A Comparison of Shock Isolated Seat and Rigid Seat Acceleration Responses to Wave Impacts in a High-Speed Craft

Abstract

This report introduces three relative measures of shock mitigation performance useful for quantifying different shock response phenomena observed on side-by-side rigid and shock isolated seats during wave impacts in a high-speed craft. Numerous data plots for the different measures are used to explain why the severity on a shock isolation seat can be less severe than on a similar rigid seat even when seat bottom impacts and dynamic amplification occurs on the shock isolated seat.
