摘要
基于冰载荷经验公式和五种典型计算工况,利用有限元法进行了冰载荷下螺旋桨的强度分析,并建立了一种冰/桨叶碰撞计算模型,对碰撞过程中接触力的变化及螺旋桨的动态响应进行了研究。计算结果可供螺旋桨结构设计时参考。
The propeller strength under the ice loads is analyzed by the finite element method based on empirical formulas of ice loads and five typical load cases. The study of the change of the contact force and the dynamic response of the propeller in the collision process by using an ice^blade collision calculation model is analyzed The results provide reference for the structural design of propeller.
