摘要: 基于多体系统动力学理论,定义并选取适当的坐标系和广义坐标,对波浪驱动水下航行器多体系统进行运动学分析,得到各部分的速度和加速度;基于Kane方法进行动力学分析,计算各部分的偏速度和偏角速度,进而求得系统的广义主动力和广义惯性力。将系统的广义惯性力和广义主动力代入Kane方程中,得到波浪驱动水下航行器多体系统动力学模型。在受力分析中,不仅考虑了惯性力、惯性力矩、重力和浮力以及流体动力,还重点分析了波浪力和多体系统的附加质量力。对波浪驱动水下航行器进行了运动仿真,仿真结果显示航行器航行稳定,所建立的模型是有效的。

Abstract: A coordinate system for wave-driven underwater vehicle is defined based on multi-body system dynamics theory. The kinematics analysis of the whole system is performed by choosing the appropriate generalized coordinates, while the velocities and acceleration are deduced, and the expressions of partial velocities and partial angular velocities are deduced based on Kane’s method according to the dynamic analysis of the whole system. The generalized inertial force and generalized active force of the whole system are calculated. A multi-body system dynamics model of wave-driven underwater vehicle is established by taking the calculated results into the Kane’s equations. The force analysis of the proposed model focuses on the wave force and the additional mass force of multi-body system besides inertia force, inertia moment, gravity, buoyancy and hydrodynamic forces. The wave-driven underwater vehicle is simulated. The simulated results show that the proposed modeling method is valid.
