摘要：汽車座椅骨架在整體構(gòu)型以及零件組成方面相似度很高，適合利用計算機輔助技術(shù)進(jìn)行變型設(shè)計。在對汽車座椅進(jìn)行模塊劃分后，利用CATIA二次開發(fā)的CAA技術(shù)設(shè)計了一款汽車座椅骨架快速變型設(shè)計軟件，并連接數(shù)據(jù)庫，通過人機交互的可視化界面完成座椅差異化零件的參數(shù)化建模。使用CAA的裝配API對參數(shù)化后的零件及其他配套零件完成座椅整體的自動裝配。該設(shè)計縮短了汽車座椅開發(fā)的準(zhǔn)備時間，提高了汽車座椅骨架的設(shè)計效率和設(shè)計質(zhì)量。

Abstract：There is a high degree of similarity between different automobile seat frames in overall configuration and parts. It is of great practical significance to make full use of computer-aided technology in variant design of automobile seat frames. By the secondary development technology of CATIA based on CAA ( Component Application Architecture ), a rapid variant design software for automobile seat frames is developed. The parametric modeling and integral assembly of the seat differentiated parts are implemented through the visual interface of man-machine interaction by using the assembly API of CAA. The preparation time of automobile seat frames development is shorten, and design quality and efficiency are improved.
Key words：CAA；CATIA；automobile seat frame；rapid variant design
