Nonlinear Random Vibration of Deep-Water-High-Pier Under Non-Gaussian Wave Action
摘要
Abstract
A random dynamic model is established for deep-water-high-pier under non-Gaussian wave action,the non-Gaussian random wave process is simulated using Poisson white noise excitation,and the motion equa-tion of the deep-water-high-pier is derived by D'Alembert principle and the Galerkin method.The radial basis function neural network method is used to solve the generalized FPK equation,obtaining the transient response probability density function of the system.The effects of different structural parameters on the response of the system are examined,and the theoretical solutions are verified by Monte Carlo simulation(MCS).The results show that the theoretical solutions agree well with the simulation results.The increase of immersion ratio and mass ratio will amplify the response of the high pier.Gaussian model tends to conservative structural designs.关键词
