基于Geomagic、Proengineer的轿车外观钣金件造型设计

Study on Design of Automobile Outer Covering Parts Based on Geomagic and Proengineer

针对轿车外观钣金件正向设计周期长、工作量大、成本高等问题,提出了基于Geomagic、Proengineer逆向工程与正向设计相结合的方法,阐述了逆向工程概念、应用及关键技术,通过实例验证了该方法的合理性,为复杂曲面的造型设计提供借鉴。

The top-down design of sheet metal parts for automobile is difficult and with long cycle and high cost,so combined with reverse engineering and top-down design,the technology based on Geomagic and Proengineer is proposed.The concept of reverse engineering,application and key technology are also discussed,and a rationality of the process is confirmed by an example,which could provide the reference for designs of complex parts.
