Impact or acceleration from an automobile crash, a helicopter harsh landing, or a road-side explosion to a human can cause serious or even fatal injuries.  Impact biomechanical modeling and simulation can be used to discover the injury mechanism, to assess injury risks under various scenarios, and to optimize energy attenuating structure, restraint systems, and protection devices to mitigate injury risks. Innovision researchers have nearly 30 years of R&D experience in the area of impact biomechanical modeling and simulation. The projects we have worked include building a full-scale finite element crash model of 1997 Honda Accord, limiting performance analysis of seat belt, modeling and simulation of out-of-position occupant-airbag interaction, optimal control of helicopter seat cushion for the reduction of spinal injuries, ejection seat simulation, and mobile robot helicopter seat with optimized energy attenuation ( SBIR Phase I and II).
