基于微动测量原理的高速船艏部结构运动规律研究

Research on the movement law of boat structure of high-speed boat based on the principle of micro-motion measurement

文章针对复杂荷载作用下的海上高速船首部结构易产生影响结构安全的疲劳裂纹、变形等威胁,运用基于微动测量原理的实船动态位移测量技术,研究了海上高速船首部结构的运动规律。研究表明:船首空舱结构以局部运动为主,未呈现明显的整体运动趋势,不会产出较大的支反力;基于微动测量原理的动态位移测量技术可为船舶变形长期监测提供新思路。

In order to solve the problem of fatigue crack and deformation caused by structural safety, the bow structure of sea high speed craft under complex load is easy to be affected. The motion of ship Is bow structure is studied by using the dynamic displacement measurement technology based on the principle of micro - motion meas- urement. The results show that the bow tank structure is dominated by local motion and does not show obvious over- all motion, and does not produce large supporting force. The dynamic displacement measurement technology based on the principle of micro - motion can provide long - New ideas.
