摘　　要：针对船舶上层建筑的多种复杂开口群结构形式，用Abaqus进行数值模拟，得到各工况开口区域的振动频率以及在抨击载荷与惯性力载荷作用下的最大von Mises应力和最大位移.给出开口位置、开口尺寸和开口排列方式等情况对结构强度与刚度的影响规律.结果表明，最大von Mises应力和最大位移均出现在过渡面与舷侧的顶部交际处，最大von Mises应力大小在70~90 MPa，最大位移约为5 mm.Abaqus is used to simulate many complex structural styles of opening group. Then the vibration frequency of opening area in different cases are obtained, as well as the maximum von Mises stress and the maximum displacement under slamming loads and inertial force. In addition, the influencing factors are considered, such as opening position, aperture size, and arrangement of openings. Then the effect on the structural strength and stiffness is discussed. It is concluded that von Mises stress and displacement turns to be the maximum at the connection between transition surface and top side plate. Besides, the maximum von Mises stress is between 70 and 90 MPa, and the maximum displacement is about 5 mm.
