Abstract

Penelitian ini bertujuan untuk mengoptimasi model panel sandwich U-Beam Corrugated Core sebagai struktur geladak kapal, serta membandingkannya dengan struktur geladak kapal tugboat konvensional. Penggunaan panel sandwich dinilai mampu meningkatkan efisiensi struktur kapal melalui pengurangan berat dengan tetap mempertahankan kekuatan. Metode yang digunakan adalah simulasi numerik berbasis metode elemen hingga, dengan memvariasikan sudut core, ketebalan faceplate, dan ketebalan core untuk menilai nilai tegangan maksimum, deformasi maksimum, dan berat total struktur. Hasil analisis menunjukkan bahwa konfigurasi panel sandwich dengan sudut 66°, ketebalan faceplate 3 mm, dan core 2 mm memberikan hasil paling optimal, dengan tegangan maksimum sebesar 75,37 MPa, deformasi maksimum 0,39 mm, dan berat struktur sebesar 10,23 ton. Model ini mampu menurunkan berat hingga 25% dibandingkan struktur geladak konvensional, serta tetap memenuhi batas kekuatan dan deformasi yang diizinkan. Dengan demikian, panel sandwich model ini dapat menjadi pilihan dalam desain struktur kapal yang lebih ringan dan efisien secara struktural.

This research aims to optimize a U-Beam Corrugated Core sandwich panel model as a ship deck structure and compare its performance with that of a conventional tugboat deck structure. The use of sandwich panels is considered to improve structural efficiency by reducing weight while maintaining strength. The method employed is numerical simulation based on the finite element method (FEM), with variations in core angle, faceplate thickness, and core thickness to evaluate maximum stress, maximum deformation, and total structural weight. The analysis results indicate that the sandwich panel configuration with a 66° core angle, 3 mm faceplate thickness, and 2 mm core thickness provides the most optimal performance, yielding a maximum stress of 75,37 MPa, a maximum deformation of 0.39 mm, and a structural weight of 10.23 tons. This model achieves a weight reduction of up to 25% compared to the conventional deck structure while still complying with allowable stress and deformation limits. Therefore, this sandwich panel model presents a promising alternative for designing lighter and structurally efficient ship structures.
