| Abstract: | This paper performs the modal analysis for HDD HGA,and the principle of resonance test for HGA with laser Doppler technique is presented.Based on this principle,a novel laser Doppler measurement system is formed to detect resonant characteristic of HGA.Used this system,the results of resonance test is obtained with three varieties HGA.The experiments prove that the system can effectively be used to measure resonant characteristic,which can arrive at a high accuracy. |
