2012 HVE Forum White Papers Now Available

As part of the HVE Forum each year, users have the opportunity to present technical papers related to HVE case studies, innovative tips and techniques, or any application of HVE showcasing its capabilities, especially events with important 3-dimensional vehicle behavior.

The following publications from the HVE White Paper Session at the 2012 HVE Forum are now available for you to download directly from the Library section of the EDC website:

A Method for Creating Photograph Textured Planes and Camera Positions in HVE Simulations
Brad R. Shults - Ponderosa Associates

A method for creating photograph backgrounds in HVE is presented. This method is useful for comparing simulation results to accident photographs evidencing the scene. Through the use of survey equipment, photogrammetry software, and CAD software, a user may calculate the photograph plane and respective camera position in three-dimensional space of a particular photograph. A process for determining the three-dimensional camera position and photograph plane center is presented. A process for creating the photograph texture for HVE is presented. After presenting the above processes, an example crash from the 2011 ARC-CSI Crash Conference is presented. Additionally, a case study photograph background is presented. Finally, results are discussed and recommendations for future work are presented.

An Introduction to the Vehiclemetrics HVE Vehicle Database
Ron Jadischke and Joe McCarthy - Vehiclemetrics/McCarthy Engineering Inc.

Vehiclemetrics is compiling a new vehicle database for use in HVE to increase the number of vehicles for use in HVE drastically. The procedure currently used by EDC for building vehicle geometry, as well as various input mechanical parameters for the vehicles, has been published by Garvey (2000) and Day (1995) and is also presented annually at the HVE Forum. The goal of this paper is not to repeat a discussion of the various input parameters. Rather, it is to present not only an overview of the process that Vehiclemetrics uses to generate vehicle interior and exterior geometry but also a mechanical property dataset for use in HVE. We have highlighted areas where Vehiclemetrics’ method and EDC’s method differ. The intent of the Vehiclemetrics vehicle database is to supply modern vehicle mechanical datasets that are vehicle specific and, in turn, minimize the use of generic data. At this time, all vehicle parameters cannot be measured within budget constraints, and notes are made regarding planned areas of improvement and future research areas.

Using HVE to Simulate a Nine Vehicle Accident Involving a Heavy Truck
Eric Rossetter, Benjamin Ewers III, Bradford Coburn, Yomi Agunbiade - Principia Engineering, Inc.

Multi-vehicle high-speed accidents that have a high number of vehicle collisions and interaction with a fixed obstacle in the environment are ideally suited for simulation. This paper covers a nine-vehicle collision involving a heavy truck and eight passenger vehicles. We constructed a 3-D environment in AutoCAD based on survey data, along with custom vehicle geometries not available in the HVE database. The final simulation using HVE's EDSMAC4 algorithm matched the physical evidence remarkably well. In addition, HVE allowed us to compare various impact speeds to show why certain scenarios did not match the physical evidence. The resulting simulations were used successfully in trial.

SIMON/DyMESH Validation Preview (Oral Presentation Only)
Eric Deyerl, P.E. - Dial Engineering
Louis Cheng, Ph.D. - Applied BioMechanics

This presentation provides a summary of the development history of SIMON/DyMESH. Prior validation studies and their results are discussed and a preview of a planned future suite of validation studies of Version 3.0 of DyMESH is presented.
