The wear life real-time prediction device comprises: a real-time monitoring system and a computer, wherein the real-time monitoring system comprises a scanning electron microscope, a wear testing machine and a profile analyzer.
Description
Technical field
The utility model relates to a kind of wear-out life real-time estimate device, can the on-line prediction engineering goods wear out failure time, help the designer to predict fault early, for product complete period Life Design provides effective ways and means, belong to the machine reliability design analysis technical field.
Background technology
According to statistics, in military hardware, what the form of expression of damage of components was the most outstanding is wearing and tearing.According to the investigation of U.S. army side, the most of U.S. army equipment that uses in the war in Iraq successively heavy wear occurs, and U.S. army once required to appropriate funds 9,000,000,000 dollars, to repair these badly damaged weapons.The engine failure of China's heavy weight fighter statistics is shown have 88% to be caused by friction problem in 17 accidents, cause that flame-out in flight, engine are damaged, rotor off-axis even fatal crass's serious consequence; The present part intermediate range of the typing bullet engine that cruises, because friction problem, the actual examination life-span has only 1/5～1/3 of designed life, and the life-span distributes serious discrete.
The integrity problem of tribology has become the technical bottleneck of the great model of part and defence equipment, existing great model is also all in the counterplan of seeking to rise substitution effect, to improve the reliability of system, therefore, the integrity problem of tribology has become out-and-out key technical problem.The focusing on of tribology research economizes on resources, the serviceable life of prolonged mechanical equipment, thereby improves reliability of products.But the life-span of prolongation is limited, and for engineering goods, particularly Large-size Arms and Equipments all must be faced with maintenance; So, " how to go to improve the wear-resistant reliability of product from the reliability angle ", " how going to estimate resistance to wearing the life-span of product ", " how many confidence levels of predicted life value is ", " when should keep in repair equipment " wait these a series of problems still to exist.For addressing these problems, we are badly in need of a cover technology can predict its Q-percentile life more exactly.
The key of the real-time life prediction problem of wearing and tearing is the on-line monitoring of wear extent, and the method for abrasion amount measuring comprises at present: weight method, measurement wearing and tearing spot diameter method, wearing depth measurement etc.Weight method is to use abrasion amount measuring method the most widely, and precision depends primarily on the instrument of measurement, in addition, and the influence of weather conditions, external environment condition, and the enchancement factors such as oxidation of test specimen all can exert an influence to measuring accuracy in the experimental measurement process.More crucial is that weight method needs abort, and when testing again, the fixed position of test specimen etc. all can exert an influence to the continuity of test.Therefore, real-time online measuring is particularly important, and the utility model provides a cover wear-out life real-time estimate device, can detect wear extent.
Summary of the invention
In order to solve wear extent on-line measurement difficulty, inaccurate, the difficult problem of life prediction of precision, the utility model makes up a kind of wear-out life real-time estimate device, can the on-line monitoring wear extent, help the designer to predict fault early, wear-out life real-time estimate device of the present invention comprises: real-time monitoring system and computing machine, wherein real-time monitoring system comprises scanning electron microscope, abrasion tester and profile analysis instrument.
The present utility model solves the technical scheme that its technical matters adopts: a kind of wear-out life real-time estimate device is provided, comprise: real-time monitoring system and computing machine, wherein real-time monitoring system is by scanning electron microscope, abrasion tester and profile analysis instrument three parts are formed, described abrasion tester comprises lower main axis, drive system, the hydraulic pressure force application system, friction pair and electric control box, described scanning electron microscope is installed on the abrasion tester support, near friction pair, described scanning electron microscope can be rotated by 360 degree, described profile analysis instrument is installed in the right side of scanning electron microscope, be fixed on the described abrasion tester support, the three-dimensional appearance that scanning electron microscope scanning obtains is sent to the profile analysis instrument, the profile analysis instrument is sent to electric control box to the information that described three-dimensional appearance will extract behind the profile information after will extracting by cable, and electric control box is connected with computing machine by serial interface cable.Principle according to scanning electron microscope is made scanning lens, is installed on the abrasion tester, sets and tests detection time, and test stops, and need not to take off test specimen, i.e. the 3 d surface topography of available scanning lens scanning test specimen; By the profile analysis instrument, can extract profile information fast and accurately, computing machine carries out feature extraction to three-dimensional appearance automatically, calculates wear extent, reaches the purpose of online real-time estimate.
Beneficial effect of the present utility model is, can online real-time estimate wear-out life, play forewarning function.Adopt the three-dimensional surface shape of scanning electron microscope real time scan friction pair, can the real-time online measuring wear extent, thus effectively predict the wear out failure time, the means direct convenience, precision of prediction is accurate.
