【Abstract】 In view of the complex shape and complicated modeling of marine propeller,a 3 D modeling method of marine propeller based on coordinate transformation of CATIA platform was proposed. The transformation formula from the local coordinate of the blade section to the global coordinate was given. It can be used to complete data processing rapidly in Excel. By CATIA secondary development based on VB. net,the rapid inputting and batch importing of the blade surface value data were achieved,so as to setup the 3 D propeller model quickly. The results show that the method is flexible and efficient,and the 3 D propeller model can be obtained and optimized quickly according to different design parameters.更多还原
