Abstract：In order to solve the problems of complex structures stiffness and stress calculations in the design and manufacture of ship carrier，the space thin-walled finite element modeling method was investigated to model the ship carrier. The deficiencies of inaccurate calculation which used of plate girder finite element method were improved.The model of Wujiang Shatuo ship carrier was established and do the meshing based on the pretreatment functions of hypermesh software，and do the solve and post-processing based on the ANSYS software.Under the working condition of maximum limit，both the deflection of the main stringer，beam and the stiffness of the key

structure has been checked. On the basis of the above result，the methods of deformation observation of ship carrier were designed.The study results indicate that，the space thin-walled finite element modeling method has a good guidance significance in the the design and manufacture of the ship carrier，also has important reference value for the design of same type ship carrier.
