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 RX-122 rocket is an experimental rocket series developed by the Technology Centre for Rocket-BRIN. The lightweight design of the RX-122 rocket motor tube is an essential requirement for improving the rocket's flight performance. The objective of this research is to identify a rocket motor tube design that offers both safety and minimal weight. A total of 12 different design configurations for the rocket motor tube are examined using numerical methods assisted by Ansys software. Aluminium 6061-T6 material was chosen to withstand an internal operating pressure load of 10.5 MPa. The design involves examining a range of wall thickness options, including 4 and 5 mm, cap thickness options of 15 and 20 mm, and fillet radii of 10, 15, and 20 mm. This approach provides a comprehensive and systematic method to achieve optimal structural performance under operational stress conditions, ensuring that only safe yet lightweight configurations are selected. This evaluation, which integrates the exploration of wall, cap, and fillet dimensions, offers an innovative framework to optimize the balance between safety and weight. The findings indicate that only the 12th design, featuring a wall thickness, cap thickness, and fillet radius of 5, 20, and 20 mm, satisfies the specified criteria. The method demonstrates a practical advantage in refining rocket design with high efficiency and accuracy, reducing trial-and-error in experimental setups.

Abstract

The quality of corn is essential to determine whether the corn is still suitable for consumption and what type of corn it is. Corn is one type of vegetable that is indispensable for the nutritional needs of the Indonesian people today and is a mixture of other essential ingredients. Corn is rich in fiber, which is good for improving digestion and overcoming constipation, controlling blood sugar levels, maintaining heart health, overcoming depression, maintaining eye health, and preventing diverticulitis. In this research, image recognition is used to determine and detect the content of aflatoxin, which is one type of abnormality or disorder in corn. This affects the quality of corn, whether corn is suitable for human consumption, and what impact aflatoxin has on the human body. on testing using parameters Non UV image, SGW Filter Image θ = 0, 90, 180 and 270, and The resulting SGW image with the number of orientations N = 4, θ = θ + pi/N, and θ = θ + 2*pi/N, The aflatoxin content in humans can cause carcinogenic or liver cancer and acute necrosis, cirrhosis, and carcinoma in the animal liver.

Abstract

The rocket motor is an important part of rockets. The rocket motor works using the pressure vessel principle because it works in an environment with high pressure and temperature. This paper investigates the von Mises stress that occurs in thin-walled cylinders and safety factors for rocket motor cases due to the influence of the wall thickness and internal pressure. Dimensions of the cylinder length are 500 mm, outer diameter is 200 mm, and cap thickness is 30 mm. The wall thickness is varied 6, 7, 8, and 9 mm, while the internal pressure is varied 8, 9, and 10 MPa. Stress analysis is performed using the finite element method with Ansys Workbench 2019 R3 software. The simulation results show that the maximum von Mises stress decreases with increasing wall thickness. The maximum von Mises stress increases with increasing internal pressure. The material has a safety factor higher than 1.25 for all variations in wall thickness and internal pressure. It means that the material can withstand static loads. The verification process is done by comparing the results of finite element analysis with analytical calculations for maximum hoop stress and maximum axial stress with a fixed boundary condition. The results of maximum hoop stress and maximum axial stress using finite element analysis and analytical calculations are not significantly different. The percentage of errors between analytical calculations and finite element analysis is less than 6 percent.
