A Study on the Estimation Method of Impact Position Using the Frequency Analysis

In this paper, we proposed a new algorithm that can be detected impact position on LPMS using the characteristic of RMS (root mean square) values and analysis of frequency. The proposed estimation algorithm of impact position uses the arriving difference time method using the analysis of frequency and the RMS value. The LPMS (loose parts monitoring system) are used for detecting and evaluating metallic loose parts in reactor systems. On experiment, we use the modeling steel drum instead of real reactor and 4 accelerometer sensors for acquiring the impact signal. And the computer is connected the accelerometer sensor input and used for monitoring and analyzing of impact signal with Lab-view and Matlab programs. It is efficiently used for reducing processing time and estimated impact position.
