Deteksi Kerusakan Plat Dengan Menggunakan Sinyal Suara

ABSTRACK
Structural Health Monitoring (SHM) is a process of identifying damage by Nondestructive
Evaluation (NDE). The method can be done by non-contact method. In this study a non-contact
method was proposed to monitor the spesimen by ultilizing the sound signal as an excitation.
This method has advantage becauseit is not costly toset-up testing.Excitation is given to
spesimen by the loudspeaker. The sound response on the spesimen is recorded through the
microphone. Recorded data in the form of time domain is transformed into a frequency domain
using FFT (Fast Fourier Transform) method. With the domain data frequency respone and data
excitation frequency can be processed into data FRF(Frequency Respone Function).FRF matrix
form is used to estimate the mode shape. The first Natural frequency of mode shape is transform
to detect the location of the damage. The study was performed on spesimen under normal and
damaged conditions. The result of the research on simulation and testing show that proposed
method can detect the location of the damage properly and accurately.
