KAJI BANDING HASIL PENGUKURAN FUNGSI RESPON FREKUENSI
MENGGUNAKAN PERANGKAT AKUISISI DATA MULTIPLEXING PCI-6281
DAN PERANGKAT AKUISISI DATA SEREMPAK MULTI KANAL MSA
HP3566A
Oleh:
Nama: William
NIM: 13103130
Pembimbing:
Prof. Dr. Ir. Komang Bagiasna
Ringkasan
Latar Belakang
- Laboratorium Dinamika ITB telah beberapa kali mengembangkan perangkat lunak
penganalisis sinyal getaran yang mampu melakukan pengukuran Fungsi Respon
Frekuensi (FRF) menggunakan perangkat akuisisi data multiplexing dan perangkat
akuisisi data serempak multi kanal.
- FRF merupakan fungsi perbandingan suatu respon dengan gaya eksitasi yang
dinyatakan dalam domain frekuensi. Baik respon dan getaran harus diukur dalam
waktu yang bersamaan.
Perumusan Masalah
Melaksanakan kaji banding hasil pengukuran FRF menggunakan perangkat akuisisi
data multiplexing PCI-6281 dan perangkat akuisisi data serempak multi kanal MSA
HP3566A.
Metode Penyelesaian Masalah
1. Studi literatur tentang perangkat lunak yang telah dikembangkan sebelumnya di
Laboratorium Dinamika ITB.
2. Studi literatur mengenai bahasa pemrograman LabVIEW 7.1 dan NI-DAQmx 7.4
beserta teori dan teknik akuisisi data.
3. Pembuatan perangkat lunak analisis FRF dengan kartu akuisisi data PCI-6281.
4. Validasi perangkat lunak yang telah dikembangkan.
5. Pengujian FRF pada struktur pelat T.
6. Pengujian FRF pada struktur batang tumpuan sederhana
7. Evaluasi data hasil pengujian yang telah dilakukan.
Hasil
- Pengembangan perangkat lunak untuk melakukan pengukuran FRF metode eksitasi
kejut dan metode swept sine dengan menggunakan kartu akuisisi data multiplexing
PCI-6281.
- Kegiatan kaji banding hasil pengukuran FRF tidak dapat dilakukan dengan
sempurna karena fasilitas filter yang terdapat di kartu PCI-6281 tidak dapat
berfungsi sebagai anti-aliasing filter yang benar.
