The aim of this study has been to develop a measurement method to study the absorption of vibration energy on exposure to high frequency vibrations. The developed measurement method consists of specially constructed equipment for measurement and analysis of the subject's absorption of vibration energy. In this study the energy absorption from the exposure to white noise vibration within the frequency-range 20 to 5000 Hz has been studied. Five female and five male subjects were involved in this study. The results show that the developed method of measurement works satisfactorily and gives reliable results for the energy absorption within the frequency-range 20 to 4000 Hz. Furthermore, the results show that the subjects absorb vibration energy even for frequencies above 1000 Hz. The results also show that the energy absorption is dependent upon factors such as gender, the level of the vibration and the frequency.

Optimum Threshold

We make some investigations regarding the anomalous energy absorption in a turbulent plasma through high-frequency parametric instabilities. We establish the optimum threshold conditions with respect to the pump frequency. The influence of the turbulence spectrum on the parametric phenomena is investigated.

This work studied the cushion efficiencies of aluminum foam and metal rubber as the cushion materials for microaccelerometers under shock load. A series of shock experiments were carried out to test the performance of these two materials. Preliminary results indicated that aluminum foam and metal rubber have different energy absorption mechanisms, and both of them have excellent energy absorption capability, which can effectively cushion the effect of shocking pulse peak and suppress the high-frequency vibration noise. Aluminum foam and metal rubber are believed to be promising cushion materials for microaccelerometer.
