Parametric Modeling Based on KBE of CATIA

摘要

In the phase of multidisciplinary design optimization of UAV, according to the changes of the design parameters, structure scheme and the shape of the air-frame need to be continuously adjusted. The parametric modeling can avoid the disadvantages of 3D modeling, such as long time consuming, low efficient, and poor interaction, and it will be the important method of UAV of multidisciplinary design optimization. A 3D model of a UAV airframe by using the parametric modeling in CATIA software was constructed, which was the base of design and analysis of UAV.
