Reason.
The following are second of specific embodiments of tread pattern pitch automatic generation method provided by the present application, please refer to figure
2, Fig. 2 be the method flow diagram of tread pattern pitch automatic generation method in the application second embodiment, specifically:
Step 201, according to the width of the tire circumference of input and several pitches, putting in order for pitch is automatically generated.
It is understood that putting in order either user is customized for pitch, it can also be according to wheel set by user
The width of tire perimeter and several pitches of input, automatically generates and suitably puts in order.Such as: certain tire circumference is L, definition
3 kinds of pitch widths, respectively A pitch, B pitch and C pitch；
The width of A pitch: W1；
The width of B pitch: W2；
The width of C pitch: W3；
By calculating, tire circumference L is just equal to 5 A pitches, 4 B pitches, the beam overall of 3 C pitches, in total 12 flowers
Line pitch, therefore what can be automatically generated puts in order as AABCACBABACB.The formulation rule that wherein pattern pitch puts in order
It can then be formulated according to requirements such as noise, energy and coefficient of frictions.
Step 202, the pitch width of several pitches and putting in order for pitch are obtained.
It should be noted that the pitch width obtained and the pitch inputted for user in step 201 that puts in order are wide herein
The joint slope sequence spent and automatically generated.In addition, by putting in order to automatically generate in this present embodiment, therefore be not present
Putting in order for pitch is unsatisfactory for the case where tire circumference requires, but may still not meet user's design philosophy, because
And this step can also be expanded, such as: being unsatisfactory for requiring if putting in order, return step 201 reacquires.
Step 203, according to the incidence relation of pitch and decorative pattern, classify to pitch.
In the embodiment of the present application, pitch is divided for 4 seed types, the flower of independent pattern pitch, forward-backward correlation is respectively as follows:
The pattern pitch of line pitch, combination pattern pitch and combination and forward-backward correlation.
Independent pattern pitch (such as Fig. 3): referring to the decorative pattern in pitch, only with when front span it is related, the shape of front back pitch
Shape, size are not related, can carry out independent cutting to pitch by pitch separator bar or groove, adjacent different pitches it
Between can be seamless spliced and sorted.Such as:
A pitch width: W1
B pitch width: W2
C pitch width: W3
By calculating, tire circumference is just equal to the beam overall of 5 A pitches, 4 B pitches, 3 C pitches, in total 12 sections
Away from.Assuming that the pitch sequence drafted are as follows: AABCACBABACB has 3 kinds of pitches in one tyre tread, and 3 kinds of pitches are only
Vertical existing, as long as not changing the quantity of 3 kinds of A pitch, B pitch and C pitch pitches in tire sequence, above sequence can be with
Arbitrary adjustment position, is such as changed to: BAAACCBABACB can be generated new as long as adjusting the sequence of positions of several pitches
Tyre tread.
The pattern pitch (such as Fig. 4) of forward-backward correlation: referring to the shape when the decorative pattern (groove/ditch geosynclinal block) in front span N, be by
Before the shapes of (rear) one or more pitches influence, in the ranking, need the front and back pitch relationship for considering to work as front span.Still
Above-mentioned sequence AABCACBABACB is quoted, such as some decorative pattern shape in pitch N, is determined by the size of N+1 pitch.Work as prosthomere
Away from for A, N+1 pitch have 3 kinds may: A, B or C, then the shape of A pitch, there are 3 kinds of possibility, i.e. A (A), A (B) and A (C).
Combination pattern pitch: refer to that multiple groups pitch collectively forms one group of groove/ditch geosynclinal block, with above-mentioned AABCACBABACB this
For a decorative pattern sequence, if two adjacent segments share AA, BC, AC, BA, CB, 5 kinds of groups away from one group of groove/ditch geosynclinal block is constituted
It closes, wherein BA combination occurs twice.
The pattern pitch of combination and forward-backward correlation: (such as Fig. 5) refers to when certain groove/ditch geosynclinal block in front span, while across
N pitch (n >=2) is got over, such as first groove and Article 2 groove in Fig. 5, shape and the technique of painting are different, simultaneously
2 pitch controls are spanned, the decorative pattern shape for the combination pitch that AB is formed also is influenced by the latter pitch C.
Step 204, parametrization pitch model is established according to classification results.
It is understood that each classification has its feature, if the decorative pattern when front span is associated with front and back pitch,
The pitch model then parameterized needs the incidence relation according to front and back pitch just to establish.
Step 205, according to parametrization pitch model, the built-up pattern of all unduplicated pitches and decorative pattern is generated.
By taking the sequence of this decorative pattern of AABCACBABACB as an example:
If independent pattern pitch, then tri- kinds of pitch A, B, C of pitch model is established respectively；
If the pattern pitch of forward-backward correlation, and when front span decorative pattern only with later section away from it is associated, then need to establish A
(A), A (B), A (C), B (A), B (C), C (A), C (B), 7 kinds of models (because B (B) and C (C) are not present in sequence).If A is saved
It is to be determined by the multiple pitch sizes in front and back away from shape, then a possibility that this A pitch will be very big, there are multiple combinations
Situation.If: A pitch is by previous pitch and latter pitch size joint effect, then the sequence of A pitch may be C (3,1) * C
(3,1)=9 kind combination, with increasing for association pitch quantity (such as 4 pitches, 5 pitches etc.), then the combination of pitch shape will
With increasing；
If combination pattern pitch, and two adjacent segments away from constitute one group of groove/ditch geosynclinal block, then share AA, BC, AC, BA,
CB, 5 kinds of models；
If combination and the pattern pitch of forward-backward correlation, and two adjacent segments away from constituting one group, i.e., first group is AA pitch.
Assuming that AA pitch is also influenced by former and later two pitch decorative patterns, therefore when pattern pitch modeling, by across multiple sections
Away from that will be modeled, i.e. foundation (B) AA (B), (A) BC (A), (C) AC (B), (C) BA (B), (A) BA (C), 6 kinds of (A) CB (A)
Model.Another is to be extended to more complicated situation: wherein N-1, N-2 may also influence whether the shape of AA pitch, then, at most deposit
In C (3,1) * C (3,1) * C (3,1) * C (3,1)=81 kind of ordering scenario.As combination pitch quantity is associated with pitch quantity (such as 4
Pitch, 5 pitches etc.) increase, then the combination of pitch shape will be with increasing.
It is ordered as case with a decorative pattern to be further described, equal pitch A B C, decorative pattern do not sort 3 width are as follows:
CABCACACBABAAABACABCBABABCBACCBACBBA obtains the advance of this decorative pattern from pattern pitch parameterized model
Pitch incidence relation and pattern pitch type calculate different repetition decorative pattern results according to different pattern pitch types:
1, independent pattern pitch, calculated result are as follows: resultant pitch 36, in which: A pitch 14, B pitch 12, C pitch
10, unduplicated pitch is 3, respectively pitch A, pitch B, pitch C；
2, the pattern pitch of forward-backward correlation, because there are a variety of situations for forward-backward correlation relationship, to work as front span (n) and back pitch
(n+1) associated situation is calculated, calculated result are as follows: resultant pitch 36, in which: and A pitch 14, B pitch 12, C section
Away from 10, unduplicated pitch is 9, is respectively as follows: C (A), A (B), B (C), C (B), A (C), A (A), B (B), B (A), C (C)
9 kinds of situations in total (bracket indicates relevant, but combines without pitch)；
3, pattern pitch is combined, to form combination pitch as front span (n) and back pitch (n+1) and front span (n-1)
Situation is calculated, calculated result are as follows: resultant pitch 36, in which: A pitch 14, B pitch 12, C pitch 10, is not repeated
Pitch be 10, respectively CAB, CAC, ACB, ABA, AAB, ACA, BCB, ACC, BAC, BBA, not with pitch combination
Together, repeatedly the quantity of pitch and group credit union do not change；
4, across pitch and the associated pattern pitch of front and back pitch, to be combined when front span (n) is formed with back pitch (n+1)
Pitch, at the same with (n-1), the associated situation of (n+2) pitch calculated, calculated result are as follows: resultant pitch 36, in which: A section
Away from 14, B pitch 12, C pitch 10, unduplicated pitch is 14, is respectively as follows: (A) CA (B), (A) BC (A), (C) AC
(A), (C) AC (B), (C) BA (B), (A) BA (A), (A) AA (B), (A) BA (C), (A) BC (B), (A) BA (B), (C) BA (C)
(A) CC (B), (A) CB (B), (B) BA (C), with the difference that pitch combines, repeatedly the quantity of pitch and the change of group credit union (are not included
