Inverse Analysis of Pre- and Post-Impact Dynamics for Vehicle Accident Reconstruction

摘要

In the dynamic analysis of the vehicular accident reconstruction, the vehicle motion is typically analyzed in three phases. These are pre-impact motion, impact motion, and post-impact motion, which are usually analyzed in reverse order to occurrence. Tire -ground forces are important during the pre- and post-impact motions, and less important during the impact. E present a vehicular dynamic model for pre- and post-impact as a rigid body which moves under the influence of tire-ground forces.
