The utility model discloses fix the attenuator in torque sensor, detect out through torque sensor when changing the moment of torsion and turned angle of attenuator, the moment of torsion data of corresponding dynamics, through the dynamics change curve of processing unit with moment of torsion data conversion damping force, the rethread output unit printout or save to in production, can find out the damping that the dynamics matches according to the curve chart and glue, make the product obtain anticipated damping effect.
Description
Technical field
The utility model relates to a kind of proving installation, particularly a kind of damper hysteresis curve tester.
Background technology
In production fields such as auto industry, the damping force size of damper is decided by damping glue, aborning, the different needed damping forces of product are also different, usually be difficult to find actual providing and the identical damping glue of damping force dynamics that needs to produce, can only adopt the much the same damping glue of dynamics of demarcation.Will cause damping force so is not to be exactly greatly little, makes the product of production can not reach the damping of expection.
The utility model content
The utility model has overcome above-mentioned shortcoming, and a kind of damper hysteresis curve tester simple in structure, easy to use is provided.
The technical scheme in the invention for solving the technical problem is: a kind of damper hysteresis curve tester, comprise test table, comprise torque sensor, angular transducer, motor and chucking device in the described test table, also comprise successively the data acquisition unit, data processing unit and the output unit that connect, the output terminal of described torque sensor and angular transducer respectively with the input end of described data acquisition unit.
Described data processing unit also can be connected with a driver simultaneously, by described driver and control the running of described motor.
Described data acquisition unit can adopt the multi-channel data acquisition card.
Described data processing unit can be industrial computer or computing machine.
Described output unit can be printer.
Described output unit can be storer.
Described test table can be a plurality of, and links to each other with data processing unit with described data acquisition unit respectively.
The utility model is fixed on damper in the torque sensor, detect when moment of torsion that changes damper and the rotational angle by torque sensor, the moment of torsion data of corresponding dynamics, treated unit is with the dynamics change curve of moment of torsion data conversion damping force, again by described output unit printout or store, thereby aborning, can find out the damping glue of dynamics coupling, make product obtain the damping of expection according to curve map.
Description of drawings
Fig. 1 is the structural representation of test table in the utility model;
Fig. 2 is control principle figure of the present utility model;
Fig. 3 is a test process process flow diagram of the present utility model.
Embodiment
The utility model mainly is made of test table, multi-channel data acquisition card, computing machine and printer.Wherein said test table adopts the existing platform that is exclusively used in test damper moment of torsion, its structure as shown in fig. 1, mainly comprise by torque sensor 1, angular transducer 2, clamping frock 3 and stepper motor 4, tested damper 7 is installed in the described frock 3, described motor 4 rotates under the driving of driver 6, and drives the axle rotation that is connected with clamping frock 3 by belt 5.
Said structure based on test table, control principle of the present utility model as shown in Figure 2, by data collecting card is that the discernible digital signal of computing machine sends in the computing machine with the analog signal conversion of torque sensor 1 and angular transducer 2 collections respectively, by Computer Analysis angle, moment of torsion data, show output according to the mode of appointment.Detect the moment of torsion of total system coupling when damper 7 is driven rotation generation damping by motor 4 and the relation between the corner by torque sensor 1 and angular transducer 2, treated unit is that the hysteresis of damper system is returned and let out curve with moment of torsion and corner data conversion, by the operator with machine operation or pass through the printer output that connected automatically.
Like this, in actual production process, can find out the best damping glue of dynamics coupling, make product obtain the damping of expection, can not produce the excessive or too small situation of damping force according to the hysteresis curve synoptic diagram of the damper of drawing.
Each test table can be tested two parameters of the anglec of rotation, moment of torsion of a damper, is both the needs that many groups are measured for satisfying, and system uses the above data collecting card of 8 passages.Simultaneously a plurality of test tables are tested simultaneously, accurately controlled test process for making computing machine, that also need use motor in the driver control test table opens/stops process.
Test process of the present utility model as shown in Figure 3, described computer system is after also starting through initialization, control described motor rotation, in the process of running, constantly detect windup-degree and whether reach 180 degree by angular transducer, if do not reach then acquisition angles and torque value and control motor and be rotated further, reach 180 degree until windup-degree, after then testing result being preserved, prepare next time or the test of next damper.
In addition, the hysteresis curve that described computing machine obtains as calculated is stored in another storer, by using the damping glue of different brands, different lot numbers in repeatedly testing, correspondence is drawn out many hysteresis curves, also all be stored in the storer, set up the database of a hysteresis curve, use for type selecting in the production run.
More than damper hysteresis curve tester provided by the utility model is described in detail, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
