A Method to Quantify Mitigation Characteristics of Shock Isolation Seats Before Installation in a High-Speed Planing Craft

摘要

This paper presents a new approach for quantifying the mitigation achieved by a passive marine shock isolation seat. A brief historical perspective is summarized to explain why common myths have evolved that has led to seats being integrated into craft only to find out during subsequent seakeeping trials that the seats provide little to no mitigation or that they actually amplify wave impact loads. Acceleration data is presented to demonstrate use of the new computational method and the lessons learned are explained in terms that support development of a standard for laboratory seat testing.
