【摘要】 本文建立了侧壁式气垫船在无航速和垫升状态时,横浪作用下的升沉与横摇耦合运动的数学模型,对脉动气垫压力引起的水面变形及兴波阻尼作了简化处理,借用常规船的试验数据,采用切片理论,对侧壁的附连质量与阻尼系数进行了插入计算。用此数学模型对719钢质船模在较小风扇流量时横浪作用下的耦合运动作了数值计算,计算结果与试验数据较为吻合。更多还原

【Abstract】 Nonlinear equations for coupled roll and heave motions of SES onstatical air cushion in regular beam seas are derived.The water surfacedeflection and wave damping caused by fluctuations of cushion pressureare simplified.The added mass and damping coefficients for sidewalls canbe calculated by means of experimental results and strip methods forconventional vessels.Using this mathematical method numerical calculationsfor a steel SES model type 719 on the given test conditions were obtai-ned.It is found that the calculation results are close to those obtainedfrom model experiments.Serious consequence of SES on beam seas have been reported world-wide.The calculation method and computer programme for coupled hea-ve and roll motions of a SES with small cushion air flow in beam seasare presented in the paper,which constitute the theoretical basis for esta-blishing transverse stability criterion for SES.更多还原
