Abstract

Kapal wisata glass bottom adalah kapal wisata yang dirancang sebagai salah satu alternatif cara untuk menikmati keindahan bawah laut. Sebagai kapal wisata terdapat salah satu aspek yang perlu diperhatikan yaitu getaran pada kapal. Getaran tersebut bersumber dari kamar mesin dan dapat menimbulkan getaran berlebih yang berpotensi menjadi resonansi sehingga dapat mengganggu kenyamanan penumpang kapal. Analisis menunjukkan bahwa terjadi resonansi pada kecepatan operasional kapal yaitu 8–10 knot akibat nilai frekuensi alami struktur (dengan 484 mode) mendekati frekuensi eksitasi yang dihasilkan oleh variasi kecepatan kapal dan putaran mesin. Untuk mengatasi masalah ini, dilakukan modifikasi struktur dengan cara meningkatkan kekakuan, sehingga tidak lagi terjadi resonansi. Selanjutnya, dilakukan analisis modal dynamic berupa displacement, velocity, dan acceleration pada model sebelum dan sesudah modifikasi. Hasil analisis yang menunjukan bahwa getaran yang terjadi masih berada dalam batas yang diizinkan berdasarkan standar ISO 6954

Glass bottom tour ship is a tour ship designed as an alternative way to enjoy the beauty of the underwater world. As a tour ship, there is one aspect that needs to be considered, namely vibrations on the ship. The vibrations originate from the engine room and can cause excessive vibrations that have the potential to become resonance so that they can interfere with the comfort of ship passengers. The analysis shows that resonance occurs at the ship's operational speed of 8-10 knots due to the natural frequency value of the structure (with 484 modes) approaching the excitation frequency generated by variations in ship speed and engine speed. To overcome this problem, structural modifications were made by increasing stiffness, so that resonance no longer occurs. Furthermore, a modal dynamic analysis was carried out in the form of displacement, velocity, and acceleration on the model before and after modification. The results of the analysis showed that the vibrations that occurred were still within the permitted limits based on the ISO 6954 standard
