摘　　要：为了降低海浪波动对无人船的影响,设计一种带有隔振系统的波浪自适应无人船,并对其减振性能进行分析。对隔振系统的主要参数,即相对阻尼系数和固有频率进行求解。将无人船简化为四自由度动力学模型,并根据牛顿第二定律求出模型的运动微分方程。以随机海浪理论得出3级海况下波高曲线作为输入信号,通过Matlab软件的Simulink模块搭建求解模型,对浮筒位移、工作平台的位移和横摇运动进行仿真计算,通过对比分析研究得到波浪自适应无人船具备良好的减振性能。To reduce the impact of wave fluctuations on unmanned boats,a wave-adaptive unmanned boat with a vibration isolation system is designed and its vibration reduction performance is analyzed.The main parameters of the vibration isolation system,namely the relative damping coefficient and the natural frequency,are solved.The unmanned boat is simplified into a four-degree-of-freedom dynamic model,and the motion differential equation of the model is derived according to Newton's second law.Taking the wave height curve under the third-level sea state obtained by the random wave theory as the input signal,the solution model is built and solved by using the Simulink module of Matlab software.The displacement of the floating cylinder,the displacement of the working platform and the rolling motion are simulated and calculated.By comparing and analyzing,it is found that the wave-adaptive unmanned boat has good vibration reduction performance.
