Abstract

Penelitian ini bertujuan untuk menganalisis desain bucket excavator dengan metode elemen hingga. Proses desain bucket dilakukan dengan menggunakan software Solidworks 2016. Proses analisis metode elemen hingga dilakukan dengan memanfaatkan software ANSYS 18.1 guna untuk mencari von mises stress, displacement, regangan, dan safety factor pada desain bucket. Hasil menunjukkan bahwa von mises stress yang dihasilkan sebesar 7,72 N/m2 , regangan maksimum pada desain bucket sebesar 2,25 mm, dan regangan terjadi sebesar 2,08835 x106 serta safety factor yang dihasilkan sebesar 3,6.

Abstract

Aluminum foil is used more often than actual aluminum in everyday life because aluminum is actually quite unstable and is not suitable for securing heavy containing objects. For car wheels, aluminum is mixed with manganese and then hardened to withstand the load. Using aluminum alloys requires an electroplating process to increase corrosion resistance, decorative value and friction resistance. The purpose of this study was to determine the properties of anodized cathode aluminum alloy and the required coating time. In this study, a quantitative experiment used 20 samples. The results showed that there were defects in the aluminum alloy lattice, but not too significant. Different corrosion rate values were shown using electrolysis periods of 30 minutes and 60 minutes combined with anode-cathode distances of 5 cm, 10 cm and 15 cm. The group with 30 minutes of coating time and 5 cm anode-cathode distance had the highest corrosion rate (0.853 mm/year), while the group with 30 minutes of coating time and 10 cm anode-cathode distance had the lowest corrosion rate (0.610). The group with 60 minutes of coating time and 10 cm distance between the anode and cathode had the highest corrosion rate of 1,564 mm/year, while the group with 60 minutes of coating time and 15 cm distance had the lowest corrosion rate. The anode-cathode distance partially affects the corrosion rate of aluminum alloy electroplating. The smaller the distance between the anode and cathode, the higher the corrosion rate of the aluminum alloy. The longer the coating lasts, the higher the corrosive rate of the Al alloy.

Abstract

Body armor is personal protective equipment or shield clothing for soldiers that has existed since Roman times until now. The function of body armor is to protect the body from attacks by foreign objects by absorbing energy. Body armor must have ballistic resistance and stabbing resistance, however, body armor that is often found usually has a high anti-ballistic level but is low in receiving stabbing attacks. STF (Shear Thickening Fluid) is a composite material which is unique in that the viscosity level can change in a way that causes the liquid dispersion to become solid and allows for increased stabbing resistance. This research began by making Kevlar samples which were then mixed with STF and then subjected to tensile testing to obtain material properties that were useful for simulating with FEM. The simulation is intended to analyze the rate of energy absorption that occurs in the sample. The results show that the kinetic energy absorption rate of the bullet is absorbed at a viscosity of 87%. The small energy that occurs is also absorbed in the form of frictional resistance with a value of 11.9%. The identified comparison results show that in cases 1-3 the percentage of viscosity is high so it is viscous, whereas in case 4 the direct reflection of the viscosity is low so it is close to liquid.
