Research And Implementation Of A Comprehensive Test Control System For Metal Creep Test

With the rapid development of national defense industry,power industry,needs a large number of metal components in high temperature and high pressure and corrosive medium under the conditions of service.Once the bearing metal member is accidental damage will lead to serious or even catastrophic consequences,and will cause huge economic losses to the user.Therefore,the safety and reliability of metal materials are more and more stringent.Because many metal components will be subjected to high temperature and high pressure for a long time,these metal bearing components will face a special challenge,namely high temperature creep.For long-term work under high temperature and high pressure condition of metal components,the service life of the creep behavior of these metal component and its safety and reliability influence is very large,and even decisive role.Due to the microstructure,chemical composition and thermo physical properties of different metal materials are different or even quite different.Therefore,the creep properties of different metal materials are also different.Therefore,in the industrial production,it is necessary to get the creep property and service life of the metal material in advance by the test.At present,many research institutes and enterprises are engaged in metal experimental research,such as the Creep Laboratory of Metal Research Institute,which is committed to the research of metal test all the year round.With the rapid development of computer technology,more and more industrial production is combined with computer technology,and the application of computer technology can help to improve the efficiency and accuracy of operation.In the process of metal experimental study,the addition of computer software is also very necessary,through the computer software for users to provide accurate and reliable support can greatly improve the efficiency and accuracy of metal test.Therefore,it is very important to develop an upper computer software which can monitor and analyze the high temperature creep property of metal materials.Aiming at the defects and problems existing in the control system of creep persistent comprehensive test,this paper studies and develops the control system software suitable for the creep and endurance test.The main research and implementation are as follows:1.Research on standards and methods for comprehensive metal creep tests.2.Automatically establish communication with the underlying controller through the network port.3.Strict control of the test procedure through parameter settings.4.Real-time data monitoring and acquisition,storage and complete presentation of various test information.5.The test process interrupts the good handling of electrical recovery and offline recovery.6.The real-time curve and historical curve of the data during the test.7.Data processing and conclusion analysis of relevant test data.
