| 摘 要： | 为了研究全垫升气垫船的操纵性,建立了气垫船的运动仿真模型.通过船模风洞试验和平面运动机构试验分别得到了气垫船的空气动力系数和水动力系数,建立了空气动力和水动力数学模型;对各个方向的合外力进行合成,依照牛顿动量和动量矩定理,建立了全垫升气垫船的运动数学模型.利用冻结一解冻算法编制了气垫船运动仿真程序,并进行了操纵仿真试验,研究了气垫船的直线航行与回转运动的操纵特性.仿真结果表明所建立气垫船模型是合理的,所采用的算法是有效的.

| Abstract: | A simulation model was set up to research the maneuverability of air cushion vehicle(ACV).The coefficients of aerodynamic force and hydrodynamic force were got through wind tunnel experiments and model experiments with Horizontal-Planar-Motion-Mechanism respectively.Outside forces of each degree of freedom were sum med up,and then a mathematic model of ACV's motion was established according to Newton's momentum and moment of momentum theorem.Simulation program was programmed using freeze-defreeze arithmetic... |
