Description
Technical Field
The invention belongs to the technical field of ship tests, and particularly relates to a method for selecting a moving weight and a weight moving distance of a ship inclination test.
Background
In general, after a first ship is built, the weight and the gravity center of an empty ship need to be measured, so that the weight, the gravity center position and the initial stability state of the empty ship of the first ship are obtained, and the completion stability and the actual loading capacity of the newly designed ship are verified. And (4) calculating according to the initial stability in the ship industry standard according to a formula (1).
GM＝W*Y/(△*tgθ) (1)
In the formula:
GM-the value of the height of the initial stability in the test state, in meters (m);
w is the number of weights moved in the test, in tons (t);
y is the value of the distance traveled by the weight in meters (m);
delta is the value of the displacement of the vessel in the test state in tons (t);
theta-the experimentally measured value of the roll angle in degrees (°).
In general, ". DELTA" in the above formula can be directly obtained by searching the water displacement curve according to the draft of the ship on site, but the test moving weight (W), the weight moving distance (Y) and the transverse inclination angle (theta) are required to be selected according to the requirements of the inclination test standard, such as the requirement of 5.11 in the CB/T3035-2005 standard, and the moving weight used in the test is enough to generate the transverse inclination angle of 2-4 degrees on each side of the ship. When it is difficult to meet the requirement, depending on the type of ship or conditions, the minimum transverse inclination angle of each side should be not less than 1 °.
Obtained by transforming the above formula (1):
tgθ＝W*Y/(△*GMmeter) (2)
In the formula: GM (GM)MeterThe stability height obtained for the preliminary stability calculation book is given the same other symbols as in equation (1).
And then obtaining a transverse inclination angle theta through an arctangent function of a formula (2), wherein the moving weight (W) and the weight moving distance (Y) are two unknown numbers, values are converted for many times during actual selection, and the calculation result is judged through the formula (2) and the arctangent function until the transverse inclination angle calculation result meets the requirement that each side of the ship generates a transverse inclination angle of 2-4 degrees in the standard, or the minimum transverse inclination angle of each side is not less than 1 degree with difficulty.
