Phase 1. Development of an Urban Warfare Virtual Environment. Modeling andSimulation of Weapons Effects on Building Structural Integrity and Personnel for DIS Virtual Environments

摘要

This effort will incorporate real time simulation of weapons effects into aDlS/HLA compatible urban warfare virtual environment. The Phase I effort identified key problems and relevant approaches for Phase II. Moreover, fundamental modeling and simulation issues which extend beyond the current application were addressed; i.e., how to embed modeling of physical processes (which is necessary if the objects in a simulation are to interact in a non-scripted manner) in real time visual simulations. During Phase I, a precision MOUT scenario for clearing a building was developed. This scenario included interior and exterior construction details, weapons and ammunition, soldier tasks an engagement ranges. Ballistic experiments were conducted on selected weapon target combinations to identify interactive dynamics, and provide data for texture maps and analytical models. A subreal-time code describing external and terminal ballistics of small arms was developed and correlated with experimental data. A stochastic model was developed to describe distribution of glass fragments from an incident blast wave. An approach was developed to describe structural integrity in explosive weapon effects environments using parametric solutions from hydrocodes and handbook solutions. A sub-real-time methodology using the MRC John 0. phantom, which will be interfaced with the Phase II virtual environment, will be employed to describe weapon effects on personnel. Finally, a digital fly through model of the McKenna Town Hall was developed and various weapon effects were statically simulated.
