Description
Technical field
The invention belongs to Ship Steering Autopilot technical field, be specifically related to a kind ofly turn fin inhibiting device for micro-miniature stabilizer.
Background technology
Stabilizer belongs to ship stabilizer, and wherein, micro-miniature stabilizer refers to that fin area is less than non-retractable (being also fixed type) stabilizer of 1 sq m.Micro-miniature stabilizer cost is lower, but market demand is comparatively large, batch micro operations often.The product of batch micro operations is when carrying out seriation (being divided into different size), and usually, specification number Yue Shao Vietnamese side is convenient to manufacture.The Specification of stabilizer divides according to the size of single fin area often, small-sized stabilizer no more than 10 specifications usually of single fin area 0.1 sq m to 1.0 sq m.Owing to having requirement of strength to the fin wing and fin axle, the fin axle of micro-miniature stabilizer should not be too thin, and the fin wing also should not be too thin, so the stabilizer that area is little is especially not easy to Design and manufacture.Usually, single fin area of the micro-miniature stabilizer of minimum gauge also should not be less than 0.1 sq m.
When carrying out the design calculation of micro-miniature stabilizer, be first determine that subtracting of required stabilizer shakes power capacity according to the work sea situation of ship parameter and ship.Subtract the size of shaking power capacity and fin area and the maximum size turning fin angle is relevant, normally hypothesis one is maximum further again turns fin angle (such as 30 degree), then, subtract and shake power capacity with regard to only relevant with the size of single fin area, determine the specification of stabilizer used thus.In fact, hardly may be just in time consistent with the actual fin area of a certain specification product according to this workflow management fin area out, at this moment normally select a specification comparatively close and slightly bigger than normal.Some displacement is less than to the speedboat of 10 tons, sometimes, the reasonable single fin area calculated only has 1/2 even 1/3 of 0.1 sq m, at this moment, single fin area have to be selected to be the micro-miniature stabilizer of 0.1 this specification of sq m, and now maximum turns fin angle and wants corresponding Scaling to original 1/2 even 1/3.
When product design, a mechanical stop limiter is normally designed to the maximum restriction turning fin angle, rely on mechanical position limitation to be comparatively failure-free.Although control software design also has identical restriction to the maxim turning fin angle, control signal is relied on to realize spacing reliability relatively low.At present, consider based on General design and producing in serial form, the maximum fin angle that turns that mechanical stop limiter limits is all certain fixed value, and certain value normally between 25 degree to 35 degree, the maximum fin angle that turns is nonadjustable.
When reasonable single fin area is 0.1 sq m 1/2 even 1/3, and the stabilizer selected is when be single fin area being the micro-miniature stabilizer of 0.1 sq m, current mechanical stop limiter normally out-of-action (because its maximum limit value turning fin angle of micro-miniature stabilizer of minimum gauge is all identical).In like manner, when the stabilizer specification selected is slightly bigger than normal than the fair-sized calculated, current mechanical stop limiter does not have position-limiting action usually yet.When turning fin inhibiting device and being inoperative (above-mentioned two situations), or, when turning fin inhibiting device and losing efficacy (such as only dependence control signal is spacing), turning fin angle likely can in some moment excessive (being greater than the angle desired by control command), and the actual moment that the fin wing produces just likely exceeds shakes theory that power capacity converts out and subtract according to required subtracting and shake moment.Consequence has two aspects, and one is that fin stabilizer is worked overloadingly, and affects service life and the reliability of device, and two is banking likely make ship moment, affects the traveling comfort of occupant.
