Specific embodiment
The present invention is further discussed below below with reference to embodiment and its attached drawing:
As shown in Figure 1 to 11,
In spool amplitude detection experiment of the invention, consider that spool surface characteristic selects direct-injection type laser measurement principle to yarn
Pipe top amplitude is detected,
The working principle of laser displacement sensor is by the laser emitter in sensor to the tested surface of testee
Emit one laser beam, since scattering or reflex laser beam are irradiated to behind testee surface back to sensor internal
On CMOS image, the distance that sensor is arrived on testee surface, and general are calculated by the internal algorithm of displacement sensor
Displacement is shown on the LED display of sensor, while also being exported the voltage value of corresponding displacement and being sent data collecting card to, is schemed
In 2: α is that laser injects light and detects the angle between datum level, degree；β is light and CMOS image plane after lens transmission
Angle, degree；A is to be measured distance between point and receiving lens, mm；B is the point that returns on CMOS image of measured point and connect
Receive distance between lens, mm；a0、b0To be respectively the measured point after deviating h and the point returned on CMOS image and receiving saturating
Distance between mirror, mm.The basic model of formula (1) amplitude measurement can be obtained according to geometrical relationship:
That is:
In above formula: y is the vibration displacement for measuring object, mm；X is displacement of the picture point on CCD, mm.
If spool amplitude is in above ideal point, formula takes positive sign in (2)；If spool amplitude is in below ideal point,
Formula takes negative sign in (2).
Amplitude data sample mode: data acquisition is mainly irradiated to spool using laser displacement sensor acquisition laser beam
On point (assuming that along beam direction be y-axis direction) along the y-axis direction displacement (amplitude), and spool uniform rotation works as spool
After turning over certain intervals angle delta θ with spindle, amplitude along the y-axis direction is put on laser displacement sensor acquisition spool, spool is adopted
Sample interval angles calculation formula are as follows:
Δ θ=ω Δ t (3)
In formula: ω is spool rotational angular velocity, rad/s；Δ t is sampling time, ms.
ω=π n/30 (4)
In formula: n is spool revolving speed, r/min.
It is obtained by formula (3) and (4):
Sampling number k when spool turns around1Are as follows:
It can be obtained by formula (3), (4) and (5):
Assuming that P circle sampling post-sampling point is overlapped a referred to as sampling period with starting point when first sampling point is 0 degree, it can
:
2P π=k Δ θ k=1,2 ..., N (8)
In formula: k is the points sampled in a cycle.
That is:
Table 1 provides the sampling parameter of sensor different sampling stages.
1 sensor sampling parameters of table
As shown in Table 1: when choosing the sensor sample time is 0.5ms, sampling interval angle is 54 °, and 3 circles are adopted for one
The sample period can acquire 20 points in a cycle.When choosing the sensor response time is 1.5ms, sampling interval angle is
162 °, 9 circles are a sampling period, can acquire 20 points in a cycle.When choosing the sensor sample time is 5ms, adopt
Sample interval angles are 540 °, and 3 circles are a sampling period, can acquire 2 points in a cycle.
In data sampling, the sensor sample frequency known to Nyquis theorem has to be larger than or is equal to tested spool frequency
2 times just can guarantee that sampled point is undistorted, due to spindle revolving speed be 18000r/min, corresponding frequencies 300Hz, therefore sensing
Device sample frequency has to be larger than 600Hz, according to the basic parameter of sensor it is found that the sensor sample time that can be chosen at this time is
0.5ms and 1.5ms.
When data sampling, it is 600HZ that sample frequency is arranged on data sampling software DataLogger, at this time
The data points that data acquisition software can acquire are 6000, among the stability selection in order to guarantee data
600 data are drawn as sample point.
Spool amplitude data Processing Algorithm:
(1) spool amplitude mean value: spool amplitude mean value has reacted the central tendency of amplitude data, expression formula are as follows:
In formula: N is sampled data points sum；xiFor ith sample point.
(2) spool amplitude excursion rate and integral change rate: spool amplitude excursion rate, which refers to, is doing the experiment of spool amplitude detection
When beyond given standard amplitude part detection number account for the ratio of overall test point number, evaluated using spool amplitude excursion rate
Spool, expression formula are as follows:
In formula: α is the spool amplitude threshold of setting, mm.
Above-mentioned DR only represents more than the ratio of spool amplitude threshold point number, also using integral change rate (IDR (%))
Come evaluate spool amplitude be more than threshold value degree, the parameter reacted spool amplitude detected be more than threshold value degree, and should
Value reduces with the increase of threshold value.Its calculation formula is as follows:
System composition and experiment condition: the detection process of spool amplitude detection system mainly passes through laser displacement sensor
The upper vertical for detecting high speed rotation spool is displaced in the yaw of beam direction, and shows displacement on a sensor, together
When corresponding voltage signal passed into data collecting card, finally collected voltage signal is shown on computers.Experiment
System includes spool, laser displacement sensor, workbench, PCI-1711I/O interface, spool speeder and data acquisition software
System, table 2 provide the basic parameter of sensor.The PCI-1711 data collecting card of Yan Hua company production, work are selected in experiment
Make principle and mainly acquire sensor to be transmitted in host computer testee signal detected and analyzed and handled.This reality
Testing middle data collecting card is mainly that the analog signals for sending laser displacement sensor pass to computer, and pass through phase
The software answered shows acquisition signal.
2 sensor basic parameter table of table
In this experiment, the spindle for selecting 205 spools of different wear types and matching carries out amplitude detection, and spindle turns
Speed is 18000r/min, and table 3 provides several wear types of spool,
3 spool wear type of table
Detection system calibration: the calibration of detection system is actually the function expression for determining input/output relation, this
When corresponding voltage change signal value is exported by change in displacement value of the control object from sensor, and utilize least square
Fitting obtains the mathematical function expression formula of input and output, it is assumed that y indicates displacement at this time, and x indicates corresponding voltage output signal.
Its corresponding linear fit function can be obtained by calibration experiment and MTLAB least square curve fitting are as follows:
Y=2.0007x-4.9937 (15)
According to spool difference wear type shown in table 3 to spool carry out amplitude detection experiment, wherein amplitude threshold α according to
The evaluation criterion of new spool amplitude suitably selects three groups of 0.3mm, 0.4mm and 0.5mm etc. to be tested, and lists each group spool
Amplitude data gets corresponding results as follows:
1, there is no bias for spool mass center
(1) top completely attaches to lower base opening and also contacts well
Table 4 is given at the group and tests lower ten spool amplitude statistical results, and Fig. 7 is No. 1 spool amplitude curve figure, selection
600 data points are drawn as sample point.
From table 4 and Fig. 7: spool is not eccentric and completely attaches to spool vibration when lower base opening also contacts good with spindle upper section
The maximum value of width, minimum value and amplitude mean value are all smaller, and when amplitude threshold is 0.3mm, it shakes known to spool amplitude excursion rate
Width deviation ratio is all larger, and with the increase of amplitude threshold, amplitude excursion rate is gradually reduced, especially when threshold value is 0.5mm ten
The amplitude excursion rate mean value of branch spool is 0.043%, substantially close to 0, illustrates that spool amplitude fluctuation at this time is most of given at it
In amplitude standards threshold value；Change rate mean value is integrated by amplitude and is reduced to its amplitude integral change rate known to 0.004% from 17.06%
Also with amplitude threshold increase and reduce or even be close to 0, illustrate that amplitude is more than the degree of given amplitude threshold with threshold at this time
The increase of value and reduce.The amplitude threshold known to three amplitude excursion rate mean values is selected as its amplitude excursion rate when 0.3mm and 0.4mm
Mean value is respectively that 64.04% and 22.68% are all larger, and its amplitude excursion rate mean value is when amplitude threshold is 0.5mm
0.043%, amplitude is swung in given amplitude threshold substantially, is substantially conformed to using rear spool Eligibility requirements condition, therefore can
It is appropriate to should be 0.5mm for amplitude Evaluation threshold when proposing the spool qualification after use.And actually detected amplitude ratio out is same
The amplitude that ADMAS emulation obtains in the case of kind contact is somewhat larger, the main reason is that being the yarn after used in experiment
It manages and not eccentric and some other influence factors that spool be unable to completely control also will affect the size of its amplitude, but two
Person's amplitude curve is substantially similar, and amplitude is all smaller, and variation is also more uniform, meets experiment expected results.
4 spool amplitude statistical result of table
(2) it is good to damage lower base opening contact for top
Table 5 is given at the group and tests lower ten spool amplitude statistical results, and Fig. 8 is No. 7 spool amplitude curve figures, selection
600 data points are drawn as sample point.
From table 5 and Fig. 8: spool it is not eccentric and contacted with spindle upper section damage and lower base opening contact it is good when its threshold value
It is respectively 86.17%, 61.14% and 17.35% for the amplitude excursion rate mean value of 0.3mm, 0.4mm and 0.5mm, with former reality
Amplitude excursion rate mean value 64.04%, 22.68% is compared with 0.043% in the case of testing significantly increases, and illustrates spool amplitude number at this time
Strong point increases beyond the quantity of its given amplitude threshold, and spool amplitude fluctuation is obvious, and amplitude integral change rate mean value equally increases
Add obvious, degree increase of the amplitude more than given amplitude threshold at this time.Therefore under such contact conditions spool amplitude variations compared with
Greatly, amplitude departure degree obviously increases.When being selected as 0.4mm or less by amplitude threshold known to three amplitude excursion rate mean values its
Data point ratio beyond amplitude threshold reaches 60% or more, illustrate to select amplitude threshold for 0.4mm and following and do not conform at this time
It is suitable, and its amplitude excursion rate is 17.35% when amplitude threshold is selected as 0.5mm, thus select at this time amplitude threshold for 0.5mm compared with
It is suitable.Since the contact number of segment in upper contact face can not be accurately controlled in experiment, top can not be simulated well
The contact situation of contact surface, but the result that experiment obtains is similar with the result that upper contact surface wear will increase spool amplitude,
The abrasion for demonstrating spool and spindle upper section contact surface will increase the conclusion of spool amplitude.
5 spool amplitude statistical result of table
(3) upper contact well descends base opening to damage
Table 6 is given at the group and tests lower ten spool amplitude statistical results, and Fig. 9 is No. 10 spool amplitude curve figures, selection
600 data points are drawn as sample point.
From table 6 and Fig. 9: spool is not eccentric and its amplitude maximum when contacting well lower base opening damage with spindle upper section
Increase compared with first two experimental conditions with minimum value larger, amplitude excursion rate mean value is respectively 91.98%, 63.24% and
31.43%, it is all bigger than the amplitude excursion rate under first two experiment condition, illustrate the influence for descending base opening to wear to spool amplitude at this time
It is bigger, and its amplitude integral change rate mean value is respectively 35.63%, 18.08% and 8.21%, amplitude departure degree increases bright
It is aobvious.Equally by amplitude threshold known to three amplitude excursion rate mean values be selected as 0.4mm and it is following when its data for exceeding amplitude threshold
Point ratio reaches 60% or more, and when amplitude threshold is selected as 0.5mm, its amplitude excursion rate is 31.43%, therefore is selected at this time
Amplitude threshold is that 0.5mm is more appropriate.Illustrating that amplitude dispersion degree is big under such experiment condition, amplitude fluctuation phenomenon is serious,
Its amplitude is close with the amplitude simulation value in situation of the same race simultaneously, and amplitude is very big in such cases, illustrates that spool is gone to the bottom
Mouth abrasion influences the size of spool amplitude and impact effect is obvious.
6 spool amplitude statistical result of table
(4) top and lower base opening are all damaged
Table 7 is given at the group and tests lower ten spool amplitude statistical results, and Figure 10 is the smallest No. 6 spools vibration of amplitude mean value
Width curve graph selects 600 data points to draw as sample point.
From table 7 and Figure 10: when spool is not eccentric and top and lower base opening are all damaged its amplitude minimums and mean value with
For preceding several experimental conditions compared to all larger, amplitude excursion rate mean value is respectively 93.33%, 77.00% and 49.77%, is reached
It is several contact situations maximum values, illustrate spool top at this time and lower base opening all wear be to spool amplitude influence maximum, and
Its amplitude integrates change rate mean value difference 46.53%, 30.55% and 19.52%, and amplitude departure degree increases obvious.Illustrate this
When amplitude fluctuation it is very violent, spool is obviously unqualified, thus explanation when spool top and lower base opening abrasion will increase its amplitude
Value, and spool yaw acutely easily leads to Yarn tension fluctuation and Yarn break.
7 spool amplitude statistical result of table
2, spool mass center exists eccentric
Top completely attaches to lower base opening and also contacts well
Table 8 is given at the group and tests lower ten spool amplitude statistical results, and Figure 11 is the smallest No. 5 spools vibration of amplitude mean value
Width curve graph selects 600 data points to draw as sample point.
From table 8 and Figure 11: spool is eccentric and completely attaches to spool vibration when lower base opening also contacts good with spindle upper section
Width maximum value, minimum value and mean value all increased compared with when spool is not eccentric, and amplitude excursion rate mean value is respectively
93.84%, 61.87% and 10.46%, there is apparent increase compared with amplitude excursion rate mean value when spool is not eccentric, illustrates yarn
The bias for managing itself will increase spool amplitude fluctuation；It is 30.88%, 11.87% and 2.55% that its amplitude, which integrates change rate mean value,
17.06%, 2.32% and 0.004% equally compared to spool when not eccentric is big, and amplitude is more than given amplitude threshold at this time
Degree increase.Therefore spool amplitude variations are obvious under such experiment condition, and amplitude departure degree increases, amplitude fluctuation
Yarn tension fluctuation and Yarn break obviously are easily led to, will increase the conclusion phase one of spool amplitude with the spool bias of analysis
It causes.
8 spool amplitude statistical result of table
The present invention is directed to spool amplitude detection problem, and it is flat to build the experiment of spool amplitude detection using laser displacement sensor
Platform carries out amplitude detection to the spool of different wear types, has obtained spool amplitude under various experiment conditions；And utilize this hair
The spool amplitude data evaluation algorithms of bright proposition, finding out amplitude threshold under each experiment condition is respectively 0.3mm, 0.4mm and 0.5mm
When amplitude excursion rate and integral change rate, can finally be concluded that
(1) amplitude excursion rate and integral change rate reduce with the increase of amplitude threshold, by comparing each experiment condition
Under three amplitude excursion rate mean values and integral change rate mean value known to amplitude threshold be selected as 0.4mm and it is following when its beyond amplitude
The data point ratio of threshold value is higher, and amplitude departure degree is also more obvious；And its amplitude is inclined when amplitude threshold is selected as 0.5mm
Shifting rate is also small compared with short arc departure degree, substantially conforms to using rear spool amplitude detection Eligibility requirements, therefore selects amplitude threshold
It is relatively reasonable as spool amplitude Evaluation threshold for 0.5mm.
(2) when amplitude threshold is 0.5mm, spool is not eccentric and amplitude excursion rate and integral change rate when contacting good up and down
Respectively 0.043% and 0.004%, and spool is eccentric and amplitude excursion rate and integral change rate are respectively when contacting good up and down
10.46% and 2.55%, hence it is evident that than it is not eccentric when amplitude it is big, illustrate that the eccentric phenomena of spool will increase the amplitude of spool.
(3) abrasion of spindle and spool faying face will increase spool amplitude excursion rate and integral change rate, and with abrasion
The increase spool amplitude excursion rate and integral change rate of area also increase.
(4) when amplitude threshold is 0.5mm, amplitude excursion rate and integral change rate when base opening is worn under spool are respectively
31.43% and 8.21%, than under other experiment conditions amplitude excursion rate and integral change rate it is all high, especially when occurring on spool
Under when all wearing its amplitude excursion rate and integral change rate reach maximum, illustrate that base opening abrasion influences most spool amplitude under spool
Greatly.
