Sensitivity of Occupant Response Subject to Prescribed Corridors for Impact Testing

Sensitivity of Occupant Response Subject to Prescribed Corridors for Impact Testing

A technology to study the sensitivity of impact responses to prescribed test conditions is presented. Motor vehicle impacts are used to illustrate the principles of this sensitivity technology. Impact conditions are regulated by specifying either a corridor for the acceleration time history or other...
