船模运动六分量的非接触式测试系统

采用目前工程领域应用广泛的非接触式测试技术,对船模六自由度运动量的测量进行了探索。利用类似DPIV(PIV)技术原理,通过追踪光源在屏幕的位移量来反映船模的运动量,消除了直接在船模自身加载仪器对其运动的约束影响。结合实际测试的数据结果进行了比较,证明了该系统的可信性。

Non-contact Test System of Six-component for Model-ship Test

By the non-contact test technique widely used in the realm of ocean engineering and research,the motion displacement with six degrees of freeson is tested.On the basis of DPIV(PIV)principle,the motion of model ship is reflected from fracing the displacement of light source on the screen.Therefore,it may eliminate the bound to the motion of model-ship due to loading the instruments on the model-ship itself.The system is proved to be reliable through comparison with the measured data.
