摘　　要：针对全垫升气垫船兴波问题,本文通过简化气室,采用质量源法模拟风机供气,在计算流体力学软件平台上实现了气垫兴波模拟计算。模拟中质量源法能够形成稳定的气垫,兴波波形合理,对内水面波形积分得到兴波阻力,能够准确给出速度变化过程中2次阻力峰值,与相关实验和文献结果比较,吻合良好。此外运用该方法研究了浅水中气垫船的兴波阻力变化情况,其第2个阻力峰的位置位于临界速度处。研究表明:该方法简单稳定,是气垫船兴波及阻力计算的有效手段。To solve the wave-making problem associated with air-cushion vehicles,in this study,we numerically simulated the waves generated by air-cushion movement on a computational fluid dynamics software platform.To do so,we simplified the air chamber and used the mass source method to simulate the air supply.In the simulation,the air cushion generated by the mass source method is stable,and a reasonable wave pattern is obtained.The air cushion wave-making resistance can be obtained by integrating the pressure and waveform over the water surface under the air cushion.The two peaks generated by the wave-making resistance with speed variation are captured quickly and accurately,and show good agreement with relevant experimental results and references in the literature.This method is employed to study variations in the wave-making resistance of an air cushion in shallow water.The second resistance peak appears at the position of critical speed.The results show that this method is simple and reliable in simulating the wave making of an air cushion and is effective for calculating the wave-making resistance of air-cushion vehicles.
