Abstract
The utility model relates to a damage tolerance test crack detection device used for fatigue tests. The detection device includes a control computer, and a digital camera arranged on a test bed and accommodating a test piece in a framing zone of the digital camera, wherein the digital camera is connected with a control computer. The utility model has the advantages and the benefits that the detection device can send trigger signals according to the test loading time or send trigger signals according to the test loading value, record the crack propagation situation of the test piece, store crack photos easily, and facilitate crack propagation situation analysis, thereby reducing the work load of a tester and avoiding defects that the ocular estimate has low precision, the test is disturbed easily, and the tester is fatigable.
Description
Technical field
The utility model relates to a kind of a kind of damage tolerance test crack detection device that is used for torture test.
Background technology
At present, fatigue criterion pilot system system in process of the test can't write down the testpieces crackle automatically both at home and abroad, need testing crew to adopt ocular estimate manual record crack propagation situation, it is bigger that there is the measuring intervals of TIME out of true in manual record, measuring accuracy is low, measurement result is influenced by record's individual difference, and the more high shortcoming of cost of labor.
Summary of the invention
The purpose of this utility model provides a kind of a kind of damage tolerance test crack detection device that can write down crack extending length automatically.Technical solution of the present utility model is, pick-up unit comprises control computer, digital camera, and digital camera places on the testing table and testpieces placed in the view area of digital camera, and digital camera and control computer are joined.Advantage that the utlity model has and beneficial effect, the utility model can load number of times according to test and send trigger pip, or send trigger pip according to the test load value, and testpieces is carried out crack propagation situation record, the crackle photo is preserved easily and is also conveniently carried out the crack propagation situation analysis.Reduced the testing crew workload, avoided the ocular estimate precision low, be subject to disturb, the fatigable shortcoming of survey crew.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.Pick-up unit comprises control computer 1, digital camera 3, and digital camera 3 places on the testing table and testpieces 4 placed in the view area of digital camera 3, and digital camera 3 joins with control computer 1.
Annexation of the present utility model
System mainly is made up of universal test bench, hydraulic system and control system.
Operating process of the present utility model
Automatically the record crack propagation has two kinds of triggering modes:
● the test run number of times that every interval is predetermined, control computer 1 triggers lead 2 by digital camera and triggers digital camera 3 automatic cameras 1 time, the crackle 5 of record testpieces 4;
● whenever reach predetermined test load bid value, control computer 1 triggers lead 2 by digital camera and triggers digital camera 3 automatic cameras 1 time, the crackle 5 of record testpieces 4.
