Description
Technical field
The present invention relates to bearing inspection technology field, more particularly, relate to a kind of test method of bearing fault.
Background technology
The bearing failure fault is headachy problem during bearing is used.Bearing failure may be caused that by many reasons in the bearing that breaks down, the performance of many reasons occurs simultaneously sometimes, and therefore can't differentiating on earth, that a kind of reason is only the main cause that causes bearing fault.If can't effectively differentiate the main cause that causes bearing failure, the potential faults of bearing exists all the time so.
A kind of mode of seeking the bearing failure reason is to carry out a large amount of tests, and simulation causes the possible cause of fault respectively.By the test findings that lot of experiments obtains, seek the main cause that causes bearing fault.Lot of experiments obviously is mode uneconomical and consuming time.
In recent years, the development of Orthogonal Experiment and Design (Orthogonal experimental design) provides a kind of test method that can reach by the test of lesser amt valuable result.Orthogonal test is the multifactor multilevel a kind of method for designing of research, it is to pick out the representational point of part according to orthogonality from comprehensive test to test, these representational points have possessed the characteristics of " Uniform Dispersion; neat comparable ", and Orthogonal Experiment and Design is the main method of fraction Factorial Design.A kind of high-level efficiency, quick, economic experimental design method.
Summary of the invention
The present invention is intended to propose a kind of test method of utilizing the bearing fault of orthogonal test method.
According to one embodiment of the invention, a kind of test method of bearing fault is proposed, comprise following step:
Obtain bearing fault information, bearing fault information is classified;
Bearing fault information according to classification generates one group of fault factor;
Based on this group of fault factor, produce many group test parameterss according to the orthogonal test rule;
Carry out many group test parameterss and collect the index that each organizes test parameters;
Calculate the weight of each fault factor according to index.
Wherein, based on this group of fault factor, produce many group test parameterss according to the orthogonal test rule and comprise that generation comprises the orthogonal arrage of several fault factors.This orthogonal arrage comprises the various combination of the fault factor.
The test method of bearing fault of the present invention is utilized the principle of orthogonal test, and the test by limited number of time just can access valuable data, finds the main cause that causes bearing fault, can Effective Raise bearing power of tests rate accuracy rate.
Description of drawings
Fig. 1 has disclosed the process flow diagram according to the test method of the bearing fault of one embodiment of the invention.
Embodiment
When the experiment number of minute factorial designing requirement was too many, a very natural idea was exactly from the horizontal combination of Factorial Design, selects a part of representative horizontal combination to test.Therefore fraction Factorial Design (fractional factorial designs) just occurs, but for the less working people of test design knowledge, has selected suitable fraction Factorial Design still relatively difficult.For example do the experiment of a Three factors-levels, by comprehensive requirement of experiment, must carry out the experiment of 33=27 kind combination, and not yet consider the repeat number of each combination.If press L9 (3) 3 orthogonal arrages by row's experiment, only need to do 9 times, carry out 18 experiments by L18 (3) 7 orthogonal arrages, obviously greatly reduced workload.Thereby orthogonal is used widely in the research in a lot of fields.
The principal feature of orthogonal test method is: (1) in the less situation of test number (TN) to more Test Information; (2) effectively isolate effect size and the delineation factor interaction of each factor.In essence, the testing site is evenly distributed in feasible zone and occupy fully large space as far as possible.Say exactly on orthogonal test method is concrete and will use suitable orthogonal arrage, some levels that several factors are arranged are arranged to consist of how group is tested by the position of orthogonal arrage, then carry out each factor effect with regard to test findings (index) and adopt the method for mathematical statistics to analyze.
Use for reference orthogonal test method, imagine a kind of being applied as: index regard as a certain phenomenon the degree (such as number percent) that under the different manifestations combination, occurs, each shows and is equivalent to the factor, different levels then is considered as the different aspect of same performance.Utilize orthogonal test principal feature (2) just can analyze a certain phenomenon different manifestations between relation.On the meaning of reality, can catch principal contradiction that foundation is provided for dealing with problems.
Based on above-mentioned principle, the present invention proposes a kind of test method of bearing fault, and with reference to shown in Figure 1, this test method 100 comprises:
101. obtain bearing fault information, bearing fault information classified.
102. the bearing fault information according to classification generates one group of fault factor.
103. based on this group of fault factor, produce many group test parameterss according to the orthogonal test rule.In one embodiment, this step 103 comprises that generation comprises the orthogonal arrage of several fault factors.In one embodiment, orthogonal arrage comprises the various combination of the fault factor.
104. carry out many group test parameterss and collect the index that each organizes test parameters.
105. calculate the weight of each fault factor according to index.
The below lifts an instantiation and describes:
For example, in the bearing that client's claim is return, the main bearing failure form of expression is:
1) fatigue flake;
2) seal failure.
Wherein, fatigue flake is rendered as interior raceway and peels off with outer raceway and peel off.Seal failure shows as grease and does with grease black.Two kinds of failure modes may show on the bearing simultaneously.Which is the main cause that causes bearing failure in these two factors on earth, be to cause seal failure after the fatigue flake heating, or seal failure causes fatigue flake, or both is not relevant, and this need to decide by test.
In above problem description, the relation between each level be different from resemble between the conventional test level the difference of amount just, but a kind of difference of non-amount.The difference that very large matter may be arranged in case of necessity.This is not matter of principle.Because say in essence, the factor or corresponding test findings or the phenomenon of performance are a kind of funtcional relationships, and argument of function also can be set.According to real data, the orthogonal arrage of above problem is established as:
Test based on above-mentioned orthogonal arrage, can obtain following conclusion: go out bearing failure and mainly caused by fatigue flake, it is very little on the bearing failure impact to leak fat.Because peel off with the reciprocation that seals greater than leaking fat effect 67%, therefore, can think: the fatigue flake heating has caused seal failure.
The test method of bearing fault of the present invention is utilized the principle of orthogonal test, and the test by limited number of time just can access valuable data, finds the main cause that causes bearing fault, can Effective Raise bearing power of tests rate accuracy rate.
