摘要：Freak wave is a kind of instantaneous disastrous wave with large wave height, which has great destructive effect on the navigation of ships at sea. Based on the layered Boussinesq equation, a wave model for focusing simulation of freak wave is established, and the numerical generation of freak wave is realized. Through the calculation results, the evolution process and the non-linear characteristic parameters of the freak wave are analyzed and discussed. The following conclusions are drawn: The influence of different energy distribution modes on the simulation of the freak wave is analyzed. Focusing model of simulated freak wave based on layered Boussinesq equation can reproduce freak wave events on random wave field when energy input of freak wave train reaches 10%. The simulation efficiency is high, the influence on skewness is small, and the influence on kurtosis is large.
