摘　　要：对全垫升气垫船在波浪上航行的运动响应进行了研究.通过考虑若干主要非线性因素的影响,包括风扇风道的非线性影响、围裙触水产生的水动力的非线性影响以及围裙触水导致的气体逸流中断的影响,建立了全升气垫船在波浪中运动的数学模型.然后利用适当的数值方法,在时域上对气垫船非线性运动微分方程进行了计算,得到了气垫船的运动响应,分析了围裙触水的影响.并将理论计算结果与试验进行了比较分析,验证了理论计算方法的合理性.The motion of the air cushion vehicle （ACV） in waves was studied. An exact and logical mathematical model was set up through the analysis of several main nonlinear factors, including the influence of fan, the hydrodynamics and the interruption of air flow caused by the immersion of skirt. Then, the motion response of ACV was derived in time-domain through the calculation of the nonlin- ear motion differential equations in proper numerical method. The rationality and the accuracy of the nonlinear theory results were demonstrated through the comparison with experimental test results.
