Analysis of Automobile Crash Responses Using Wavelets

Seat cushions for high-performance aircraft are typically selected for their ability to meet stringent specifications. One of the major criteria is the safety performance during an ejection. To address the design goals of cushion and material selection, a computational modeling method was developed that accounts for component and subsystem testing, component and subsystem modeling, validation criteria and, finally, theoretical application. This method is then demonstrated on designing a seat cushion that has optimized safety properties for an ACESII ejection seat.
