How do you analyze crash pulse data to evaluate occupant protection?

Crash pulse analysis examines vehicle deceleration during impact: Peak deceleration affects maximum occupant loading; pulse duration influences total energy absorption; pulse shape (square vs triangular) affects peak force timing. Analysis includes filtering raw acceleration data per SAE standards, calculating velocity change (delta-V), evaluating timing relative to restraint deployment, and comparing against target corridors. The goal is a pulse that allows controlled energy absorption while maintaining survival space. Optimization involves balancing structure stiffness for energy absorption versus occupant compartment protection.
