Abstract

Pengurangan berat struktur kapal adalah salah satu optimisasi dari perkembangan desain kapal. Kriteria tersebut dapat dicapai dengan melakukan inovasi pada bagian konstruksi dengan mengembangkan pelat yang dapat dipasang di kapal seperti geladak yang akan analisa pada penelitian ini tanpa menggunakan penegar yaitu sandwich panel. salah satu jenis core pada sandwich panel adalah bentuk heksagonal. Bentuk sarang lebah atau heksagonal merupakan salah satu geometri yang sangat efisien sehingga sangat berpotensi untuk mengurangi berat struktur. Penggunaan honeycomb-core sandwich panel pada geladak kapal tentunya perlu memperhatikan aspek keamanan untuk memastikan kekuatan struktur geladak mampu bertahan dikenai beban. Sehingga kekuatan geladak dengan honeycomb-core sandwich panel dapat dicek dengan finite element method. Analisis yang dilakukan pada penelitian ini adalah mencari honeycomb-core sandwich panel yang paling optimal dilihat dari segi tegangan, deformasi dan berat konstruksi jika dibandingkan dengan geladak berpenegar. Terdapat 3 model honeycomb-core sandwich panel yang dibedakan dari ketinggian core-nya. Model 1 memiliki tinggi core 25 mm, model 2 memiliki tinggi core 35 mm dan model 3 memiliki ketinggian core 45 mm. Ketiga model tersebut memiliki variasi ketebalan core yang nilainya dimulai 1 mm sampai 5 mm. Hasil percobaan didapatkan desain honeycomb-core sandwich panel yang paling optimal adalah desain pada model 3 dengan tinggi core 45 mm, ketebalan core 2 mm, besar tegangan yaitu 58,2 Mpa dimana nilai ini sudah kurang dari tegangan izin dan kurang dari tegangan pelat berpenegar dengan besar deformasi 3,906 mm dan berat 1,2 ton.

Reducing the weight of the ship structure is one of the optimizations of ship design developments. These criteria can be achieved by innovating in the construction section by developing plates that can be mounted on ships such as the deck which will be analyzed in this study without the use of stiffeners, namely sandwich panels. one type of core on a sandwich panel is a hexagonal shape. The honeycomb or hexagonal shape is one of the most efficient geometries so it has the potential to reduce the weight of the structure. The use of honeycomb core sandwich panels on ship decks certainly requires safety considerations to ensure that the strength of the deck structure can withstand the load.. So that the strength of the deck with honeycomb-core sandwich panels can be checked with the finite element method. The analysis carried out in this study was to find the most optimal honeycomb-core sandwich panel in terms of stress, deformation and structure weight when compared to reinforced decks. There are 3 models of honeycomb-core sandwich panels which are distinguished by the height of their cores. Model 1 has a core height of 25 mm, model 2 has a core height of 35 mm and model 3 has a core height of 45 mm. The three models have core thickness variations whose values start from 1 mm to 5 mm. The experimental results show that the most optimal honeycomb-core sandwich panel design is the design in model 3 with a core height of 45 mm, a core thickness of 2 mm, a stress of 58.2 MPa where this value is already less than the allowable stress and less than the stress of the reinforced plate with large deformation 3.906 mm and weighs 1.2 tons.
