Description
Technical field
The present invention relates to the method that dynamic quantitative adjusts bow calibration altogether.
Background technology
Arrow Zhi Zuowei elongate resilient structure, when quickly being promoted by bowstring, arrow shaft is squeezed and " stock unstability " occurs,
Natural resiliency attempts to recover original form again simultaneously, and therefore arrow props up after being launched until stopping this period one flown completely
Directly constantly vibrate in oneself is as the vibrations plane of reference frame.And in order to improve fire accuracy further stabilized flight attitude, use
It is designed to have the aerodynamic characteristics of propeller blade structure in the stabilizer " fletching " that the accurate arrow shot props up afterbody, make arrow
Awing can do rapid circular movement along own axes, thus this kind of arrow prop up in flight course can by " thrust ", " vibration ",
" gyroscopic procession " producing after " rotation " and rotation 4 makes a concerted effort to arrange.Therefore arrow Zhi Feihang macroscopic view becomes parabolic motion, microcosmic
Become complicated spiral vibrating.
Bow as the transmitting main body propped up of arrow in the fabrication process due to the error accumulation after multiple part combination, in coupling not
With purposes, the different arrow of diameter, length, quality, elasticity props up.So that the geometry of machinery center of bent body can be deviateed " in transmitting
The heart ", if geometric center of only bending low replaces launching centre.Arrow prop up flight course easily occur arrow prop up swing and take aim at tool scale cannot
Corresponding with shooting distance, firing dispersion was once big.So all bow-arrows for accurate shooting have to pass through " zero " to find very
Positive launching centre,
And this operation must pass through serial of methods constantly groping property adjustment by professional, and eventually through penetrating
Handss determine zero result after repeatedly reality is shot.After equipment is zeroed and pays, during other shooter, different shooter's handle postures differ
Cause or kinestate not good it is possible to lead to be zeroed unsuccessfully, further increase debug time.
Existing three kinds of existing common methods：Static method, broken paper method, polished rod-plumage arrow method.
In said method, " static method " return-to-zero-time is the shortest low in pulling force under conditions of having professional equipment, bow and arrow equipment
Basic shooting demand can be met under conditions of energy is excellent.Shortcoming is that bow and arrow equipment does not stress in debugging, is in free shape
State.And " launching centre " essence that in actual shooting course, " static method " is obtained is geometry of machinery center.This position is arrow
Zhi Sudu is maximum and position that will leave bowstring.Now arrow props up and obtains enough kinetic energy.Arrow platform can not constrain what arrow propped up
Movement locus, and arrow propped up at the initial stage accelerating（Arrow platform, arrow nest energy stability contorting arrow prop up the critical period of movement locus）It is in
Bowstring angle, arculae deformation, the maximum position of bent body stress.Because shooter can lead in the difference launching handle posture when arrow props up
Launching centre deviates geometric center, leads to and actual transmission center deviation, causes flight path that arrow props up and sets up result
Larger deviation occurs, is only used as zero means the most rough.
Must also be repaiied by tediously long " broken paper method " and " polished rod-plumage arrow method " for the high accuracy zero in athletics sports project
Just.Because archery action differs greatly, when shooter's handle is also occurred when different from point of application when being zeroed to the point of application of bent body
Deviation, or even occur completely offseting from scope and lead to be zeroed unsuccessfully.So existing tune bow method needs commissioning staff to have athlete
The professional and technical personnel of rank and shooter's cooperation.The adjustment time length of a set of bow and arrow equipment and precision are with the experience of commissioning staff
And proficiency level.Cannot carry out in batches being quantified with process, subjectivity is strong.
