Abstract: An automatic measure instrument for Young's modulus by a method in dynamic state is introduced. The Young's modulus automatically on the base of its adoption of sweep measurement technology is measured and computed by using this instrument. It can also adjust the false resonance and supply the quality factor, which is of great help for improving the accuracy of the results.

Key words: Young's modulus, measurement instrument, automatic frequency sweep, quality factor
