Computational modeling continues to play an increasingly significant role in the design of more effective vehicle crash safety systems. Researchers now frequently exercise models formulated with sophisticated computer analyses to supplement empirically generated results and conduct extensive what-if exploratory studies for information formerly available solely from costly and time-consuming physical testing. Our research team is developing a modeling and analysis capability that features a scientific visualization toolkit called NYSCEDII CRS visualization module (NCVM). NCVM post-processes conventional crash simulation imagery, enabling modelers to visualize aspects of both the digital model and the sled-test simulation in an immersive visual environment. This paper describes NCVM’s design and development in detail and illustrates its application to a series of sled tests conducted with a recent-production child restraint system and dummy occupant.
