This document summarizes the capabilities of seat evaluation simulations including frontal/rear impact, seatbelt anchorage tests, child restraint systems, head restraint strength, and other tests. The simulations use standardized procedures and load cases to evaluate compliance with standards. Comprehensive reports are generated identifying critical areas, displacement/stress outputs, and countermeasures. Correlation with physical test results is also provided.
