Measurement sensor, control platform and data collecting system, control platform are electrically connected with wire and servomotor, the motion
Measurement sensor includes the gyroscope for being used for the tachymeter and rolling angular displacement for measuring ship speed, and control platform is according to spoiler
Relational expression between preselected protruding length and hull angular displacement, the angular displacement data of gyroscope measurement are handled, obtain reality
When spoiler extension elongation, then control servomotor to move spoiler to the setting for meeting hull angular displacement through drive mechanism
Extension elongation.
The spoiler has two, is symmetrically mounted on ship stern transom plate edge.
The shape of the spoiler and protective cover is consistent with stern transom plate bottom shape.
The beneficial effects of the invention are as follows:It is this reduce ship rolling motion flow-disturbing system include spoiler, servomotor,
Drive mechanism and control system.Servomotor exists through power transmission shaft connecting eccentric wheel, eccentric wheel rotation through roller urges and spoiler
It is reciprocating in the presence of back-moving spring.Control system includes motion measuring sensor, control platform and data collecting system,
Control platform is according to the relational expression between spoiler preselected protruding length and hull angular displacement, to the angular displacement number of gyroscope measurement
According to being handled, real-time spoiler extension elongation is obtained, then controls servomotor to move spoiler to completely through drive mechanism
The preselected protruding length of sufficient hull angular displacement., can be simultaneously this system provides a kind of spoiler for reducing ship rolling motion
Drag reduction and rollstabilization are realized, and installation is simple and convenient, can significantly improve security and rapidity during ship's navigation, has good
Business and military use.

Embodiment
In order to better understand the purpose of the present invention, technical scheme, it is described in detail below in conjunction with accompanying drawing.
Fig. 1,2 show a kind of structural representation for the flow-disturbing system for reducing ship rolling motion.In figure, this reduction ship
The flow-disturbing system of oceangoing ship rolling motion include the 5, drive mechanisms of the servomotor of protective cover 7, one of spoiler 12, one and
One control system.Protective cover 7 is using installation drive mechanism and the groove structure of spoiler 12.Drive mechanism include eccentric wheel 8,
Push rod 9 and back-moving spring 10, push rod 9 are connected after upper reset spring 10 is covered through fixing bearing 11 with spoiler 12, servo electricity
Machine 5 through the connecting eccentric wheel 8 of power transmission shaft 6, eccentric wheel 8 rotate through roller 13 promote push rod 9 make in the presence of back-moving spring 10 it is past
Multiple motion.Control system includes motion measuring sensor 1, control platform 2 and the data collecting system 3 being electrically connected mutually,
Control platform 2 is electrically connected with wire 4 and servomotor 5.Motion measuring sensor 1 includes the survey for being used for measuring ship speed
Fast instrument and the gyroscope of rolling angular displacement, control platform 2 is according between the preselected protruding length of spoiler 12 and hull angular displacement
Relational expression, the angular displacement data of gyroscope measurement are handled, real-time spoiler extension elongation is obtained, then controls servo
Motor 5 moves spoiler 12 to the preselected protruding length for meeting hull angular displacement through drive mechanism(As shown in Figure 3).
Spoiler 12 has two, is symmetrically mounted on ship stern transom plate edge(As shown in Figure 4).Spoiler 12 and protective cover
7 shape is consistent with stern transom plate bottom shape.
Using above-mentioned technical scheme, motion measuring sensor, including gyroscope:For measuring the real-time angle position of ship
Move, including roll angle, angular velocity in roll and rolling angular acceleration;Tachymeter:The speed of a ship or plane of measurement ship in real time.
Data collecting system 3, it is connected by wire with sensor, for gathering and preserving the motion state of ship in real time.
Control platform 2, the data of sensor are handled.According to existing control strategy, to the real-time rolling of ship
Angle value, angular velocity in roll value and rolling angular acceleration values carry out scaling respectively, automatically switch under the different speed of a ship or plane each
Proportionality coefficient corresponding to amount of exercise, introduce control algolithm and obtain the extension elongation of spoiler in theory, be converted into magnitude of voltage,
Servomotor is driven, more preferable drag reduction and rollstabilization effect is brought in a manner of realizing the Optimal Control under the different speed of a ship or plane.
The drive device of running part is servomotor, is connected by power transmission shaft with eccentric wheel.Fixing bearing is fixed on guarantor
