摘要
An analytical method is proposed for determining wave impact "slamming" pressures on all types of ship hulls including advanced vehicles that may travel at speeds up to 100 knots and even higher speeds. The method is based on the Wagner wedge impact theory, the Chuang cone impact theory, and experiments performed at the David W. Taylor Naval Ship Research and Development Center. Determination of the impact pressure is based on the hypothesis that the impact velocity is equal to the relative velocity normal to the impact surface of the moving body and the wave surface. The proposed method has been verified by several model tests in waves and by actual ship trials of the catamaran USNS Hayes. Computer programs are included for the practical use of the method.
