A hull motion measurement method and a hull characteristic law detection system using the same are characterized in that first to fifth acceleration sensors are installed on a hull, the first, second and third acceleration sensors are located on the longitudinal section of the hull, the second acceleration sensor is located at the center of gravity of the hull, and the first and third acceleration sensors are located at the bow and the stern of the hull respectively; the fourth and fifth acceleration sensors are positioned on the same cross section of the hull and are symmetrical about the longitudinal section of the hull; connecting the first to fifth acceleration sensors with a signal acquisition system, and connecting the signal acquisition system with a processing system; when the ship body sails, the first to fifth acceleration sensors output acceleration signals in real time, the acceleration signals are collected by the signal collection system in real time, the processing system processes the acceleration signals to obtain heaving, pitching and rolling motions of the ship body, and synchronous collection of the ship body motion, wave load, pressure and the like is achieved through the same signal collection system. And a deeper research can be carried out on the characteristic rule of the internal corresponding relation of the hull parameters.
一种船体运动测量方法及运用其的船体特征规律检测系统,包括:在船体上安装第一到第五加速度传感器,第一、二、三加速度传感器位于船体中纵剖面上,第二加速度传感器位于船体重心,第一、三加速度传感器分别位于船体的船首和船尾,第四、五加速度传感器位于船体同一横剖面且关于船体中纵剖面对称;将第一到第五加速度传感器均与信号采集系统连接,信号采集系统与处理系统连接;船体航行时第一到第五加速度传感器实时输出加速度信号并由信号采集系统实时采集,处理系统处理加速度信号后获得船体的升沉、纵摇和横摇运动,实现船体运动与波浪载荷、压力等通过同一信号采集系统进行同步采集,可对船体参数内在对应关系的特征规律开展更加深入的研究。
