Investigation of Wave Impact Duration in High-Speed Planing Craft in Rough Water.

摘要

This report summarizes the investigation of wave impact duration. Example data plots are presented that show that impact durations vary from 100 milliseconds to 450 milliseconds for craft that weigh from 14,000 pounds to 105,000 pounds and have deep-V hulls with deadrise from 18 degrees to 22 degrees. Simple theoretical calculations are presented to show why impact duration is critical to understanding the effects of impact loads on physical systems.
