| Abstract: | In order to reduce the period of structural model establishment,a rapid parametric modeling software is developed with PCL language on the fuselage structure modeling for large transport aircrafts.A method based on quadratic curve is used to describe theoretical shape of fuselage,through which the shape of the parts of fuselage can be quickly created within a few parameters.Examples show that the software can generate the aircraft fuselage structural model rapidly and automatically and the efficiency of mod... |
