Abstract

Stress Distribution Analysis on Bolt Head with Various Fillets Using PhotoelasticityMethod. A geometry modification can be use to reduce stress concentration. This research isinvestigating the influence offillet radius in the head ofbolt. Different than most commonbolt, thefillet ismade at the bottom surface of head around its neck. To show the stress distribution we use classicalexperimental mechanics method, photo elasticity. Loading comesfrom a lead screw and measured by aload cell connected to a computer data logger. As the result, a 5 mm fillet radius may reduce maximumshear stress up to 35%than nofillet radius, so its effective to minimize stress concentration in head bolt.

Abstract

This research investigated the design of the overhead crane supports with capacity of 2 x 20 ton. The crane design was modeled using both solids and surfaces, and the analysis was performed with finite element method. The results from the analysis verified the stress level, deflection level from crane column and runway beam, and the critical load of buckling for crane column to prevent the structure failure. The stress level result was compared to the material yield strength to find out whether or not  the design is safe. It is concluded that the stresses arising from the rail beam and column are still within the permissible limits so that the design is safe to use.

Abstract

Equipment has been made to simulate a discrete system vibration of one degree of freedom. The aim is to obtain equipment for learning for students in the field of mechanical vibration. Vibration simulation includes free vibration and forced vibration of discrete system in one degree of freedom. The main parts of this equipment are rigid rods with mass of 2.6 kg, vibrators with mass of  3.385 kg, spring with stiffness of 3738 N/m and loading masses. A rigid rod of 0.775 m in length is supported by a hinge on one end and hung on a spring in another position. The vibrator is rotated by an electric motor and the rotation can be adjusted from 90-1600 rpm. The vibrator is mounted on a rigid object at the position of 0.285 m, 0.385 m, 0.485 m and 0.585 m from the hinge. A spring with stiffness of 3738 N/m is placed on a rigid object at the position of the hinge. The loading masses of 1.08 kg and 2.08 kg are mounted on a rigid beam in a row at the position of 0.685 m from the hinge. For the free vibration experiments, the natural frequency for each position of vibrator is searched experimentally and theoretically. It is found that the results of the two are similar. For the forced vibration experiments, graphs of vibrational responses are constructed in the frequency domain, then the resonance frequencies are compared to the natural frequency results from the free vibration experiment. Apparently the results are very close. This shows that the research equipment made is reliable and can be used as a student learning tool.

Abstract

The PPCW railroad flatcars is railroad flatcars used to transport container loads with a maximum load capacity of up to 42 tons. In its use, these railroad flatcars are used to transport the cement bags in the pallet arrangement resulting in crack in the bottom frame of the PPCW railroad flatcars structure. The purpose of this analysis is to find out stress value and deformation value that occurred in the railroad flatcars due to the cement bags loading. The analysis process begins with modeling according to the original size of the railroad flatcars which is then followed by providing the support, gravity, loads, and material specifications used. Based on the result of analysis that has been obtained from the load of cement bags of 546,000 N and ratchet lashing of 900,000 N on the frame of PPCW railroad flatcars, we obtained the maximum von Mises stress value of 231.91 MPa arising on the bottom frame of the PPCW railroad flatcars structure as the site of cracking and the maximum total deformation value of 19.526 mm arising in the center of the railroad flatcars. The PPCW railroad flatcars made from SS400 with yield strength value of 245 MPa. Therefore, it was found that the value of stress arising in the railroad flatcars is still in the safe area and is allowed.

Abstract

Truk kategori II populer di kalangan para pelaku  usaha di Indonesia sebagai sarana angkutan barang. Pengoperasian truk dengan beban berlebih sering terjadi dan potensial menimbulkan kerusakan komponen. Penelitian ini membahas kerusakan rear axle housing truk katagori II dengan JBB 7,5 ton. Data yang didapat dari PT. KY di awal tahun 2018, menunjukkan jenis kerusakan yang teradi pada truk kaegori II dengan GVW 7,5 ton yaitu patah pada area sambungan spindle dan housing. Untuk itu dilakukan analisa dari aspek kekuatan rear axle housing mengunakan metode elemen hingga (MEH) dengan model 3D yang didapat dari PT. KY. Tujuan penelitian ini adalah untuk mengetahui distribusi tegangan pada rear axle housing dan membandingkan dengan kerusakan rear axle housing untuk memperkirakan apakah ada kelemahan dalam desain saat itu. Analisis dilakukan untuk beban sesuai desain dan beban berlebih. Material yang digunakan sebagai acuan SAPH 540, hasil analisis MEH menunjukkan bahwa desain rear axle housing yang ada cukup aman termasuk untuk kondisi beban berlebih. Analisis pada bagian yang patah menunjukkan tegangan yang terjadi di bawah tegangan luluh material. Kemungkinan penyebab kegagalan pada komponen rear axle housing adalah masalah material atau masalah proses produksi atau penyebab yang lain

Abstract

Penelitian perancangan mobil hemat energi dan mengikuti lomba Kontes Mobil Hemat Energi (KMHE) merupakan salah satu cara penanggulangan dari masalah meningkatnya jumlah bahan bakar yang digunakan. KMHE ialah lomba yang diselenggarakan oleh Kemedikbudristek dan Puspresnas yang memiliki 2 kategori utama, yaitu prototype dan urban concept. Pada penelitian ini dilakukan perancangan rangka sasis mobil KMHE kategori prototype dengan menggunakan hollow 20x40x1,5 mm dan pipa tubular ¾ inch x 1,5 mm dengan bobot rangka total 6,13 kg. Material yang digunakan berjenis aluminium A6061. Untuk menentukan kuat atau tidaknya rangka pada saat perancangan rangka mobil KMHE dilakukan analisis rangka menggunakan perangkat lunak ANSYS 19 R3. Penggunaan perangkat lunak ANSYS bertujuan untuk menguji atau menganalisis deformasi, tegangan ekuivalen, faktor keamanan pada desain rangka. Hasil simulasi pada rangka menunjukkan nilai tegangan ekuivalen 142,18 MPa, nilai deformasi maksimum sebesar 3,24 mm, nilai faktor keamanan 1,94.

Abstract

In today's industrial needs, the most common material handling equipment in daily uses is hand truck, because of the price itself is quite cheap, flexible, and easy to operate. However, one of the weaknesses of the hand truck is it can’t through places that have different heights such as stairs. To overcome this problem, the hand truck will be modified using a timing belt which make it possible the hand truck to pass through stairs. The design modification begins with collecting the main hand truck data, followed by making several design concepts, selecting the suitable design modification concept to overcome the staircase problem and finally analyzing and calculating the components used. Design modifications are illustrated in 3D shape using Solidworks software. The result of the modified design is an electric hand truck with a timing belt with dimensions of (1037 x 455 x 1102) mm for stair-climbing with a maximum angle of stair slope equal to 30 degrees which is able to lift a load of 100 kg at a speed of 0.8 m/s.

Abstract

Cranes are indispensable heavy equipment that can lift and move hefty loads in factories, warehouses, and construction sites with ease. Safe operation of cranes is vital because errors in crane design can make it prone to failures, such as broken trusses, which can cause the crane to collapse and hit people around the crane. This research aims to analyze vibrations and modal Truss Gantry Cranes using ANSYS software to determine natural frequencies, critical points, and deformations that can result in damage. To test the Truss Gantry Crane's structural strength with ANSYS software, the Static Structural design program is used to analyze the deformations and stresses experienced by the crane, the Modal design program is utilized to determine its natural frequency, and the Harmonic Response is used to determine its reaction to natural frequencies. Static Structural testing was carried out 30 times, starting from a load of 500 N and increasing to a maximum load of 15000 N, with an interval of 500 N. The test results showed that the Truss Gantry Crane vibrates violently at frequencies of 24 Hz, 68 Hz, and 94 Hz. Further analysis revealed a linear regression analysis for the maximum load and maximum stress that can be applied to the Truss Gantry Crane as follows: y = 0,0091 x + 0,1981
