Calculation and Analysis of Strength,Stiffness and Vibration of a Ship Truss Type Integrated Mast
In order to study the strength,stiffness and vibration performance of truss type integrated mast of a marine scientific comprehensive research ship,a simplified model of the mast structure and local hull structure has been established by using finite element software MSC PATRAN/NASTRAN.According to Calculation Method for Surface Ship Structure Design,the strength,stiffness and vibration of the mast are calculated and analyzed by finite element method.The results show that the static and dynamic performance of the mast meeting the requirements.The calculation and analysis of the truss type integrated mast and the simplified selection of its boundary conditions proposed have certain universal significance and can be used for reference by relevant designers.
