摘　　要：针对地震作用下承船厢结构受力问题,进行厢-水-船耦合动力响应研究。利用ANSYS软件建立承船厢系统有限元模型,采用修正Housner理论模拟水-船耦合体作用,对比分析承船厢处于底部、中部和顶部3种工况下的动力响应。结果表明:同一地震作用下,承船厢位置从底部至顶部变化,承船厢结构主纵梁中部位置的横河向、顺河向最大加速度、最大等效应力都随之增大;当承船厢位于顶部时,横河向、顺河向的最大位移分别为263.31、0.174mm,最大加速度分别为3371.97、1.47mm/s^2,最大等效应力为52.76MPa;在进行承船厢设计时,可将承船厢位于顶部的工况作为设计依据。For the bearing capacity of ship reception chamber under earthquake,we study the coupling dynamic response of chamber-water-ship.Based on the ANSYS software,we establish a finite element model of ship reception chamber by the modified Housner theory to simulate the coupling action between ship and water,compare and analyze the dynamic responses of the system under three conditions including ship reception chamber at the bottom,middle and top.The results show that under the same earthquake condition,when the position of the ship reception chamber changes from bottom to top,the maximum stress,lateral and longitudinal acceleration all increase accordingly.The maximum lateral and longitudinal displacement and acceleration at the top are 263.31 mm and 0.174 mm,3371.97 mm/s^2 and 1.47 mm/s^2 respectively,and the maximum equivalent stress is 52.76 MPa.In the design of ship reception chamber,the working condition of ship reception chamber at the top can be taken as the design basis.
