Summary
The GM/PACE sponsored Brigham Young University – Virginia Tech global vehicle collaboration project has created the need for a robust, parametric style of modeling which allows for rapid and accurate modifications to all components of the vehicle. Using the parametric power of a CAD system such as NX, models can be created in a manner that will allow modifications of dimensions to fit a variety of configurations. In this global vehicle collaboration project, parametric modeling techniques are effectively illustrated within the chassis component. Along with maintaining interfaces with every major component of the vehicle, the chassis must also be capable of morphing to fit any of the four body styles designed by the Industrial Design students. For this reason, the chassis must not only be extremely flexible, but it must also contain a high level of detail. The chassis component in our vehicle assembly can be sized using parameters such as wheelbase and car length, and flex to any value within a reasonable window. Using the WAVE functionality, interface locations can be defined and maintained based on the components, such as the suspension and the brakes. Using techniques such as WAVE and Knowledge Fusion facilitate the replacement of parts and can support a variety of configurations, and assures that the vehicle will assemble seamlessly. This paper will present the complete vehicle assembly structure and demonstrate its effective use of parametric techniques.
