Description
[technical field]
The present invention relates to the material testing machine observe and control system technical field, specifically, is a kind of high-precision electronic formula contact engaging and separating force test macro.
[background technology]
Along with commercial production and science and technology development, testing machine manufacturing industry has also had very fast progress.Various new materials emerges in large numbers since particularly World War II finishes, in especially nearly two, 30 years, developing rapidly of Aero-Space cause and microelectric technique, computer science and closed loop automatic control engineering excited the speed of development of testing machine and experimental technique widely.
Deepen continuously along with international, test method and testing machine all need meet international standard, and testing machine also will adapt to the requirement of international standard and develop.Along with the continuous innovation of technology, test need develop to high precision int, robotization, systematization, microminiaturization, compoundization direction simultaneously.
The development trend of hyundai electronics contact engaging and separating force testing machine is embodied in the following aspects:
(1) computerize
Computing machine is 1950's computer technology develop rapidly over more than 50 year to occur.The characteristics of computing machine are: (1) fast operation, and modern high performance computing machine top speed can be carried out 1,000,000,000 computings p.s.; (2) energy stored data and program promptly have the function of memory; (3) have the logic determines ability, can compare two information; (4) have very high precision and reliability.Increase output economizes in raw materials and the important tool of manpower because above characteristics, computing machine are not only, and also is to improve production technology, improves the indispensable instrument of the efficiency of management.
Because popularizing of the raising of computer technology and microcomputer, many new material testing machines have been realized computerize.The introducing of computing machine is accurately handled data and the control robotization becomes possibility.For example Tianjin, island AG-A, AG-E, AG-S type series, this testing machine is in each stage of test, controls to the data processing robotization that all relied on computer realization from load metering, testing machine, saved the adjusting time.
In addition, along with popularizing of micro-processor controlled Material Testing Machine, programming system has also obtained constantly enriching and is perfect, and the effect of test method standardization has also obtained admitting.Except that tension test, the standardization of test methods such as destructive test, low cycle facigue test, impact test, bending test is also adopted, and is compiled in the program input computing machine, so that in time access use when needing.
(2) robotization, systematization
The robotization of Material Testing Machine, easy are exactly the target that people pursued for a long time.Finished the full-automatic tensioning system of metal before more than ten years.Print is placed on the correct position of grip of testing machine by mechanical arm, under test condition, can measures its variation then by apparatus for automatically measuring.When test stopped, it can change next print automatically, till off-test.As long as necessary test figure clicks button, just can automatically handle, this existing data processing function of processor by microcomputor program control has writing function again, in addition, can also draw load-displacement curves, also can print required result in case of necessity.
Starting late of domestic contact engaging and separating force testing machine TT﹠C system, technical reserve and synthetic study level lag far behind.Therefore make full use of the achievement in research of present age computer technology, especially Computer Control Technology, the computer control fatigue rig is made in development, meets international testing machine research and development direction.The various Material Testing Machine of market sale at home and abroad at present also are of a great variety, Market Situation becomes the gold tower to distribute, basic condition all is that famous big companies such as American I nstron, Japanese AIKOH, day island proper Tianjin occupy high-end market, their product maturation, stable, precision is high, cost an arm and a leg.Taiwan is along crystal-clear and domesticly think carefully newly etc. that general 4-5 family has the company of certain strength to occupy market, middle reaches, middle reaches product stability, precision etc. can both meet the demands, price is also more expensive, also have general ten tame enterprises to occupy low-end market, the product sales volume is big, application industry is extensive, and dragons and fishes jumbled together for product quality, but cheap.
Because there are many shortcomings as above in domestic contact engaging and separating force testing machine, external contact engaging and separating force testing machine costs an arm and a leg, therefore develop a kind of advanced person's contact engaging and separating force testing machine TT﹠C system with actual application value, for the accuracy of reliable and stable the carrying out of guaranteeing material test and test figure thereof, the generation of avoiding fault, minimizing manpower financial capacity's huge waste, the application and the development that promote China's contact engaging and separating force testing machine have crucial meaning.
In contact engaging and separating force test macro field, legacy test system is mechanical type and electronic type.Mechanical type contact engaging and separating force test macro mainly designs and is mechanical mechanism, driving physical construction by drive unit moves reciprocatingly, function aspects can only simply realize the to-and-fro movement counting, traditional mechanical formula contact engaging and separating force test macro is mainly used in the plug procedure parameter be need not to understand, and with the test case of the qualified number of times of finishing plug of plug part as the whether qualified parameter of plug part; Traditional electrical minor contact engaging and separating force test macro adopts single-chip microcomputer as control system usually, application is used for some simple relatively, the less test sites of data volume, powerful relatively in functional requirement, control is complicated, and the huge relatively test site employing of data volume is satisfied corresponding requirement in embedded system.
Because the limitation of traditional contact engaging and separating force test macro needs exploitation to be fit to the modern contact engaging and separating force test macro that requires.Because novel test macro requires to have the powerful data analysis ability, good man machine operation interface, good generation form ability, these require for adopting traditional embedded being difficult to realize, novel contact engaging and separating force test macro makes up novel contact engaging and separating force test macro with way of hardware and software combination.Testing software adopts Labview exploitation host computer testing software, and the patterned programmed environment of Labview is convenient to quick development and testing application program, and Labview also makes developing application convenient more at the Test Application characteristics of development.Labview supports the communication protocol of the overwhelming majority, development and testing application program like this can communicate with hardware device easily, Labview provides huge data processing function node simultaneously, so just can satisfy the requirement of novel contact engaging and separating force test macro to data analysis function.
