The Characteristics of Low Frequency on Detecting Method via Strain Gages

Abstract:

In order to find out the feasibility to obtain dynamics peculiarity in high frequency domain, the dynamic peculiarity on detecting method with strain gages is researched. By modeling and analyzing qualitatively, the characteristics of low frequency are indicated for strain gages sensor system. Comparing with the test signal difference between vibration acceleration sensor and strain gages sensor system at the three domain which are time, amplitude and frequency, the characteristics of low frequency are proved for the one. Therefore while detecting the high frequency dynamic signal with strain gages sensor system, the high frequency information is attenuated, the mostly spectrum information is lost.
