文中主要就气垫压缩性对气垫船运动、气垫压力响应以及实艇耐波性预报的影响进行了研究。首先遵循绝热变化规律，给出艇体由气垫压缩性引起的气垫流量变化；然后通过考虑围裙浸水等非线性因素，结合计及气垫压缩性的流量连续性方程，建立完整的艇体非线性运动微分方程，并运用合理的数值计算方法，得到艇体的运动响应、气垫压力响应；最后通过与模型试验结果的比较，说明了压缩性在气垫船运动计算与实船预报中的重要性和必要性。%This paper mainly focus on the investigation of the inlfuence of cushion compressibility on the motion response of air cushion vehicle(ACV), cushion pressure response and prediction of its seakeeping performance. Firstly, it derives the change of cushion lfow caused by the cushion compressibility on the basis of the adiabatic assumption. Then, it sets up the intact nonlinear motion differential equations through the flow continuity equations involved with the cushion compressibility and other nonlinear effects such as skirt immersion. It also derives the motion responses of vehicle and the cushion pressure responses by the reasonable numerical calculation method. Finally, the comparison with model test results shows that compressibility is important and necessary in motion calculation and full-scale prediction.
