Description
Technical field
The present invention relates to ships in technical field of ships more particularly to a kind of guarantee measurement experiment freely to equal floating method.
Background technique
In ship light weight center of gravity measurement experiment, needs ship to remain and freely equal floating state, due to harbour
Water velocity is very fast, and the ship of experiment must be solid in quayside, only keeps freely putting down within the of short duration time of measuring floating.
When harbour is measured experiment, it is the solid hawser in harbour that ship, which needs to lengthen, puts down ship holding freely floating,
But since harbour water flow is fast, drives experiment ship mobile, the hawser between ship and harbour can quickly tensed, makes ship not
It is able to maintain and freely equals floating state.Therefore, it needs ceaselessly to observe whether ship cable loosens in measurement experiment, to guarantee to survey
Surely the accuracy tested, but the state of eye-observation hawser is only leaned on, increase the difficulty of experiment.
