摘要

In order to obtain the time history of wave load on slender vertical cylinder of offshore engineering platform, a method based on random wave theory is proposed. This method analyzes the action process of wave motion on slender vertical cylinder, linearizes the horizontal velocity of wave by using stochastic equivalent linearization method, and calculates the time history of wave load by target spectrum method. On this basis, through MATLAB software, combined with the calculation algorithm of wave load time history, the wave load calculation software is compiled, and the numerical simulation of wave load is completed. The simulation results show that the method can obtain the time history of wave load acting on the slender vertical cylinder of offshore engineering platform, which provides an effective method for the calculation of wave action on offshore engineering equipment.
