Abstract

Penelitian ini bertujuan untuk menganalisis kekuatan struktur geladak kendaraan kapal Ro-Ro dengan memanfaatkan material sandwich panel berbasis polyurethane sebagai alternatif material ringan dan kuat. Studi dilakukan menggunakan metode elemen hingga (Finite Element Method/FEM) dengan software elemen hingga untuk mengevaluasi respon tegangan dan deformasi terhadap tiga variasi posisi beban kendaraan. Model geladak dibandingkan antara konfigurasi pelat konvensional dan pelat sandwich dengan faceplate ASTM A36 setebal 6 mm dan core polyurethane setebal 10 mm. Hasil analisis menunjukkan bahwa struktur geladak dengan sandwich panel memiliki kemampuan mereduksi tegangan dan deformasi secara signifikan dibandingkan struktur konvensional. Tegangan maksimum tertinggi sebesar 214 MPa terjadi pada variasi pertama dengan beban ekstrem 40 ton, sedangkan deformasi tertinggi sebesar 5,089 mm masih dalam batas aman. Variasi ketiga menunjukkan performa paling optimal dengan tegangan dan deformasi paling rendah. Selain itu, penggunaan material sandwich berhasil menurunkan berat struktur hingga ±36,5%. Dengan demikian, penggunaan sandwich panel polyurethane direkomendasikan sebagai solusi efisien untuk struktur geladak kapal Ro-Ro.

This research aims to analyze the structural strength of the vehicle deck on a Ro-Ro ship using polyurethane-based sandwich panels as a lightweight and high-strength alternative material. The study is conducted using the Finite Element Method (FEM) with Abaqus software to evaluate stress and deformation responses under three different vehicle load positions. The deck model is compared between conventional plate configurations and sandwich panels with 6 mm ASTM A36 faceplates and 10 mm polyurethane cores. The analysis results show that the deck structure using sandwich panels significantly reduces stress and deformation compared to conventional structures. The highest maximum stress, 214 MPa, occurs in the first variation under extreme loading of 40 tons, while the highest deformation is 5.089 mm—still within allowable limits. The third variation provides the most optimal performance with the lowest stress and deformation. Furthermore, the use of sandwich materials reduces the overall structure weight by approximately 36.5%. Therefore, polyurethane sandwich panels are recommended as an efficient solution for Ro-Ro ship deck structures.
