摘要: 为提高船舶救生模拟训练系统中自由降落式救生艇运动仿真的精度,首先分析了救生艇两种释放方式的运动过程,将救生艇自由降落过程分为下滑、旋转、自由下落、入水这4个阶段,并对每个阶段进行受力分析,建立运动方程。根据动量理论和切片理论计算救生艇入水时所受砰击力,利用插值计算方法对救生艇横截面半宽和其入水时的附加质量进行计算,利用Kane方程为吊放救生艇的过程建立运动学方程。最终将数学模型应用到船舶救生模拟训练系统中,该模型能够满足系统需求,提高了仿真的逼真度。

Abstract: In order to improve the simulation accuracy of free-fall lifeboat movement in marine rescue simulation training system, the movement process of two release modes of lifeboat was analyzed firstly. The process of lifeboat free-fall was divided into four stages, including glide, rotation, free-fall, water entry.The force analysis of each stage was carried out and the motion equation was established.According to momentum theory and slice theory, slamming force was calculated when the lifeboat entered the water. The half-width of cross-section and additional mass of the lifeboat when it entered water were calculated by interpolation method. The kinematics equation was established for the process of lifting the lifeboat by Kane equation.Finally, the mathematical model was applied to the ship rescue simulation training system,and the proposed model can meet the system requirements and improve the fidelity of simulation.

Key words: ship engineering, lifeboat, free-fall, hoisting boat, Kane equation
