Desain dan Simulasi Elemen Hingga Gantry Crane Kapasitas 9 Ton Menggunakan Autodesk Inventor 2017
No full textCurrently, the gantry crane in LAPAN Garut still uses steel material. The steel material is protected using a coating to minimize the impact of corrosion. However, this method is less efficient, considering the corrosion rate in LAPAN Garut is very high because it is located on the coast of Cilauteureun. It also creates problems in terms of maintenance because it has to be done regularly and periodically repainting. In addition, not all equipment is available maintenance funds every year. The objective of this paper is to design and analyze the stress of a gantry crane with a capacity of 9 tons using Aluminum 6061 material. The material used is three units of JIS G 3192 H standard frame (I-shape) with a size of 150 x 150 x 7 mm, four units of JIS G 3466 frame (square profile) with a size of 150 x 150 x 6 mm, and four units of JIS G 3466 frame (square profile) with a size of 125 x 125 x 6 mm. Finite element analysis is performed using Autodesk Inventor Professional 2017 software. The simulation results show that the gantry crane has a mass, von Mises stress, deformation, and safety factors respectively at 165.36 kg; 132.9 MPa; 13.67 mm; and 2.07

Effect of Load Variations on The Static Stress and Fatigue Life Estimation of Crane Hook Using Finite Element Method
No full textThe crane hook is one of the critical components of a crane that functions to lift objects from one place to another. This equipment is often used for the assembly process of rocket motors. This study aims to examine the effect of load variations on the static stress and fatigue life estimation of Crane Hook. The analysis was carried out using the finite element method with the help of the Ansys Workbench software. Loads of crane hook were varied 5, 6, 7, 8, 9, and 10 Ton. The type of loading is full-reserved, the type of analysis is stress life, and the theory used is the Gerber mean stress theory. The material used is Al 6061-T6. Static stress simulation results show that the crane hook can withstand dynamic loads of up to 10 Tons because it has a safety factor of more than 2, to be exact 2.03. The fatigue life simulation results show that the hook crane fails to reach a fatigue life of 1 million cycles at a load of 10 Tons
