Abstract
In order to explore the intracranial pressure response under different sensor fixation modes, the experimental study on the pressure measurement based on physical head surrogate under shock wave is carried out. The influence of different sensor fixation methods on the intracranial pressure was analyzed. The results show that sensor fixation mode has little influence on the pressure test results. The deviation between the pressure peak and impulse is only 3.62% and 4.54% in the two modes of hot melt supporting and free suspension. The deviation of pressure peak value between metal supporting and free suspension is 5.59%. In comparison, hot melt supporting fixation has less influence on intracranial pressure results. The orientation of sensor sensitive surface has little influence on the pressure test results. When sensor was fixed by the metal bracket, the deviation of pressure peak is only 4.03% between sensitive surface face to impact source and sensitive surface back to shock source.
