A Comparison of Whole-Body Vibration and Shock Response Spectra Parameters for Quantifying Mitigation Characteristics of Marine Shock Isolation Seats

摘要

This paper presents an analysis of the applicability of the vibration dose value (VDV) as a performance measure in single-impact laboratory testing of shock isolation seats. Acceleration data for individual wave slam events recorded on a shock isolation seat in a high-speed craft is used to compare the efficacy of the candidate VDV performance measure with a shock response spectra (SRS) performance measure. SRS and VDV numerical methods are described, computational results are summarized, and conclusions are presented.
