Further, it is determined that after the failure cause of the failure part, the Materials failure analysis method further include:
Failure cause is verified；
According to failure cause, change scheme is proposed to failure part.
It is proposed change scheme after, then by after change part carry out verification test.If verification test success, illustrates to fail
Reason is correct, can import the related data of the case in material failure analysis database, so as to subsequent access.If tested
Confirmatory test is unsuccessful, then is searched again failure cause.
Material failure for Cracking Failure, is illustrated when road test is tested by a certain C platform vehicle rear stabilizer bar clip below
The detailed process of analysis method can refer to Fig. 3, specifically,
Obtain the failure background of failure part；
In an embodiment of the present invention, the failure background of auto parts include fail part loading conditions, assembly situation,
Situation when situation when use, failure, the title for the part that fails and failure part estimate failure mode etc..Estimate failure mode packet
Include fracture failure, deformation failure and surface damage failure.
The effect of stabiliser bar clip is fixed stably fixed pole；It is primarily subjected to cyclic load；In road test about 50%, staff
When checking vehicle-state, discovery clip corner cracking.Clip failure belongs to fracture failure.
Visual examination is carried out to failure part, obtains the fail message of failure part；
Fail message include fail part integral status, failure part where position, failure part where system and/or
Field conditions, failure part and matching relationship of other adjacent components etc. where when failure part failure.System where failure part
System includes engine system, chassis system, bodywork system, automobile electric appliance system etc..Can also to failure part and failure site into
It line flag and photographs to record, to save data.
It searches in Materials failure analysis database and matches with the failure background of the failure part and/or fail message
Material failure data, obtain and estimate failure cause；
In Materials failure analysis database, the case same or similar with this case failure mode and/failure background is searched
Example, as reference.For example, inputting " clip " search in the part name in Materials failure analysis database, database is obtained
Query result, as shown in Figure 4.It opens data one by one to be inquired, wherein the failure mode of clip is related to K platform in this case
LWT-MAT-2036,2063,2133,2150 and 2163 failure describes similar, and failure cause is turning transition arc
There are the micro-flaws of bending at place, then the failure cause of estimating of clip is that there are the micro- of bending at the transition arc of turning in this case
Crackle.
According to failure cause is estimated, fracture observation is carried out to failure part, obtains fracture information；
Observation of the fracture observation including fracture after the observation and cleaning of original fracture.Observation method has two classes, respectively low
Observation and high power observation again.Low power observes predominantly visual, hand magnifying glass, and Stereo microscope etc. is observed；High power is seen
It examines mainly using scanning electron microscope, transmission electron microscope etc. observes fracture.
In an embodiment of the present invention, since clip is only cracking, not fracture completely.At this time, it may be necessary to which fracture is cut
It opens, after fracture is cleaned, carries out high power observation using scanning electron microscope.Low power sight first can also be carried out to original fracture
It examines, then cleans fracture, carry out high power observation.
According to fracture information, failure mode is determined；
Failure mode includes fatigue, abrasion, corrosion and/or fracture etc..According to fracture as a result, inferring the mistake of failure part
Effect form: according to trace tired on fracture as a result, failure mode is determined as fatigue fracture.
Failure part is compared and analyzed with the part that do not fail using material analysis method, obtains comparing result；
Material analysis method includes: size detection, metallographic detection, mechanical performance, non-destructive testing, composition detection and stress point
Analysis etc..Wherein, the detection project of metallographic detection includes crystallite dimension, surface treatment, heat-treated sturcture and microdefect etc.；It is mechanical
The detection project of performance includes: hardness, compression, stretching, bending and impact flexibility etc.；The detection project of non-destructive testing includes whirlpool
Stream, magnetic powder, ultrasonic wave, CT and internal stress test etc.；The detection project of composition detection includes fracture ingredient and matrix composition etc.；It answers
The detection project of power analysis include using when load and stress distribution etc..
Detection point is compared to failure part and the part that do not fail using one or more of material analysis method
Analysis, detection project can also choose one or more, find out difference between the two by Determination, obtain comparison knot
Fruit.Not failing part can be using by the identical parts on part or import parts or unused part or other vehicles, wherein passes through
Part, which refers to, to be mounted on vehicle body, in the part that experimental stage is not failed by test.In the embodiment of the present invention, to failure part
The contrasting detection of metallographic and hardness test has been carried out with unused part.
In other embodiments, if failure part processing and fabricating when be distinctly claimed, if dimensional discrepancy be less than national standard, it is right
When the part that fails carries out a certain detection project, the drawing requirement of part reference may also be made to.
According to the failure mode and comparing result of failure part, the failure cause of failure part is determined；
By comparing detection, testing result to failure part and unused part are as follows: disabling elements and unused part hardness
No significant difference, the metallographic no significant difference of core structure.But it is found in the metallographic structure of the cross section sample at turning
Have crackle, and crack length is more than 477um, and be not used part crack length be up to 377um, crackle occur position with open
It is consistent to split invalid position.Therefore failure cause sums up are as follows: in the fabrication process since bending technique introduces micro-flaw, causes the later period
Fatigue cracking failure during test.The judgement reason is identical as failure cause is estimated.
According to failure cause, change scheme is proposed to failure part；
Stress loading analysis is carried out to clip, obtains clip stress and little, but need 90-degree bent in the fabrication process, it is right
The formability of material itself is more demanding.This case that need 90-degree bent for clip, increases after bending technique and be ground together
Technique reduces stress and concentrates to remove the microscope crackle generated in manufacture.
Part after change is re-started into verification test.
If the part after change does not fail by verifying, illustrates that failure cause analysis is correct, change scheme has
Effect.Then, all material uploads of the clip failure analysis are referred into Materials failure analysis database in case inquiring.
If unverified test, failure analysis is carried out to failure part again according to above-mentioned steps, finds out failure
Reason, until through verification test.
More than, technical solution of the present invention is described in detail in conjunction with specific embodiments, described specific implementation
Example is used to help understand thought of the invention.The derivation that those skilled in the art make on the basis of the specific embodiment of the invention
It is also belonged within the scope of the present invention with modification.
