Motor roket adalah bagian penting dari roket. Motor roket bekerja menggunakan prinsip bejana tekan karena bekerja di lingkungan dengan tekanan dan suhu tinggi. Makalah ini menyelidiki tegangan von Mises yang terjadi dalam silinder berdinding tipis untuk tabung motor roket dan faktor keamanan karena pengaruh radius fillet dan ketebalan cap. Dimensi panjang silinder adalah 400 mm, diameter luar 122 mm, dan ketebalan dinding 5 mm. Radius fillet divariasikan 2, 4, 6, dan 8 mm, sedangkan ketebalan cap divariasikan 5 dan 10 mm. Silinder berdinding tipis dikenai tekanan internal konstan yaitu 6 MPa. Analisis tegangan dilakukan menggunakan metode elemen hingga dengan perangkat lunak Ansys Workbench 2019 R3. Perbandingan nilai tegangan hoop dan longitudinal antara perhitungan analitik dan simulasi digunakan untuk proses verifikasi. Hasil simulasi menunjukkan bahwa ketika radius fillet dan ketebalan cap meningkat, tegangan Von Mises menurun. Material memiliki faktor keamanan lebih tinggi dari 1,25 ketika ketebalan cap 10 mm dengan radius fillet 4, 6, dan 8 mm.

Penggunaan gawai di lingkungan kerja saat ini sudah menjadi kebutuhan umum. Gawai menjadi salah satu produk teknologi yang sangat penting dalam menunjang produktifitas kerja dan memudahkan komunikasi antar pegawai. Kondisi ini menyebabkan stasiun pengisian gawai menjadi media yang sangat penting untuk menjaga konektivitas antar pegawai. Penelitian ini bertujuan mendesain stasiun pengisian gawai menggunakan material Polikarbonat dan HDPE. Pemilihan kedua material tersebut didasarkan pertimbangan sifat isolator listrik yang tak dimiliki oleh material logam. Hal ini sangat penting untuk menjaga keamanan dan keselamatan dalam penggunaannya. Analisis elemen hingga dilakukan menggunakan software Autodesk Inventor Professional 2017. Variasi beban yang digunakan adalah 4 kg, 5 kg, dan 6 kg. Hasil simulasi menunjukkan material HDPE dengan variasi beban 4 kg, 5 kg, dan 6 kg memiliki faktor keamanan berturut-turut sebesar 2,65, 2,12, dan 1,77. Faktor keamanan menggunakan material Polikarbonat dengan variasi beban 4 kg, 5 kg, dan 6 kg berturut-turut sebesar 7,77, 6,22, dan 5,18.

The rocket motor tube is the main component of the Dextrose rocket. This paper aims to investigate the effect of tube length and fillet radius on the safety factor of a dextrose rocket motor tube using Ansys Workbench. The Dextrose rocket tube uses Al 6063-T5 material with an outer diameter of 32 mm, a wall thickness of 3 mm, and internal pressure of 5 MPa. The rocket motor tube length is varied by 200, 250, 300, and 350 mm. The fillet radius uses variations of 3, 4, and 5 mm. The analysis was carried out using the finite element method with the help of Ansys Workbench. The simulation results show that the safety factor does not have a significant effect on changes in the length of the rocket tube. The safety factor increases as the fillet radius increases.

The landing gear is one crucial component in a UAV aircraft structure. Landing gear serves as the main supporting component of aircraft load when landing and take off. The paper aims to examine the effect of landing speed on the fatigue life of the tricycle landing gear of the UAV aircraft. The design of the tricycle landing gear frame uses Autodesk Inventor Professional 2017, while the analysis of fatigue life uses Ansys Workbench software. Landing speeds is varied 4 m/s, 6 m/s, 8 m/s, and 10 m/s. The fatigue life prediction using Gerber means stress theory with a fully-reserved type of loading. The landing gear material uses Aluminum alloy 6061. The simulation results show that the tricycle landing gear frame with landing speeds of 4, 6, 8, and 10 m/s has a minimum fatigue life of 1.00 x 108, 8.93 x 107, 4.30 x 106, 7.17 x 105 cycles. While the tricycle landing gear frame with landing speeds of 4, 6, 8, and 10 m/s has a minimum safety factor of 2.39, 1.59, 1.19, and 0.95. It means that the relationship between landing speed is inversely proportional to the fatigue life of the landing gear frame. The higher the landing speed, the lower the fatigue life of the landing gear frame. At a landing speed of 10 m/s, the landing gear frame fails to reach a minimum fatigue life of 1 million cycles.
