摘要
游艇的运动数学模型是开发游艇模拟器的核心技术之一。根据分离建模思想,建立了游艇的平面运动数学模型。利用平面运动装置通过船模试验测得模型艇的水动力系数,分别计算作用于船体、螺旋桨和舵上的水动力和力矩,利用四阶龙格库塔法对船舶运动方程进行求解得到船舶运动参数。利用Visual Studio 2010编写了游艇运动的仿真程序,并以三艘游艇为例,进行了游艇的操纵运动仿真。将仿真数据与船模试验数据进行了比对,结果表明所建立的游艇模型能够满足游艇模拟器的精度要求。
Mathematical model of yacht is one of the key technologies for the development of yacht simulator. According to the separate model of MMG（Maneuvering Model Group）, a planar motion model of yacht was established. The hydrodynamic coefficients were obtained through ship model test by using PMM（Planar Motion Device）. Hydrodynamic forces and moments acting on the hull and propeller and rudder were calculated respectively. Ship motion equations were solved by means of the fourth order Runge-Kutta method, and ship motion parameters were achieved. Simulated program was coded through Visual Studio 2013, and simulations of three yachts were done. Comparisons between simulated data and ship model test data show that the established model of yacht can meet the requirement of yacht simulator.
