摘　　要：文章研究了由冲撞式破冰引起的船舯垂向弯矩的计算方法。确定了模拟冲撞式破冰过程的有限元建模准则,对有限元软件进行了二次开发,采用多重失效面方式定义冰层的破坏模式。开发了FORTRAN程序,提取环境外载荷,计算由冲撞式破冰引起的船舯垂向弯矩,为预报船冰碰撞载荷提供了一种新的方法。A finite element method is introduced to calculate vertical moment in amidships caused by crash-breaking way. The principle of finite element model is discussed. And ice failure mode is based on multi-surface criterion. The crash-icebreaking way is simulated through the secondary development technology of finite element software. The FORTRAN program is developed to calculate the vertical moment in amidships, which provides a new method to predict ship and ice collision load.
