Characterization of Stiffening and Damping Materials for Planing Boat ShockMitigation

摘要

The occupants of high-speed planing boats operating in heavy seas are subject torepeated shock loads that can injure or impair performance. Identification and evaluation of shock mitigation concepts requires development of a nonlinear, time-domain, wave-to-wave elastic planing boat/human dynamic simulation. Shock mitigation concepts include the use of various stiffening and damping materials in the cockpit or within the hull structure. This report summarizes a general method for characterizing stiffening and damping materials and devices for use in a time-domain planing boat simulation, and derives the equations for the stiffening characteristics of several materials and devices.
