A New Dynamic Measuring Method of Young Modulus Based on Magnetics Coupling and Double Raster

Abstract:

In this article, a new dynamic measuring method of young modulus based on magnetics coupling and double raster has been thoroughly given. The test sampie has been thoroughly free oscillated so as to decreasing systematic error of normal experiment principle , by Electromagnetic energy uncontract coupling sample shake and by use of laser light beating to measuring micro shake. the schematic diagram and the measureing method of light beating micro shake has been given, so are computational formula of young modulus, experiment results, error analysis and results.
