EFFICIENT COMPUTATION OF HEAD INJURY CRITERION (HIC) VALUES

This report describes the methodology and the associated computer program for efficient computation of the maximum Head Injury Criterion (HIC) value of a resultant head acceleration time series. The method exploits the monotonicities within the HIC function to find the global maximum with a branch and bound scheme. The FORTRAN77 program which uses this method, HICOP, has been implemented in the NHTSA VAX 11/780 environment. HICOP is between 15 and 120 times faster (in CPU time) than previous exhaustive search methods. The modifications and FORTRAN code necessary to create both a generalized HICOP program for other environments and a reduced storage version suitable for microcomputer applications are supplied.
