Description
Technical field
The present invention relates to one, a kind of industry CT is to the test device of the power of test in unsticking gap and side
Method.
Background technology
The Specifeca tion speeification of industrial CT system includes: test specimen scope (diameter, highly, weight, equivalent steel thick etc.), detection
Time (scanning, reconstruction time) and picture quality (density resolution, spatial resolution, pseudomorphism etc.).Wherein picture quality is work
The core index of industry CT system.
The original intention of process industry CT is the defect in detection sample, and it is worth and lies also in it appeared that for other lossless inspections
The defect that the inspection of survey method be can not check or Detection results is the best.Due to the complexity of practical problem, the defect under various physical conditions
It is difficult to severe quantization describe.In practice, three aspects such as usual density resolution, spatial resolution, pseudomorphism characterize industry CT
Picture quality, not only operability is preferable, and can make for the performance of different CT systems the most objective, science and quantitatively
Comparison.Although these have passed through the most abstract concept obtained is not equal to the power of test of reality, or concrete defect chi
Very little, but have closely contact between them, can the power of test of reasonably response system, the judgement system being well recognized as
The standard of energy.
Performance test methods for aspects such as the density resolution of industry CT, spatial resolution, pseudomorphisms has been correlated with
National standard (sees adnexa " GBT 26593-2011 nondestructive detecting instrument industrial X-ray CT device performance method of testing ")
As technical support, and the detection method in unsticking gap there is no concrete national standard and open test method.
Summary of the invention
The purpose of the present invention, it is simply that for the deficiency existing for prior art, and provide a kind of industry CT to unsticking gap
The test device and method of power of test, the program uses and arranges scalable crack width, utilizes CT to observe, obtain CT instrument
The minimum crack distance being capable of identify that, so that it is determined that the unsticking gap detection ability of industry CT.
This programme is achieved by the following technical measures:
A kind of industry CT test device to the power of test in unsticking gap, includes steel plate, the first poly (methyl methacrylate) plate, second has
Machine glass plate and fixing bar；First poly (methyl methacrylate) plate and the second poly (methyl methacrylate) plate are fixed on steel plate by fixing bar；First has
The second crack is formed between machine glass plate and the second poly (methyl methacrylate) plate；The first folder is formed between first poly (methyl methacrylate) plate and steel plate
Seam.
Preferred as this programme: the gap of the first crack can regulate.
Preferred as this programme: the gap of the second crack is fixed.
A kind of industry CT method of testing to the power of test in unsticking gap, uses industry CT the to whole test device
One crack is irradiated, and regulates the gap of the first crack from small to large, until the minimum crack distance that CT system is capable of identify that is i.e.
Distance value for the unsticking gap detection ability of industry CT.
Preferred as this programme: the gap adjustment range of the first crack is 0.1-1mm.
Preferred as this programme: the clearance distance of the second crack is 0.1mm.
The beneficial effect of this programme can be learnt according to the narration of such scheme, due to use in this scenario arrange adjustable
Joint crack width, utilizes CT to observe, obtains the minimum crack distance that CT instrument is capable of identify that, so that it is determined that between the unsticking of industry CT
Gap power of test.
As can be seen here, the present invention compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented is also
It is apparent from.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure, 1 is steel plate, and 2 is the first poly (methyl methacrylate) plate, and 3 is the second poly (methyl methacrylate) plate, and 4 is the first crack, and 5 is second
Crack, 6 is fixing bar.
Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, except mutually exclusive
Feature and/or step beyond, all can combine by any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), unless chatted especially
State, all can be by other equivalences or there is the alternative features of similar purpose replaced.I.e., unless specifically stated otherwise, each feature is only
It it is an example in a series of equivalence or similar characteristics.
By accompanying drawing it can be seen that this programme includes steel plate, the first poly (methyl methacrylate) plate, the second poly (methyl methacrylate) plate and fixes
Bar；First poly (methyl methacrylate) plate and the second poly (methyl methacrylate) plate are fixed on steel plate by fixing bar；First poly (methyl methacrylate) plate and second
The second crack is formed between poly (methyl methacrylate) plate；The first crack is formed between first poly (methyl methacrylate) plate and steel plate.Between the first crack
Gap can regulate.The gap of the second crack is fixed.
The method of testing of employing said apparatus is: use industry CT to be irradiated the first crack of whole test device,
Regulate the gap of the first crack from small to large, until the minimum crack distance that CT system is capable of identify that is between the unsticking of industry CT
The distance value of gap power of test.
The gap adjustment range of the first crack is 0.1-1mm.
The clearance distance of the second crack is 0.1mm.
This programme simple in construction, easy to detect, it is possible to accurately measure the unsticking gap detection ability of industry CT, for work
The performance indications detection of industry CT has preferable effect.
The invention is not limited in aforesaid detailed description of the invention.The present invention expands to any disclose in this manual
New feature or any new combination, and the arbitrary new method that discloses or the step of process or any new combination.
