The parametric modeling program of T-type podder propeller shafting is developed by using the secondary development function such as knowledge fusion in NX software.In the developed program,the relationship between hull performance index and part dimension is established with the help of design manual and empirical formula,which reduces the input of dimension parameters.After entering the specified input parameters,the program automatically generates a matched three-dimensional model of T-type podded propeller shafting,which lays a foundation for the complete parametric modeling of podded propeller in the future.
