(來(lái)源：[])Therefore, people set their sights on the polar regions. The rational development and utilization of resources in the polar oceans have gradually been put on the agenda. Polar scientific expedition has evolved, and icebreaker shows its important role, whose main task is to open up new routes, carry out rescue and polarmaterials transportation. To this end, improving the ability of the icebreaker and developing new ship e particularly(來(lái)源：[]) important. Based on a voyage ice covered waters icebreaker bow, to determine the interaction of icebreakers and ice conditions, an ice load model was used to calculate the designing ice load according to the energy balance principle. The main contents are as follows:1. Summarize and analyze the main research method of ice load, and use MSC.Patran / Dytran software to carry out numerical simulation of ice loads. Determine the fe(來(lái)源：[])asibility of such analytical methods by comparing the test consults through numerical simulation analysis of the process to icebreak. Draw general rules of ice loads through simulating and analyzing cases under different conditions.2. Based on the principle of "collision type" ice-breaking method and finite element simulation method, research the key tech
