橫波繞射
英文
shear wave diffractions-
This method applies the extended strip theory to establish the nonlinear ship motion equations in regular head seas, obtains stable time course by resolving in time domain, and then pressure vectors will be available. the pressure includes static pressure, incident waves pressure, diffraction pressure, radiation pressure, and wave impact pressure, and changed with instantaneous draft of each intersection
該方法應用擴展的切片理論建立迎浪規則波中船舶非線性運動方程，通過時域步進求解獲得船舶剛體運動的穩定時歷，進而給出與船體各橫剖面瞬時吃水相對應的靜水壓力變化、入射波壓力、繞射壓力、輻射壓力和波浪沖擊壓力諸分量。After solution of radiational and diffractional fluid field of asymmetrical sections by applying the multipole expansion method, wave loads on damaged ships are calculated by the linear strip theory under the non - upright floating condition, taking the effect on the heel angle and trimming angle caused by the damaged tank inundation below waterline into account
然後採用線性切片理論，計及水線以下破損后船舶由於艙室進水產生的橫傾角與縱傾角的影響，利用多級展開法求解非對稱剖面的二維輻射和繞射流場，計算了破損船體非正浮狀態條件下的波浪載荷。The dissertation focuses on seismic wavefield forward modeling and migration for the fractured reservoir. the paper integrates and researches the wavefield extrapolation operator for lateral variation of velocity, analysis of the wavefield characteristic, forward modeling and depth migration of prestack and poststack seismic wavefield, creation of wavelet, design of the model with fracture and cavity, and computation of reflectivity
