Abstract
The invention relates to a method and a device for checking a trajectory and a flying distance of badminton in a badminton sport. The checking method is characterized in that the badminton which is taken as a checked body is arranged in the upper part of a wind tunnel and led to float by meeting an air layer which flows from a vertical lower side; thereby the floating state is checked. The checking device includes a badminton checking part, a layer flow generating part, a fan motor part and a wind speed control part. The invention can simply and conveniently carry out checking and judging on the characteristic of the badminton under the situation of not knocking out the badminton in fact.
Description
The present invention relates to the trajectory of badminton mesoptile ball and the inspection method and the device thereof of flying distance.
The inspection method of badminton mesoptile ball is shuttlecock to be got or with the air pressure ejecting device shuttlecock is got with racket by people or machinery, by naked eyes to its flight situation be flight attitude, trajectory stability, flatness and speed or flying distance is observed and carry out the grade inspection and the screening of shuttlecock.
Yet, this inspection method needs the space such as the gymnasium that allow shuttlecock fly, in addition because be with the naked eye to check, also need judge its flight situation in the short time (about 2 seconds) of shuttlecock flight, require to judge skillfully for this reason, and also be easy to generate error in judgement simultaneously.
The object of the present invention is to provide a kind of flight situation that can under the situation in the space that does not need to get shuttlecock, check, judge shuttlecock and speed, can be easy, objective, inspection method and the device thereof promptly checking, judge.
For achieving the above object, the present invention by the following technical solutions.
At first, be the inspection method of shuttlecock of the present invention, its characteristics are: will put into the wind-tunnel internal upper part as tested shuttlecock of having a medical check-up, and it is swum because of running into the lamina air flow that comes from vertical lower, thereby this floating state is observed.And preferably make airflow in the barrel member of the garden of minor diameter, produce lamina air flow to the circulation of wind-tunnel internal upper part.
Second, it is the testing fixture of shuttlecock of the present invention, comprise: the shuttlecock inspection portion that constitutes by the cylinder wind-tunnel of vertical direction setting, the straight laminar flow generating unit of airflow uniformly that upwards provides roughly from cylinder wind-tunnel lower end, air is sent into the fan motor portion of laminar flow generating unit and wind speed control device portion.
And, be preferably with in the laminar flow generating unit under the inspection portion of fan motor portion above just with the fairing that a branch of small diameter cylinder member stops up, make wind speed import bore and regulated by the air that change be added to the voltage on the fan motor or change feed fan motor portion.
The present invention swims this shuttlecock by above-mentioned shuttlecock being provided the lamina air flow that comes under the vertical direction in wind-tunnel portion, thereby its floating state is observed; And can check the flight situation and the speed (or flying distance) of shuttlecock by changing wind speed (air quantity).The airflow that offers shuttlecock must become basic airflow (laminar flow) uniformly in wind-tunnel portion, can have to make the airflow sent from fan motor by a laminar flow generating unit that has the fairing of the cylinder element binder structure of a branch of minor diameter (internal diameter 15-40mm) for this reason.
It is 80～300mm that wind-tunnel portion locates its internal diameter in shuttlecock inspection portion, and is good with 110～250mm, so as to shuttlecock in the inspection portion of this wind-tunnel portion come-up, revolution or be partial to situation such as this inspection portion inwall and observe and make and check and judge.For this reason, the best at least a portion of inspection portion is a hyalomere, and is preferably with the mechanism that can observe shuttlecock revolution situation.In addition, the wind speed of control device portion in should be able to controlling wind-tunnel portion, preferably also have the mechanism that can control the temperature in the wind-tunnel portion, humidity etc.
Simple declaration for accompanying drawing.
Fig. 1 roughly forms the side view of situation for explanation shuttlecock testing fixture of the present invention.
Shuttlecock testing fixture of the present invention is described in more detail by embodiment below in conjunction with accompanying drawing.
Fig. 1 roughly forms the side view of situation for explanation shuttlecock testing fixture of the present invention.Among the figure, the 1 wind-tunnel portion of stretching out for vertical direction, its top is shuttlecock inspection portion 2, its underpart then is a laminar flow generating unit 3.Intersection in inspection portion and laminar flow generating unit is equipped with grid material 4, then is placed on this above grid material 4 as the tested shuttlecock K that haves a medical check-up.
The size of shuttlecock testing fixture each several part can be determined according to needs separately, but laminar flow generating unit 3 becomes roughly uniform laminar flow for making airflow in wind-tunnel portion 1, the fairing 5 that many bundle cylinder elements 50 are stopped up preferably is housed; The internal diameter of cylinder element 50 is 15～40mm, and length is 20～60cm.And the internal diameter that can make wind-tunnel portion 1 is 11～25cm, and the length of inspection portion 2 is 20～40cm, and the length of laminar flow generating unit 3 is 38～80cm.In addition, between cylinder element 50 and grid 4, be preferably formed as the spatial domain 6 of 5～15cm.
Positive bottom in laminar flow generating unit 3 is provided with fan motor portion 7, and the fan 8 that wind speed (air quantity) is provided to the confession air is equipped with in its inside.In this fan motor portion 7 and be provided with to its control device of controlling 9, usually can be by wind speed (air quantity) being changed to added voltage is controlled.Control air humidity and temperature controlling mechanism preferably are housed in this control device 9.In addition, also can regulate air capacity by the bore that the air introducing port 10 of fan motor portion 7 is led in control comes wind speed is controlled.11 is display part among the figure.
In addition, the upper part of inspection portion 2 can be simple cylindric, promptly becomes bell mouth shape 20 but preferably enlarge upward.Can prevent from like this to fly out from inspection portion 2 as tested shuttlecock of having a medical check-up.
Shuttlecock K is dropped in the inspection portion 2 of this shuttlecock testing fixture, by send into certain wind speed (air quantity) to shuttlecock K it is swum, regulate the wind speed of giving and observe the turn state of shuttlecock and bias conditions etc., its flight, speed etc. are checked and are judged.
Being examined shuttlecock promptly does revolution on the roughly certain position in inspection portion and swims after reaching certain wind speed (air quantity).Wind speed (air quantity) according to this moment can be obtained its speed or flying distance.Further judge that according to the revolution floating state its flight situation is flight attitude, ballistic stability and flatness again.
The shuttlecock of flight situation poor (grade is low) is that the revolution of spindle has skew (revolution has runout), or the position instability of swimming, or rotating speed especially slowly or fast especially.The flight situation is poor especially to be meant that then shuttlecock can not continue revolution and swim, touches inspection portion inwall, can not turn round with floating state.
As mentioned above, the present invention can not get actually and easily its characteristic checked under the situation of shuttlecock and judged.
