| Outline For certain objects, there is a natural resonance frequency. When the volume of the object, the material must, the object resonance frequency is only related to its density. The intensity of the object to its density, and therefore the natural vibration frequency of the object determines the intensity of object.Able to measure the resonant frequency of the object, it can be deduced according to the strength theory the strength of the object. The instrument is measuring the resonant frequency of the object object calculated elastic modulus, shear modulus, Poisson's ratio instrument. Of ceramics, graphite, glass, plastic, metal materials, etc. can be measured. Widely used in the production enterprises, research institutes, universities, quality inspection departments. The instrument reference standard: GB5594.2 GB / T 3074.2, GB/T3074.2-2008 elastic modulus graphite electrode measuring method "GB/T5594 Young's modulus of elasticity Poisson's ratio test method GB / T 2105, GB10700 etc. . This instrument uses imported data acquisition and control card, using computer control to achieve test calculation, the statements of the whole process automation. DTM-II Dynamic method elastic modulus tester main technical indicators Frequency measuring range: 100Hz ~ 50 kHz Frequency resolution: 0.1Hz Measurement error: <0.5% Sample temperature: room temperature 0-9 --- 1000, 0 -13,500 0-1650, by user selectable Environmental conditions: 0 to 40 ºC, relative humidity less than 90%. Power supply: AC220V ± 10% of, 50Hz. DTM-II Dynamic elastic modulus by tester works The output frequency of the control card of computer controlled data acquisition from small to large sine wave signal to the transmission probe, the emission of the probe oscillation is passed to the sample forcing the specimen to conduct the mechanical vibration, resonance will occur when the natural frequency of the transmission frequency and the test piece with the same In this case, the vibration amplitude of the specimen will generate extreme values, data acquisition and control card by receiving sensor probe passed to send it back to the computer, the computer based on frequency scanning to find the resonance frequency, according to the input to the sample weight and dimensions of the computer calculate the elastic modulus, shear modulus and Poisson's ratio. |
