Non-dimensional formulae are usually used to express the measured hydrodynamic forces and moments in ship model test, so that various geometric parameters are involved in uncertainty analysis.

Ship model tests are carried out, and the experimental results are presented in this paper.

In order to investigate the navigable condition of Xiangjiaba Bridge and the implements of the optimal measurements,the simulation study on navigation indexes of Xiangjiaba Bridge is carried out by ship model test,to ensure all boats can transit dam safely.

The development of JGⅡ-V30 general software in Three Gorge pivot ship model experiment;

According to the typical standard ship type for the upper reaches of the Yangtze River offered by the Ministry of Communications,and by theoretical means and ship model experiment,this paper studies the hydraulic parameter of the pebble rapids on the upper reaches of the Yangtze River.

The ship model experiment on Chengbeizun Reach in Yangzi River shoal regulation is introduced, it shows both the scheme of 80 and 60 m channel width can be true of navigation by 1000t ship teams.

By full-scale experiment with DGPS in bridge area,taking into consideration of ship′s excursion model in real navigation environment, comparison of ship′s trajectory between nu.

At the end of paper,we show some results of full scale trial,(that) the prototype worked stably and had a moderate good effect on roll stabilizing.

It would be troubled in naval weapons flight test when the target-vessel floats away or changes its attitude.
