Description

The artificial feather and the shuttlecock that are used for shuttlecock

Technical field

The utility model relates to a kind of artificial feather that is used for shuttlecock, and the utility model also relates to the shuttlecock of being made by this artificial feather.

Background technology

Adopt artificial material to replace natural goose duck feather to make the ideal that shuttlecock is industrial circle and badminton circle.Because the durable resistance of goose drake feather shuttlecock is too poor, causes the sportsman to change the shuttle again and again, and 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 common people by no means can be imagined.Industrial circle is carried out relevant research work and is surpassed 20 years, but up to the present, also the shuttlecock that replaces the goose drake feather to make without any a kind of artificial material reaches the level of high-quality goose drake feather shuttlecock on combination property.The combination property of existing plastic shuttlecock does not satisfy level good amateurish competitor's specification requirement slightly at all, is abandoned by professional athlete especially.Up to 2007, just begin to occur having the special-purpose artificial feather (or claiming artificial feather) of shuttlecock of practical value; To the end of the year 2009, the shuttlecock listing of adopting artificial feather to make is arranged.But the shuttlecock that the artificial feather of this employing is made still exists, and rotary speed is not enough, complex manufacturing or overweight problem, 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 that impacts experience based on high-quality comprises weight, ball speed, rotation, high clear flight track, the stability of dropping shot, chops the chop and roll, bat feel, batting sound, accuracy in placement exactness or the like.The artificial material shuttlecock be exactly will be on these factors as much as possible near the natural goose feather ball of high-quality.

Influence the shuttlecock combination property, have following seven big 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 big technical barriers: material closes, structure is closed and technology is closed.Any one of this seven big key element and three big technical barriers can not be up to standard, and shuttlecock just can not passive movement person be accepted, and also just is difficult to achieve success commercial.Therefore when a kind of shuttlecock new technology of examination is whether practical, carry out multifactorial evaluation from above-mentioned seven big key element three disasters passes.In other words: slight shuttlecock is actually a system engineering, has comprised a plurality of subsystems, and tight association between each subsystem 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 20 years from the span that retrieves, the overwhelming majority is the independent transformation at a certain subsystem, and mostly is based on theoretical imaginary design, without actual verification.So almost do not have practicality all or can't realize.Also this reason just, just go through 20 surplus year, 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.

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 big more to overweight susceptibility, because the moment maximum of this position; If the skirt section kicks the beam, center of gravity too moves down, and then bulb tenesmus also influences performance.

Shuttlecock is very responsive to the variation of weight, and its susceptibility reaches the 0.1 gram order of 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, near the reducing in then 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 (the A district among Fig. 1) and pen feather district (the B district among Fig. 1), 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 following 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 light more good more, 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 the skirt section manufacturing technology of ultralight, carry out counterweight again 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 influence whole ball performance, unless adopt 15 feather system balls greatly about 0.05 gram.Even if restrain and adopt 15 feather system balls, 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 flight the time is pivoted and not only can be stablized 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 real core 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 to being exactly the weight issue that solves accessory pinna district part on the artificial feather.We 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, influencing the shuttlecock flying quality also has one not noted by the people, trickle, but The key factor very: if the wind resistance jumping phenomenon---ball skirt support bar is too soft, then the shuttlecock skirt section drastic deformation can occur being impacted moment energetically, recover normal immediately again, in this process of one of 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 shuttlecock that can obviously realize shuttlecock are distinguishing---go out feel of the ball feel and can become strange, drop point can be inaccurate.

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

The plumage stalk of the artificial feather of practical application at present has two kinds, and a kind of is the extraordinary nylon system plumage stalk of industrialization; Another kind is the plumage stalk that employing fibre reinforced composites bar still under test is made, also can coat the plastic cement surrounding layer in case of necessity in its outside, be exactly the plumage stalk of so-called suitcase cored structure, on September 16th, 2009, disclosed 200810034704 patent specifications had detailed introduction to this plumage stalk.But above-mentioned two kinds of artificial feathers all have defective separately.

There is overweight problem in the plumage stalk that extraordinary nylon is made.The extraordinary nylon plumage of practical application at present obstructs single weight and has reached more than 0.12 gram, adds accessory pinna and has just surpassed 0.15 gram, so have to adopt 15 feather system balls (standard is 16).But reduce weight as pipe, then its intensity is not much of that again.Although adopt 15 feather system balls, thus the ball skirt section point still slightly excess weight---the ball skirt of this shuttlecock nearly weighs 1.10 grams---having influenced the flying quality of shuttlecock to a certain extent---greatly and mainly shows: (1) batting feel lays particular stress on; (2) the shuttlecock batting is later sluggish; Very easily roll when (3) dropping shot, can roll during perhaps with racket top bead.Above-mentioned just these defectives, although make the sportsman not be ready very much still to adopt that this shuttlecock---the combination property of this shuttlecock has surmounted existing whole ball skirt plastic shuttlecock far away, and, can reach more than 2 times of common goose duck feather ball its service life.

The plumage stalk that adopts the fiber-resin composite bar to make has overcome the contradiction of weight and intensity fully---and that is to say this plumage stalk very light in weight, intensity is fine simultaneously, obstructs well many than extraordinary nylon plumage on combination property.But because the restriction of technology, this plumage stalk also has its intrinsic shortcoming.Because the superpower fiber-resin composite bar of this ultralight can only adopt pultrude process to make, so can't make certain tapering---adopt grinding method can make a big little tapering shape, but can seriously reduce its intensity.Therefore, this bar just can not be done too slightly, and not so the accessory pinna district of feather will be overweight.In this case, can only carry out independent overstriking to the pen feather district of this artificial feather, technical foundation of the present utility model that Here it is---the plumage pole-footing portion at artificial feather is provided with an overstriking sleeve pipe in addition.

Can so, after being provided with the overstriking sleeve pipe, plumage stalk root can bring overweight problem? shuttlecock is to weight all too sensitivity after all.Through a large amount of trial-manufacture of samples and test, when adopting external diameter to be 0.7 fiber-resin composite bar between 1.0mm, just can adopt this mode to solve the overstriking problem, and can be not overweight.Such as, length is the carbon fibre reinforced composite bar of 7.5mm external diameter 0.8mm, single weight is about 0.06 gram, the overstriking casing wt is controlled in 0.03 gram, add accessory pinna, single feather weight can be controlled at below 0.12 gram, meets the weight standard of high-performance shuttlecock with feather fully.And every mechanical strength at this time all is good.

The technical solution of the utility model is also brought the benefit of two beyong contemplations simultaneously: the one, and the impact strength of plumage stalk root improves greatly, thereby makes the durable resistance of shuttlecock that further improvement arranged again; The 2nd, shuttlecock waist coil can be more firm, and when not having the overstriking sleeve pipe, if there is not suitable glue, the following road waist coil of shuttlecock glides easily, had this problem of overstriking sleeve pipe just not exist.

Examination is beaten and is shown, the shuttlecock performance of being made by this artificial feather is very excellent.
