Impact or acceleration from an automobile crash, a helicopter hard landing, or a roadside explosion can cause serious or even fatal injuries to a human. Impact biomechanical modeling and simulation can be used to discover injury mechanisms, assess injury risks under various scenarios, and optimize energy-attenuating structures, restraint systems, and protection devices to mitigate injury risks.

Innovision researchers have nearly 30 years of R&D experience in impact biomechanical modeling and simulation. Projects we have worked on include: building a full-scale finite element crash model of a 1997 Honda Accord; limiting performance analysis of seat belts; modeling and simulation of out-of-position occupant-airbag interaction; optimal control of helicopter seat cushions for the reduction of spinal injuries; ejection seat simulation; and a mobile robotic helicopter seat with optimized energy attenuation (SBIR Phase I and II).
