Simulasi Elemen Hingga untuk Tali Baja di Bawah Pengaruh Pembengkokan Paksa

Abstract

Tali baja secara luas digunakan dalam berbagai aplikasi. Pada kasus tertentu, tali baja dapat digunakan dengan cara dililitkan pada objek sehingga dipaksa bekerja di bawah pengaruh pembengkokan paksa. Det Norske Veritas (DNV) yang merupakan sebuah institusi sertifikasi independen, memberikan formulasi untuk menghitung pengurangan kapasitas tali baja berdasarkan rasio diameter pembengkokan dan diameter tali baja, D/d. Pengurangan kapasitas dalam hal ini adalah rasio terhadap kapasitas normal tali baja dalam kondisi aksial tarik. Penelitian ini dilakukan untuk mengetahui korelasi antara kondisi pembengkokan paksa dengan pengurangan kapasitas tali baja, mengetahui selisih antara hasil simulasi dengan formulasi DNV, serta mengetahui parameter yang berkontribusi terhadap pengurangan kapasitas tali baja. Penelitian dilakukan dengan metode simulasi elemen hingga. Dimulai dengan pemodelan kasus aksial tarik dengan variasi sudut lilitan, dilanjutkan dengan validasi terhadap hasil eksperimen dari literatur. Model dengan error minimum selanjutnya digunakan dalam simulasi pembengkokan paksa. Pengurangan kapasitas tali baja yang terjadi dibandingkan dengan hasil formulasi DNV. Hasil penelitian menunjukan semakin kecil nilai D/d pengurangan kapasitas yang terjadi semakin besar. Perbandingan dengan formulasi DNV menunjukan kesesuaian yang baik pada nilai D/d yang besar tetapi menurun pada nilai D/d yang semakin kecil dimana selisih yang dihasilkan semakin meningkat. Hasil simulasi juga menunjukan bahwa kekakuan material sangat mempengaruhi pengurangan kapasitas tali baja di bawah pengaruh pembengkokan paksa.
