Survivability Analysis for the Evaluation of Personnel in Body Armor

摘要

The U.S. Army performs combat system survivability/ lethality/vulnerability (SLV) analyses using a software package called MUVES-S2. MUVES-S2 is an Army developed and maintained SLV computer model capable of analyzing the effects of one or more munitions against aircraft or ground-mobile targets and personnel. A new approach to personnel survivability and casualty assessment has been developed by integrating the Operational Requirement-based Casualty Assessment (ORCA) modeling system into MUVES-S2. ORCA is the tri-service developed personnel model and provides improvement for all phases of the casualty assessment process including more precise anatomical representation, mapping of insult(s) to injury evaluation, mapping injury to medical casualty characterization, mapping injury to physical and cognitive impairment, mapping job and task requirements to basic human capabilities, evaluating basic human capability requirements to post-injury capabilities, and calculating operational casualty metrics. This paper presents an overview of the MUVES-S2/ORCA methodology, highlighting improved capabilities and new techniques for performing SLV analyses of personnel wearing various body armor configurations. We will show how body armor survivability studies incorporate the use of injury characterization to quantify the vulnerability of a protective system against an understood threat. The ability to model small changes in personal protective equipment and their effect on personnel survivability will also be demonstrated.
