Procedures Used to Generate Input Data Sets for the Articulated Total Body Model from Anthropometric Data.

摘要

Protection of passengers from injury during vehicle and aircraft crashes and the protection of a crew from injury during aircraft ejection situations is one of the important design objectives of vehicle and aircraft design engineers. An increasingly important tool in evaluating the safety aspects of different designs is computer software simulation. Calspan Corporation has developed a particularly sophisticated class of these programs. The class includes the 3-D Crash Victim Simulator (CVS) Model, developed under DOT sponsorship (Fleck, et al, 1974), and the Articulated Total Body (ATB) Model, developed from the CVS Model under the sponsorship of the U.S. Air Force Aerospace Medical Research Laboratories (AMRL) specifically for application to aerospace-type problems (Fleck and Butler, 1975). These programs model the human (or laboratory animal) body as a multi-segment chained system. Currently 15 segments are defined: head, neck, upper arm (left and right), lower arm (left and right; includes the hand), upper torso (thoracic region), middle torso (viscera), lower torso (pelvic region), upper leg (left and right), lower leg (left and right), and foot (left and right). Figure 1 provides two views of a body on which standard body segment cut-planes have been marked. The actual body landmarks defining these cut-planes are described in Chandler, et al (1975).
