A Measurement System of Ship Motions during ModelTests and Full Scale Seakeeping Trials

开发了一套耐波性船模和实船试验中测量船舶运动的系统 ,该系统由加速度传感器、角速率陀螺和数据分析、处理软件组成。在数据处理过程中 ,采用一种非线性迭代算法。对该测量系统进行了水池模型试验和实船试验的验证 ,也利用三自由度运动平台进行了比测 ,比较结果令人满意。本装置是一种可靠性好、成本较低的船模和实船在波浪中运动测量系统。

A measurement system has been developed for recording ship motions during model tests and seakeeping trials. The system consists of accelerometers, angular rate sensors as well as a PC with datalogging and analysis software.A non-linear iterative approach is used for the data processing.Model tests at a wave basin and full scale ship trials were conducted to verify the system. The comparison of the ship motions measured by the system with that by other systems is satisfactory. The present method provides a reliable and inexpensive alternative to other systems, e.g. gyro-stabilized platform or optical tracking devices.
