Accident Reconstruction

Accident reconstruction is a general term that describes the analysis of an accident to determine how it occurred. The basis for accident reconstruction is Newtonian Physics.  Newtonian Physics or Classical Mechanics is the mathematical relationship between force, mass, and acceleration. Newton’s Laws of Motion, Conservation of Momentum, Conservation of Energy, and Time-Distance formulas are some of the analytical tools that can be used to accurately predict changes in a body’s motion resulting from the external forces acting upon it.

Accident reconstruction includes motor vehicular accidents, boating accidents, aircraft accidents, ski-mobile accidents, train accidents, industrial accidents, and construction accidents. The most common accident investigation involves motor vehicle-vehicle, motor vehicle-pedestrian, and motor vehicle-bicycle accidents.

Northeast Consulting Engineers, Inc. gathers evidence from the incident site, vehicles, witness statements, and other information. Engineering principles, mathematics, and physics are then applied to develop an understanding of the accident. Vehicle impact speeds, vehicle speeds prior to braking, post collision speeds, and accident avoidance measures are often some of the factors that are determined by an engineering accident reconstruction analysis.

Permanent deformation of a structure or vehicle component can be useful in determining how an accident may have occurred. For example, Northeast Consulting Engineers, Inc. has used Autodesk® Simulation Multiphysics software to determine the impact speed of a bicycle based on the deformation of the front fork.
