Abstract:Crashworthiness of automotive vehicles and impact response of highway structures represent very active research areas. The ultimate goal is to design vehicles and highway structures to minimize risk to passengers while also controlling damage to vehicles and barriers. The main task of the current investigation is to develop Virtual Reality Visualization (VRV) as a tool for visualizing finite element (FEA) simulations of automobiles, trucks and barriers in crash scenarios. VRV integrated with FEA has great potential for drivers and personnel training. Finite Element Analysis has been in use for many years. Many codes are available for a variety of analyses such as static, dynamic, thermal and modal response. VRV allows more effective assimilation of the voluminous output files. The main intent for this system is training of a large number of personnel. The analyst or trainee can ?fly by? and/or ?fly through? the impacted structures as though 'immersed' in them. The finite element models used are adapted from public models available from NHTSA (NHTSA, 2000), based on LS-DYNA, a Finite Impact Element Code. VR libraries are built using the ASCII output files from the code. Those libraries are subsequently accessed by the user. Details of the archived models, such as element types and constitutive relations, are enhanced to accommodate a broad range of crash scenarios, including vehicles crashing into each other and higher impact speeds. The output files are used to create Crashworthiness Effect Files in Virtual Reality Multi Language (VRML) format for visualization. References, 10 figures, 15 p.
