The course of work of the present utility model and principle:
Standard transducer instrument and tested sensor apparatus, its communication interface will match by the interface corresponding with computing machine, standard transducer instrument to collect also shows the data that standard transducer spreads out of, the stressing conditions of reflection standard transducer, standard transducer instrument by the data importing computing machine of standard transducer, for computer software acquisition process; Tested sensor apparatus gathers the data that tested sensor spreads out of, and reflects the stressing conditions of tested sensor.Tested sensor apparatus is by the data importing computing machine of tested sensor, and for computer software acquisition process, by running control program, collection comprises standard transducer instrument and tested sensor apparatus data, controls motor action operation, realizes full closed loop control.Printer is power machine test data print out equipment.The instruction of servomotor receiving computer, carries out accelerating, slows down, stops, rotating forward, the action such as reversion, and drive deceleration mechanism, makes beam lifting move.
During use, standard transducer is fixed on below dynamic crossbeam.Tested sensor is put on the test platform of upper part of the frame.After placement completes, tested sensor signal lines is connected to tested sensor apparatus by operating personnel, enables tested sensor apparatus normally show tested sensing data.After placement completes, generally make the gap retaining 2-5mm between standard transducer and tested sensor.This gap is the idle motion before power machine loads, and is also the idle motion after the unloading of power machine.The large I of this gap decides according to the system resilience of standard transducer, tested sensor, power machine mechanical framework, picks and places as principle decides to facilitate tested sensor.
Dynamic crossbeam is done to decline and is run, and the upper and lower space of framework be made up of dynamic crossbeam, leading screw, support is diminished, and applies pressure to standard transducer and tested sensor.Through one section of idle motion, start to load when standard transducer and tested sensor contacts, motor remains in operation and namely continues to load, until the stress value of standard transducer reaches the requirement of program setting.Dynamic crossbeam is done to rise and is run, and namely realizes standard transducer and the unloading of tested sensor.When standard transducer and tested sensor depart from, namely complete unloading.This rear motor also will continue to run, and makes to produce a gap between standard transducer and tested sensor, to facilitate tested sensor to pick and place, then shuts down.
Dynamic crossbeam oscilaltion campaign can be divided into operation automatically and manually run two kinds of forms, is controlled by computing machine.Automatic operation carries out in test run process, automatically controlled the states such as its lifting, speed, start and stop by software.Manual operation is when the unloaded grand movement of dynamic crossbeam, by software control, according to manual operation software, sends the actions such as operating instruction carries out being elevated, start and stop.
Specific works process is:
Operator runs relevant information by computer interface Input Forces machine: force value standard value, Detection of content require, various operational factor.Force value standard value is the standard transducer instrument indication value of the standard transducer by transmitting and verifying at each force value point, and force value standard value is the reference standard that power machine controls each force value point in operational process.
It is according to the requirement of tested sensor test content that Detection of content requires, may comprise or several in prestrain, non-linear test, creep test, sensitivity test.Operator places tested sensor, and connects tested sensor signal lines to tested sensor apparatus, confirms that power machine equipment is in normal Standby state.
Operator sends by computing machine the instruction that brings into operation, and namely power machine equipment starts to require to carry out testing according to the Detection of content of setting automatically.In power machine loading procedure, the target force values that computing machine requires in requiring according to Detection of content, reads force value standard value, with this force value standard value for desired value, calculates the gap between desired value and Current standards sensor apparatus indicating value, controls motor speed.When standard transducer instrument indication value is close to desired value, control decelerating through motor, difference between the force value utilizing mechnical servo On Fluctuations Cont rol Method of Precise Force value trace technical controlling power machine to apply and desired value is within the scope of national standard precision prescribed, and after force value stabilization, the tested sensor apparatus indicating value of computer acquisition, as the force value data of tested sensor.After power machine completes the Detection of content of Detection of content requirement defined, power machine unload, and run motor meet idle motion require after shut down.The tested sensor force Value Data of computer coordinates, calculates the indices of tested sensor, preserves data to hard disk, display data in screen, printout in printer.Namely a test assignment is completed.
