Referring to Fig. 6, the utility model utilizes the structure of all-in-one (with the integral industrial control computing machine of touch-screen) 20, the conglomerate 10 of proportion electro-magnet and spring ability meter mechanical part is arranged on to all-in-one 20 bottoms puts down forward on the worktable of stretching, mounting base and the action button of carrying physical construction conglomerate are fixed on the front console of all-in-one, and described automatically controlled test macro cell arrangement is arranged in the vertical electric gas holder of all-in-one 20.Also can be automatically controlled test macro cell arrangement and arrange USB interface, printing interface and network interface, more function is provided.Meanwhile, what automatically controlled test macro cell arrangement can also be real-time by the software systems that are equipped with records test figure, and rendering performance curve is also presented on touch-screen.
Principle of work of the present utility model is:
(1) electromagnet power output---placement property: the fixed current of magnet coil remaining unchanged of flowing through, measure the relation between its power output and stroke.In electromagnet travel range, to be less than the speed circulation (being conventionally not more than 0.05Hz) that testing apparatus dynamic perfromance works, do the continuous curve of a complete cycle with positive revesal, this curve is power---displacement curve.If change electric current, can obtain the one group of family of curves (referring to Fig. 7) under different electric currents just repeat above-mentioned test, Zhe Zu family of curves just complete representation electromagnet power output---placement property.The middle locus of points of curve adopted power output---stroke (displacement) family curve of running after fame.
Test mode: according to the model of tested proportion electro-magnet and size Selection supporting test fixture with it, be arranged on mounting base, and fix by fixture.The extension bar of proportion electro-magnet is corresponding with the gauge head of power sensor, the power output of detection ratio electromagnet in realizing displacement.Displacement transducer gauge head and power sensor are rigidly connected, indirectly the displacement of measurement scale electromagnet take-off lever.Realize all-in-one and electronic control translation stage controller, programmable DC linear power supply independent serial communication separately by programming, control, monitoring electronic control translation stage and programmable DC linear power supply.All-in-one sends command signal to programmable DC linear power supply, makes a fixed current of power supply output drive ratio magnet coil.Meanwhile, all-in-one sends command signal to electronic control translation stage controller, makes electronic control translation stage according to speed and the stroke reciprocating (being less than 0.05Hz) set.Now gather force sensor signals and displacement transducer signal by data collecting card, be uploaded to after all-in-one, by program, gathered signal is processed, real-time drafting is take shift value as horizontal ordinate, a power output---the displacement curve that power value is ordinate.The output current that changes programmable DC linear power supply can obtain gang's power output---displacement curve, has described power output---the placement property of tested proportion electro-magnet completely.Family of curves is demonstration in real time on all-in-one touch-screen, can be by the data that gather with EXCEL form by all-in-one, and the curve of drafting is preserved with JPG form.Proving installation is furnished with USB interface, printing interface and network interface.Can be by different modes by data conversion storage or output.
(2) electromagnet power output---current characteristics: conventionally electromagnet core is fixed on to some positions, it is generally the mid point of nominal operation stroke, then change input control electric current and obtain corresponding power output, the speed circulation (being conventionally not more than 0.05Hz) of working to be less than testing apparatus dynamic perfromance within the scope of rated current, change a complete cycle of size of current work with positive and negative two directions and obtain continuous curve, this curve is power output---current characteristics curve.The middle locus of points of curve adopted power output---the current characteristics curve of running after fame
Method of testing: all-in-one sends command signal to electronic control translation stage controller, makes electronic control translation stage drive sensor promotion proportion electro-magnet take-off lever be parked in a certain position of perform region.Meanwhile, all-in-one sends command signal to programmable DC linear power supply, and power supply is exported take zero as starting point, and the electric current of the ramp function that amplitude is 0-3A drives ratio magnet coil.Now, the power output of proportion electro-magnet changes with the variation of electric current, and push rod displacement remains unchanged under the location of electronic control translation stage.Now gather force sensor signals by data collecting card, record the output current signal of programmable DC linear power supply simultaneously.Be uploaded to after all-in-one, by program, gathered signal processed, real-time drafting is take digit current as horizontal ordinate, the electric current that power value is ordinate---output force characteristics curve (referring to Fig. 8).
(3) spring power output---current characteristics: rigidly connect while touching and start to continue spring to exert pressure from power sensor and spring, reduce gradually pressure after being pressed onto certain degree, until power sensor separates with spring.Power output---the displacement curve that the curve that the record shift value corresponding with pressure done is spring.
Method of testing: proportion electro-magnet sectional fixture is pulled down, spring perch is arranged on the fixed mesa of proportion electro-magnet spring tester.Electronic control translation stage is moved to and loads the position of distal-most end, by tested spring fitting on fixture.All-in-one control electronic control translation stage, according to the speed uniform motion of setting, compresses tested spring simultaneously, and displacement transducer detects the displacement of electronic control translation stage, the force of compression of power sensor detection springs.The signal that sensor collects flows to all-in-one by data collecting card, by program, gathered signal is processed, and real-time drafting is take Bit Shift as horizontal ordinate, the displacement that power value is ordinate---spring force family curve (referring to Fig. 9).
The various embodiments described above can not depart from some variations in addition under scope of the present utility model, thus above explanation comprise should be considered as exemplary, but not the protection domain of applying for a patent in order to limit the utility model.
