Abstract This paper discusses a combination of techniques that lets stylists and designers experience believable 1:1 interactions with virtual prototypes using immersive environments. The intent is to replace physical prototypes with believable virtual prototypes and then use them as the basis for communicating design intent within formal or informal design reviews. Achieving a reasonable degree of “believability” and natural interaction within this context requires addressing a broad range of problems, including: perception of scale, varying frame-rates, non-intuitive interaction devices and process and data integration just to name a few. In addition to these challenges, designers and stylists want to examine multiple forms of product data including bitmaps, movies, text information and 3D data within a single visual context. This paper describes an approach for visualizing and interacting with various forms of product data within a fully immersed environment for the purposes of concept design (the phase of product design where the overall functionality and shape of the product is determined [Kraftcheck, 1997]).

Safety Design

In the concept design phase of new car development, the parametric simplified side impact model was established by implicit parametric technology. The design parameters of BIW were optimized based on simplified model, such as the shape of section and the thickness of parts. The side impact safety performance and lightweight requirements were set as restraints during optimizing. The case indicated that the intrusion and intrusive velocity of B-pillar were reduced more than 30% and the mass was reduced 5.6% by this method.

Parameter Values

The simulation of joint is pivotal for car body structural analysis in concept design phase. The detail simulation method was implemented by solving the detail joint model using non-decoupling method. The detail information was afforded about joint detail modeling and the process of non-decoupling. The process of solving the parameters of joint was also described with equations. By the solved parameter values, the joint concept was built with ball hinge elements and spring elements. At last, a comparison between concept model with detail joint simulation and detail model of car body shows that the detail simulation method in this paper is feasible and accurate.
