船舶气囊下水过程中船体倾角变化的测试与研究

为研究船舶气囊下水过程船体横向和纵向倾角的变化过程，采用基于工控机的倾角测试系统。该系统由倾角传感器、RS-232串行总线及工控机等元件组成。通过对测试结果的分析计算，结论表明：该船舶在气囊下水过程中，最大纵向倾角发生在船舶艉落阶段，最大值为1．8。左右，下水过程平稳，没有明显的艏落现象发生，同时船舶下水过程横向摇摆幅度很小。

Measurement and research on ship pitch change during process of ship launching by gasbag

In order to study the change of the transverse pitch and longitudinal pitch of ship hull during the process of ship launching by gasbag, a pitch measure system is applied which consists of pitch sensor, RS-232 serial bus and IPC. A test has been carried out to investigate the pitch change during launching process, and the results have been analyzed to show that the maximum longitudinal pitch is about 1.8°, while there isnt any obvious head decline during bulk cargo launching and the amplitude of transverse swaying is very little.
