Abstract

The study examines the effect of the load on fatigue life prediction of an outdoor AC bracket using the finite element method. Outdoor AC bracket design uses Autodesk Inventor Professional 2017, while finite element analysis uses Ansys Workbench. The outdoor AC bracket is subjected to a load of 20, 25, 30, and 35 kg with a fully-reserved type of loading. Gerber's mean stress theory is used to predict fatigue life. The outdoor AC bracket material uses Aluminum alloy 5052. The simulation results show that the outdoor AC bracket has a minimum fatigue life for loads of 20, 25, 30, and 35 kg, respectively is 1 x 108, 1.49 x 107, 1.93 x 106, and 6.64 x 105 cycles. Whereas the safety factor for minimum fatigue life for loads of 20, 25, 30, and 35 kg is 1.65; 1.32; 1.10; and 0.58. It shows the outdoor AC bracket can withstand the fatigue life of up to a minimum of 106 cycles for loads of 20, 25, and 30 kg because it has a safety factor of more than 1. While the 35 kg load of outdoor AC bracket fails to reach a minimum fatigue life of 106 cycles due to fatigue life prediction is only reached 6.64 x 105 cycles with a safety factor of less than 1, which is 0.58.

Abstract

The main landing gear is one of the important components in UAV aircraft. This paper aims to analyze the natural frequency of the main landing gear and determine its normal mode shape. This analysis is important so that no resonance causes damage to the main landing gear components. The main landing gear uses Aluminum 6061 material and the analysis is carried out using the finite element method with the help of Ansys Workbench software. The analysis showed that the natural main landing gear frequencies for mode 1 to mode 6 were 76.04 Hz, 85.07 Hz, 167.82 Hz, 201.92 Hz, 288.39 Hz, and 327.00 Hz, respectively. The maximum deformation of the main landing gear for mode 1 to mode 6 is 33.73 mm, 35.35 mm, 48.16 mm, 44.62 mm, 38.14 mm, and 41.51 mm, respectively.

Abstract

The lightweight design of the rocket motor tube is a critical requirement for enhancing the rocket's flight performance. This study assesses the impact of wall thickness, cap thickness, and fillet radius on structural strength and the optimization of rocket motor tube weight using the finite element method with the assistance of Ansys software. A total of 12 finite element model variations, utilizing Aluminium 6061-T6, were developed and subjected to a uniform internal operating pressure load of 10 MPa. The design includes wall thickness variations of 8 and 10 mm, cap thickness options of 25 and 30 mm, and fillet radius dimensions of 20, 25, and 30 mm, allowing for a comprehensive comparison to achieve the required minimum safety factor while minimizing structural weight. The research concludes that increasing the fillet radius is a more recommended approach compared to increasing wall thickness and cap thickness. The results indicate that Model 9, with wall thickness, cap thickness, and fillet radius dimensions of 10 mm, 25 mm, and 30 mm, respectively, is the optimal choice due to its lightweight construction.
