摘　　要：根据锤击法测量结构动刚度的原理,进行了某舰尾轴架动刚度的测量,得到了前尾轴架横向动刚度曲线、后尾轴架横向和纵向动刚度曲线;分析动刚度曲线,得到了尾轴架的固有频率,此结果与用有限元法对尾轴架进行振动计算的结果比较接近.Based on the principle of measuring structure dynamic stiffness using hammer exciting, the dynamic stiffness of shaft brackets for a vessel is measured. The transverse dynamic stiffness curve of front shaft bracket, the transverse and longitudinal dynamic stiffness curve of back shaft bracket are obtained. The natural frequencies of shaft brackets are available through an analysis of the dynamic stiffness curves. They can also be calculated using finite element method. A comparative analysis indicates that the two results are similar.
