Volume One is intended primarily for the analyst who is interested in the theoretical bases of the MVMA Two-Dimensional Crash Victim Simulation. This volume contains the detailed formulation of the equations of planar motion of a vehicle occupant in a crash environment. The features of the analytical model include: (1) an eight-mass, fourteen-degree-of-freedom representation of the human body; (2) an extensible multi-joint neck and a flexible shoulder joint; (3) simulation of biodynamic muscle contraction as a time-dependent phenomenon; (4) the modeling of contact between the victim and the vehicle by means of contact-sensing ellipses attached to the body and a real-line representation of the vehicle interior or exterior; (5) specification of material properties of vehicle and occupant in terms of general force-deformation relationships; (6) structural collapse resulting either from collision forces or occupant contact forces; (7) an airbag model which predicts forces on the occupant by solution of the equations of gas thermodynamics; (8) a four-degree-of-freedom energy-absorbing steering assembly; (9) a simple energy-absorbing belt restraint submodel with three independent straps and an advanced belt restraint submodel with up to seven straps, two slip points, and vehicle-sensitive or webbing-sensitive inertia reels; (10) tabular three-degree-of-freedom vehicle accelerations.
