Description

A kind of artificial feather and shuttlecock prepared therefrom

Technical field

The utility model relates to a kind of artificial feather and shuttlecock prepared therefrom.

Background technology

Adopt artificial material to replace natural goose duck feather to make the target that shuttlecock is industrial circle and badminton circle.Because the durable resistance of goose drake feather shuttlecock is too poor, cause the sportsman again and again to change the shuttle, the cost of playing ball is improved greatly; Goose drake feather shuttlecock production technology cost numerous and diverse, material itself is also higher simultaneously.But the technical difficulty that this material replacement is hidden by no means common people can be imagined.Industrial circle is carried out relevant research work and is surpassed 50 years, but up to the present, the shuttlecock that also replaces the goose drake feather to make without any a kind of artificial material reaches the level of high-quality goose drake feather shuttlecock in combination property.The combination property of existing plastic shuttlecock does not satisfy slightly good amateurish competitor's specification requirement of level at all, is abandoned by professional athlete especially.Until 2007, the shuttlecock emulation feather dedicated for badmintons (or claiming artificial feather) that just begins to occur having practical value; To the end of the year 2009, the shuttlecock listing of adopting artificial feather to make is arranged.But still there are the problems such as the feather head is overweight, accessory pinna is easy to crack in the shuttlecock that this employing artificial feather is made, does not still reach the level of high-quality goose feather ball fully.

Shuttlecock is that a finesse in football skills degree to the ball product requires very high product.The sportsman has turned out the very fine and smooth experience that impacts in long-term exercise and match.This natural goose feather ball experienced take high-quality of impacting comprises weight, ball speed, rotation, high clear flight track, the stability of dropping shot, the rolling of chopping the chop, the feel of batting, bat sound, accuracy in placement exactness etc. as the basis.The artificial material shuttlecock be exactly will be on these factors as much as possible near the natural goose feather ball of high-quality.

Affect the shuttlecock combination property, have following seven large key elements at least: weight, distribution of weight, position of centre of gravity, spheroid support strength, positive wind resistance (or claiming axial wind resistance), around axle wind resistance and anti-fight endurance.Correspondingly just produce three large technical barriers: material closes, structure is closed and technique is closed.Any one of this seven large key element and three large technical barriers can not be up to standard, and shuttlecock just can not passive movement person be accepted, and also just is difficult to commercially achieve success.Therefore when whether a kind of shuttlecock new technology of examination is practical, comprehensively pass judgment on from above-mentioned seven large key element three disasters passes.In other words: slight shuttlecock is actually a system engineering, has comprised a plurality of subsystems, and is closely related between the subsystems, influences each other, and the small adjustment of any one subsystem all can drive the change of total system combination property.Surpass the patent specification in 60 years from the span that retrieves, the overwhelming majority is the independent transformation for a certain subsystem.By the end of 2007, except goose duck feather ball and the defective plastic shuttlecock of performance, occur without any the novel badminton that has practical value on the market.

Wherein wt, distribution of weight and rotation are the most scabrous key elements in the manually change process of present ball material.The ball skirt section of existing plastic shuttlecock and artificial feather is point mostly overweight.The center of gravity of shuttlecock preferably drops near bulb and the spheroid connecting portion.If the skirt section is too heavy, move on the center of gravity, shuttlecock very easily rolls, and the closer to shuttlecock skirt section apical position, just larger to overweight susceptibility, because the moment of this position is maximum; If the skirt section kicks the beam, center of gravity too moves down, and then bulb tenesmus also affects performance.

Shuttlecock is very responsive to the variation of weight, and its susceptibility reaches 0.1 grams magnitude, that is to say at some key positions, as long as the weight of 0.1 gram changes the great change that will cause the shuttlecock overall performance.And for the monolithic feather, the susceptibility of weight has then been reached 0.01 gram, and that is to say that if every feather increases by 0.01 gram, then near the reducing in whole ball skirt section adds 0.15 gram, such weight changes the flying quality with the heavy damage shuttlecock.And feather can be further divided into two zones to the sensitizing range of weight: accessory pinna district and pen feather district, accessory pinna district have comprised the upper half (with accessory pinna body contact portion) of accessory pinna body and plumage stalk; The pen feather district is exactly the lower half of plumage stalk.The accessory pinna district requires the harshest zone to weight in the whole shuttlecock.On engineering, the weight in shuttlecock skirt section (generally being made of tens accessory pinnas) is more light better, because guaranteeing that the shuttlecock spheroid has that to do gentlyer under the prerequisite of enough support strengths be a high-leveled and difficult technical problem to product, and after having grasped ultralight skirt section manufacturing technology, carry out again counterweight and then be easy to solve.The weight that alleviates the accessory pinna district can be set about from accessory pinna body and plumage stalk the upper half respectively.Some artificial material shuttlecock is for loss of weight, just ball skirt pole (or plumage stalk) make very carefully, ball skirt (or accessory pinna) does very thinly.Weight is up to standard, but insufficient strength.General shuttlecock uses the single weight of standard goose duck feather between 0.09g～0.12g, and wherein the accessory pinna district if the accessory pinna district surpasses 0.07 gram, will affect whole ball performance, unless adopt 15 feather balls processed greatly about 0.05 gram.Even if restrain and adopt 15 feather balls processed, the weight in accessory pinna district can not surpass 0.075---whole ball skirt weight preferably is no more than 1.10 grams.

Whether shuttlecock can stablize rotation is very crucial.Being used for promoting shuttlecock around the axle wind resistance pivots.Shuttlecock when flight pivots not only can stablize its flight course, and can effectively consume the part kinetic energy that flies, and during by hard smash, certain decelerating effect is arranged at shuttlecock, makes its flying speed more meet the requirement of motion.

Sum up in the point that a bit: the true kernel of artificial material shuttlecock is exactly the weight issue in ball skirt section point, as long as the weight issue of ball skirt has solved, other problem is just known about the basis of determining.Specific on the artificial feather being exactly the weight issue that solves accessory pinna district part.Can say that under the prerequisite of proof strength, the loss of weight that each person of outstanding talent of accessory pinna part is restrained all is valuable.

In addition, affecting the shuttlecock flying quality also has one not noted by the people, trickle, but very crucial factor: if the wind resistance jumping phenomenon--ball skirt support bar is too soft, then the shuttlecock skirt section drastic deformation can occur being impacted energetically moment, recover again immediately normal, process one of this contracting, wind resistance produces acute variation, make the shuttlecock flying speed produce the moment sudden change, perhaps, the sportsman can not directly feel the variation of this speed, but flight and the standard badminton that can obviously realize shuttlecock are distinguishing---go out feel of the ball feel and can become strange, drop point can be inaccurate.

Thus, conditioning each other of the exploitation forever seven large key elements of artificial material shuttlecock, three large difficulties only considers that performance in a certain respect is not all right.

The artificial feather of having realized at present industrialization is to adopt extraordinary nylon to make the plumage stalk.Other engineering plastics also can be used for making the plumage stalk of this artificial feather substantially, obstruct for plumage that the modified plastics on basis or alloy plastic can be used for making this artificial feather such as following listed engineering plastics and take it: polymethyl methacrylate (PMMA), polystyrene (PS), polyimides (PA) series, unsaturated polyester (UP) (UP), epoxy resin (EP), acrylonitrile-butadiene-styrene (ABS) (ABS), enhanced polyethylene (PE), polyformaldehyde (POM), RPP (PP), Merlon (PC), polyphenylene oxide (PPO) and Noryl, polyimides (PI), polysulfones (PSU), polyphenylene sulfide (PPS), PETG (PET), polybutylene terephthalate (PBT) (PBT), polyamidoimide (PAI), polyether sulfone (PES), polyether-ether-ketone (PEEK), PEI (PEI), polysulfones (PSF), polyarylsulfone (PAS) (PAS), polyether-ketone (PEK), polyarylate (PAR), polybenzimidazoles (PBI) etc.PA, PS, ABS, PP etc. can make alloy plastic with above-mentioned various engineering plastics, and these alloy plastics also are the good material of making artificial feather plumage stalk.

But still there is overweight problem in the plumage that these engineering plastics are made stalk, the artificial material plumage of at present practical application obstructs single weight and has all reached more than 0.12 gram, add accessory pinna and just surpassed 0.15 gram, so often adopt 15 feather balls processed (standard is 16).If but reduced weight with the rugosity that reduces the plumage stalk, then its intensity would be not much of that again.
