Based on the inherent frequency of vibration monitor system consisting of sensor, mounting hous?ing and casing, analyses were presented from different boundary , structure sizes and mass. Comparison of effect results has been made to determine the numerical analysis method of vibration sensor mounting house. Using coin-tap method, test and response analysis of the inherent frequency for vibration monitor system have been carried out. The analytic method has been verified to be effective.
