摘　　要：舵装置及附属结构是船舶航行过程中操控和控制航向的主要装置。该系统在使用过程中,由于受高强度应力集中、长时间的疲劳损耗等原因经常会产生裂纹。同时,由于舵装置长时间处于高湿度海水环境中,材料腐蚀速度快,一旦裂纹产生,如果不能及时发现并修理,容易产生较大的安全事故。文章将围绕半悬挂舵及贝克舵常见裂纹产生的位置、原因及修理方法进行探讨。The rudder and subsidiary structure are the main devices to control and control the course of ship navigation.In the process of using the system,cracks often occur due to high strength stress concentration and long fatigue loss.At the same time,because the rudder device is in the high humidity seawater environment for a long time,the corrosion speed of the material is fast.Once the crack is produced,if the repair can not be found in time,it is easy to produce a large safety accident.The location,causes and repair methods of common cracks in semi-suspended rudder and Baker rudder are discussed.
