Analytical Methods for Aircraft Seat Design and Evaluation
This SAE Aerospace Recommended Practice (ARP) defines a means of assessing the credibility of computer models of aircraft seating systems used to simulate dynamic impact conditions set forth in Title 14, Code of Federal Regulations (14 CFR) Parts 23.562, 25.562, 27.562, and 29.562. The ARP is applicable to lumped mass and detailed finite element seat models. This includes specifications and performance criteria for aviation specific virtual anthropomorphic test devices (v-ATDs). This document provides a recommended methodology to evaluate the degree of correlation between a seat model and dynamic impact tests. This ARP also provides best practices for testing and modeling designed to support the implementation of analytical models of aircraft seat systems. Supporting information within this document includes procedures for the quantitative comparison of test and simulation results, as well as test summaries for data generated to support the development of v-ATDs and a sample v-ATD calibration report.
The changes in this revision represent the latest agreement obtained by the SAE SEAT Committee to provide the most current information on the topic. This revision adds details on the ES-2re ATD, recommendations on how to document the certification approach, and an analysis checklist. Preexisting sections of the document have been revised to improve clarity and provide additional information or correct errors.
