Product Description

Product Description

DTM-I dynamic elastic modulus tester Elastic Modulus Testing Apparatus Young's elastic modulus machine price
1.Product introductionFor certain objects, there is a natural resonance frequency. When the volume and material of an object are constant, the resonant frequency of the object is only related to its density. The strength of an object is related to its density, so the natural vibration frequency of the object determines the object's strength. If the resonant frequency of the object can be measured, the strength of the object can be calculated based on strength theory. This instrument is an instrument that measures the resonant frequency of an object and calculates the elastic modulus, shear modulus, and Poisson's ratio of the object. It can measure ceramics, graphite, glass, plastic, metal materials, etc. It is widely used in various production enterprises, scientific research units, colleges and universities, quality inspection departments, etc. Instrument reference standards: GB5594.2, GB/T 3074.2, GB/T3074.2-2008 "Measurement method of elastic modulus of graphite electrodes" GB/T5594 Young's elastic modulus Poisson's ratio test method and GB/T 2105, GB10700, etc. .

This instrument adopts imported data acquisition control card and uses computer control to realize the automation of the whole process of testing, calculation and reporting.

3. Working principle
      The computer-controlled data acquisition control card outputs a sine wave signal with a frequency ranging from small to large to the transmitting probe. The oscillation of the transmitting probe is transmitted to the specimen, forcing the specimen to mechanically vibrate. When the transmitting frequency is the same as the natural frequency of the specimen, resonance will occur. , at this time, the vibration amplitude of the specimen will produce an extreme value, which is transmitted to the data acquisition control card through the receiving sensor probe and then transmitted back to the computer. The computer scans according to the frequency to find the resonant frequency, and then based on the weight and dimensions of the specimen input to the computer The elastic modulus, shear modulus and Poisson's ratio are calculated.
