Description
Technical field
The utility model relates to a kind of macromolecular material of analyzing at a kind of device that moment is changed by the physical property that produces in the process of certain energy impact, especially researchs and analyses a kind of dynamic impulsion analyser that material is subjected to the change procedure of viscosity, elasticity, plasticity, embrittlement under certain energy impact effect.
Background technology
At present, known impact test method is the pendulum with known energy, and the energy that the one-shot sample measurement is absorbed when destroying is by the dial plate reading.But, this test method, personnel can only obtain a final impact energy values, can not write down the impulse test process of moment, can not obtain impulsive force, speed, ductility, dynamic toughness, fracture and these important informations of yield load numerical value.And its result is subjected to friction factor, artificial factor, causes that data are inaccurate, error is big, causes the profiling error to style.
Summary of the invention
The utility model provides a kind of dynamic impulsion analyser, to solve the problem that can only obtain a final impact energy values that present instrument exists.The technical scheme that the utility model is taked is: the adjustment screw is threaded below the frame, this adjustment screw is fixedlyed connected with cushion block, the level-off platform is fixedlyed connected with gantry base, the sample bearing is fixedlyed connected with gantry base, Sample carrier is fixedlyed connected with this sample bearing, limit base is fixedlyed connected with upper rack, spacing handle and limit base are rotationally connected, pendulum is connected with frame by swing arm, angular displacement sensor is fixedlyed connected with the pendulum axial region, force transducer is fixedlyed connected with pendulum, and limited block is fixedly connected in the swing arm.
The utility model advantage is: simple in structure, and processing ease, it is reliable to draw the analysis data.Viscosity, elasticity, plasticity, the embrittlement significant data that not only can provide in the experimentation to be taken place, but also can depict the impact process curve, can choose at any time on the curve more arbitrarily, section, amplify, to testing of materials and analysis.Also can be to the data-switching between international, U.S. mark, international standard.After the broken impact of sample, produce signal through soft supervisory system of high speed angular displacement and load detection system, again through amplifying, the laggard line data of machine high-speed sampling is handled as calculated, draw N-T and J-T curve, computing machine can be analyzed curve, just can obtain material and be subjected to characteristic under the external force effect, analyzes the viscosity, elasticity, plasticity, the embrittlement change procedure that draw material.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model acquisition system high speed acquisition angular displacement sensor and load sensor signal, and the curve map of making among the figure, ejects dialog box.
Fig. 3 is that the utility model destroys type analysis figure, C, destroys fully, and H, hinge destroy, P, partial destruction, and N, B do not have destruction.
Fig. 4 is the conditional curve and the energy trace figure of each test, and each trial curve has two, and one is conditional curve, and one is energy trace, and the user can be by time and the angle of correlation curve, the toughness of analysis of material and the impact-resistant load of correlation curve.
Embodiment
Tested sample is installed on the Sample carrier 6, pendulum 8 impact specimens with certain energy, by force transducer 7, simultaneously by detecting the signal that angular displacement sensor 10 produces, again through amplifying, change number signal into by quick biography of microprocessor, give computing machine by the USB mouth and carry out the quantity processing, be used to draw the curve map of impact process.
