Description

Shuttlecock artificial feather dedicated and the shuttlecock of being made by it

Technical field

The present invention relates to shuttlecock artificial feather dedicated, the invention still further relates to the shuttlecock that adopts this artificial feather to make.

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, cause sportsman again and again to change the shuttle, and the cost that makes to play ball improve greatly; Goose drake feather shuttlecock production technology cost numerous and diverse, material itself is also higher simultaneously.But, this material replace hiding technical difficulty by no means common people can imagine.Industrial circle is carried out relevant research work and is surpassed 50 years, but up to the present, the shuttlecock that also replaces 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 can not meet slightly good amateurish competitor's specification requirement of level at all, is abandoned especially by professional athlete.Until 2007, just start to occur having the shuttlecock artificial feather dedicated (or claiming artificial feather) of practical value; At the beginning of 2010, just there is the shuttlecock listing that adopts artificial feather to make.But the shuttlecock that this employing artificial feather is made still exists the problems such as feather head is overweight, accessory pinna is easy to crack, still do not reach the level of high-quality goose feather ball completely.

Shuttlecock is that a finesse in football skills degree to ball product requires very high product.Sportsman, in long-term exercise and match, has turned out the very fine and smooth experience that impacts.This impacting experiences that to take the natural goose feather ball of high-quality be basis, 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.Artificial material shuttlecock be exactly will be in these factors as much as possible approach the natural goose feather ball of high-quality.

Affect 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 is also just difficult to commercially obtain successfully.Therefore when whether a kind of shuttlecock new technology of examination is practical, closes and comprehensively pass judgment on from above-mentioned seven large key element three disasters.In other words: slight shuttlecock is actually a system engineering, has comprised a plurality of subsystems, closely associated between subsystems, influence each other, the small adjustment of any one subsystem all can drive the change of total system combination property.From the span retrieving, surpass the patent specification of 20 years, the overwhelming majority is the independent transformation for a certain subsystem, and is mostly based on the imaginary design of theory, without actual verification.So almost all do not there is practicality or cannot realize.Also this reason just, just goes through more than 20 years, by the end of 2007, except goose duck feather ball and the defective plastic shuttlecock of performance, without any the novel badminton having practical value, occurs.

Contradiction between wherein wt, distribution of weight and plumage bar intensity is the most scabrous key element in manually change process of current 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 spheroid connecting portion.If skirt section is too heavy, in center of gravity, move, 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 skirt section kicks the beam, center of gravity too moves down, and 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 shuttlecock overall performance.And for monolithic feather, the susceptibility of weight has been reached to 0.01 gram, that is to say, if every feather increases by 0.01 gram, near the reducing in whole ball skirt section adds 0.15 gram, such weight changes the flying quality of heavy damage shuttlecock.And feather can be further divided into two regions to the sensitizing range of weight: accessory pinna district and pen feather district, accessory pinna district has comprised the upper half (with accessory pinna body contact portion) of accessory pinna body and plumage stalk; Pen feather district is exactly the lower half of plumage stalk.Accessory pinna district requires the harshest region to weight in whole shuttlecock.From engineering, the weight in shuttlecock skirt section (generally consisting of tens accessory pinnas) is more gently better, because product is done to such an extent that be gentlier a high-leveled and difficult technical problem under the prerequisite of enough support strengths guaranteeing that shuttlecock spheroid has, and grasped after ultralight skirt section manufacturing technology, then carry out counterweight and be easy to solve.The weight that alleviates 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 is by the single weight of standard goose duck feather between 0.09g～0.12g, and wherein accessory pinna district, greatly about 0.05 gram, if accessory pinna district surpasses 0.07 gram, will affect whole ball performance, unless adopted 15 feather balls processed.Even and if adopt the weight in 15 feather Zhi Qiu， accessory pinna districts can not be over 0.075 gram---whole ball skirt weight is preferably no more than 1.10 grams.

Whether shuttlecock can stablize rotation is very crucial.Around axle wind resistance, being used for promoting shuttlecock pivots.Shuttlecock when flight pivots not only can stablize its flight course, and can effectively consume the part kinetic energy that flies, and at shuttlecock, during by hard smash, has certain decelerating effect, 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 conciliation of the contradiction problem between shuttlecock spheroid support strength and the cloth of whole ball weight and weight.As long as this contradiction has solved, other problem is just known about basis certainly.Specific to being exactly to solve the intensity of plumage stalk and accessory pinna and weight and weight to want the contradiction between cloth on artificial feather.Can say, under the prerequisite of proof strength, be all valuable to each loss of weight of bold and unconstrained gram of artificial feather.

In addition, affecting shuttlecock flying quality also has one by people, not noted, trickle, but very crucial factor: if wind resistance jumping phenomenon---ball skirt support bar is too soft, shuttlecock skirt section there will be drastic deformation being impacted energetically moment, recover again immediately normal, process one of this contracting, wind resistance produces acute variation, make shuttlecock flying speed produce moment sudden change, perhaps, 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 large key element of exploitation forever seven of artificial material shuttlecock, three large difficulties, only considers that performance is in a certain respect not all right.

The artificial feather of having realized at present industrialization is to adopt extraordinary nylon plumage stalk processed.But still there is overweight problem in the plumage that this extraordinary nylon is made stalk.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 balls processed (standard is 16).If but reduced weight, its intensity would be not much of that again.Although adopt 15 feather balls processed, thus ball skirt section point still slightly excess weight---the ball skirt of this shuttlecock nearly weighs greatly 1.10 grams, and---having affected to a certain extent the flying quality of shuttlecock---is mainly manifested in: (1) batting feel lays particular stress on; (2) shuttlecock batting is later sluggish; (3) while dropping shot, very easily roll, or can roll during with racket top bead.Above-mentioned these defects just, although make sportsman not be ready to adopt that this shuttlecock---the combination property of this shuttlecock has surmounted existing Integral ball skirt plastic shuttlecock far away very much.In addition, because nylon material has higher water imbibition, generally reach more than 2%.And very serious to the intensity effect of plumage stalk after water suction, even can cause intensity to drop to the degree of using nothing but.Also have, nylon material is expensive, makes the overall cost of shuttlecock higher.

For the problem of above existence, we adopt take PC or PC/ABS alloy material and makes plumage stalk as basic modified plastics, has obtained good effect.Its advantage is mainly manifested in: 1, intensity is good, weight is low, can realize 16 feather balls processed of standard; 2, water absorption rate is extremely low, and generally below 0.7%, the impact on intensity after water suction is minimum; 3, low price, reduces the integrated cost of shuttlecock greatly.

Summary of the invention:

One of the problem to be solved in the present invention is to provide a kind of shuttlecock artificial feather dedicated, and another technical problem that the present invention will solve is to provide the shuttlecock of being made by above-mentioned artificial feather.

For solving the problems of the technologies described above, shuttlecock artificial feather dedicated of the present invention comprises accessory pinna and plumage stalk, it is characterized in that, it is that base-material is made that described plumage stalk adopts PC plastics or PC/ABS alloy plastic.

For the intensity of plumage stalk is further improved, can adopt the mode of adding glass fibre or carbon fiber to strengthen.

Adopt above-mentioned shuttlecock artificial feather dedicated just can make all good shuttlecocks of stability and durable resistance.

Compared to existing technology, the shuttlecock of being made by artificial feather of the present invention, has following advantage: 1, the good weight of intensity is low, can realize 16 feather balls processed of standard; 2, water absorption rate is extremely low, and generally below 0.7%, the impact on intensity after water suction is minimum; 3, low price, reduces the integrated cost of shuttlecock greatly.
