Very little rationally can arrange according to practical application request, its size affects speed, and general size more slight drag is the least, and moment of torsion is more
Greatly, so driving force is the strongest, but speed is the slowest.
The swash width self calibration principle that this utility model relates to is described as follows:
With reference to Fig. 2, in actual applications, it is assumed that need to measure arrow position number of coordinates when rocket body injects archery target 17
According to, in order to improve precision and the reliability of measurement, therefore need a selected reference value, such as, can select with reference to such as institute in Fig. 2
In the system shown, active drive wheel 12 any one passive scanning head of control total travel single-way moving on its limit, place once obtains
The formula arrived:
Dsize=Ls/Nstep (1)
Assuming that the radius that active drive is taken turns is R, in theory, active drive wheel often rotates/takes a step forward, corresponding probe
The distance of movement is:
Dsize=2 π R Φ (2)
Wherein, DsizeThe distance that when often rotating/take a step forward during for active drive wheel 12 control, probe moves, i.e. scans
Step-length, that is to say the stepping-in amount parameter of active drive wheel 12, LsIt is the distance between two stops, NstepTake turns for active drive
12 control the step number advanced when probe sequentially passes through two stops, and R is the radius of active drive wheel 12, and Φ is active drive
Wheel 12 often rotates/takes a step forward rotated angle.
Formula (2) is substituted in formula (1) it follows that
Ls=2 π R Φ * Nstep (3)
By formula (3) it can be seen that when not using the stop that the utility model proposes, passive scanning head is at its place
On limit, total travel single-way moving distance L would generally be subjected to the condition impacts such as ambient temperature and cause active drive wheel half
The change in footpath or the change of coiling degree of tightness, cause its numerical measuring error relatively big, and due to the manufacturing process of active drive wheel 12
And the impact such as product batches, the distance i.e. scanning step that will cause each stepping equally and the distance often enclosing stepping differ
Cause, therefore a series of cumulative error (open error) will be produced, ultimately result in the unreliable, by mistake of arrow position measurement result
Difference is the most invalid relatively greatly.The utility model proposes the design using start point/end point stop, at passive scanning head on its limit, place
Upper total travel single-way moving distance (L) two-end-point introduces position and limits detection, and is used for calibrating or extrapolating Dsize, and then permissible
By distance L between two stopss(as in figure 2 it is shown, when two stops are arranged on the swash width two ends of passive scanning head
During point, Ls=L) between any error be all defined to an error closed, therefore can determine accurately and such as actively drive
Driving wheel 12 often walks the reference values such as the distance of advance is how many, therefore and then swash width can be carried out real-time implementation self calibration (i.e.
Passive scanning head total travel single-way moving distance L is carried out self calibration), to revise at any time owing to expanding with heat and contract with cold or coiling degree of tightness etc.
The change of the scanning step that outside cause causes, it is ensured that certainty of measurement under circumstances.
It is hereby stated that, described above contribute to skilled artisan understands that the invention, but and the unrestricted present invention
The protection domain created.Any equivalent described above, modification are improved without departing from the invention flesh and blood
And/or delete numerous conforming to the principle of simplicity and the enforcement that carries out, each fall within the protection domain of the invention.
