Abstract

This paper discusses the modelling and simulation of welding process based on the finite element method (FEM) in order to predict the welding distortion of tractor wheel blades. Two FEM modellings are needed to obtain the welding distortion models, namely thermal and elasto-plastic. The effect of welding thermal is assumed as tendon force and to be used as input of the analysis of elasto-plastic modelling. Welding distortion simulation results were verified using the experimental data. The verification results have shown similar shape of the welding deformation between simulations and experimental. Also, deviation value of displacement distortion between simulation and experimental is small. Hence, the simulation of welding deformation modelling using thermal elasto-plastic FEM can be used to predict the welding distortion of tractor wheel blades. Based on simulation results, the shape of radial and axial displacement distortion due to welding the blade with serial sequence was larger than that of the shape distortion due to welding of the blade with a recommended sequence. After welding simulation of those of 16 wheels tractor blades, the predicted value of displacement distortion due to welding of the blade with serial sequence is equal to 3,393mm, which was larger than that of 1,440mm due to welding of the blade with recommended sequence.

Abstract

Magnesium merupakan salah satu material bobot ringan yang sangat penting, terutama di bidang otomotif, dan biomedik. Aplikasi material magnesium dan paduannya di bidang material biomedik didasarkan pada sifat magnesium yang sangat mirip dengan sifat tulang manusia dan memiliki biocompatibility yang baik serta luluh di dalam tubuh. Aplikasi material magnesium juga banyak dikembangkan dengan cara ditanam (implan). Material paduan magnesium memiliki beberapa kelebihan secara kimia dan fisika, namun  dalam proses pemesinan paduan magnesium dikenal sebagai material jenis logam yang mudah terbakar, terutama pada saat proses pemesinan dengan kecepatan tinggi. Dalam penelitian ini, sudut mata pahat (point angle), pelumas dan parameter pengeboran dianalisa untuk mengetahui pengaruhnya terhadap nilai kekasaran permukaan, kebulatan dan ketegaklurusan. Pada penelitian ini disain yang digunakan adalah Metode Taguchi L18 yang terdiri dari 3 faktor 3 level dan 1 faktor 2 level. Hasil penelitian menunjukkan bahwa kekasaran permukaan dipengaruhi oleh adanya kontribusi dari sudut sudut mata pahat18,9% dan lubrikan 14,5%. dimana sudut mata pahat adalah 650 dengan lubrikan minyak sintetis.  Kebulatan dipengaruhi oleh sudut mata pahat 450 dari proses pengeboran, terutama jika terjadi interaksi pada kadar pemakanan 0,2 mm/rev dan lubrikan sintetis. Keakuratan sisi potong/cutting edge berakibat pada gaya tangensial sehingga berpengaruh pada kestabilan putaran dan kebulatan hasil pengeboran. Nilai ketegaklurusan magnesium AZ31 dalam proses pengeboran sangat dipengaruhi pula oleh parameter pemotongan kadar pemakanan yang menghasilkan signifikansi P = 0,044 , sedangkan nilai signifikansi yang paling tinggi adalah interaksi antara kadar pemakanan 0,1 mm/rev dengan lubrikan sintetis  pada P = 0,041.

Abstract

Produk berbahan baku plastik semakin banyak dijumpai, mulai dari peralatan rumah, komponen elektronik hingga otomotif. Hal ini dikarenakan beberapa kelebihan yang dimiliki oleh plastik seperti ringan dan tahan karat, lebih murah dibandingkan dengan produk logam atau kayu serta proses pengerjaannya relatif mudah. Proses pembentukan produk plastik yang palingg umum digunakan adalah injection molding. Penggunaan plastik yang semakin mendominasi penggunaan material menuntut suatu usaha untuk mengurangi waktu dan biaya produksi, salah satu caranya yaitu dengan memanfaatkan program simulasi sebelum dilaksanakan di lantai produksi. Dengan simulasi pemoderan dapat diketahui ketebalan optimal suatu produk, sehingga produk yang dihasilkan memiliki ketebalan seminimal mungkin dengan kualitas yang dapat diterima. Penelitian ini akan mensimulasikan variasi ketebalan dinding terhadap waktu pengisian, suhu aliran depan, waktu pendinginan, cacat garis dan udara terperangkap. Variasi ketebalan yang dipilih yaitu 1 mm, 1,5 mm, 2 mm, 2,5 mm, 3 mm, 3,5 mm dan 4 mm. Dari hasil simulasi didapatkan kesimpulan bahwa ketebalan optimal model adalah sebesar 2 mm, dimana pada ketebalan ini memiliki waktu pengisian 2,753 detik, suhu aliran depan 230,3oC, dan waktu pendinginan 25,8 detik. Cetakan (mold) mulai dapat terisi cairan plastik secara penuh mulai pada ketebalan 2 mm. Semua variasi ketebalan mengalami cacat produk yang semakin meningkat seiring dengan bertambah ketebalan model.

Abstract

Friction welding is a metal joining technique without melting beforehand in which the process is to combine the rotation rate in one of the work materials. In the previous studies, the forging pressure parameters used for friction welding did not have a definite reference to the strength of the joint in friction welding. This project is to make initial design of forging measuring instrument for application of friction welding. The steps include conceptual design, embodiment process, and performance analysis. The conceptual design result includes hollow iron U-shape, telescopic iron, and telescopic iron with screw. The measuring system uses a 500 kg load cell, Arduino Leonardo, HX711amplifier, and data logger. Then, after all components are assembled, the load cell calibration is performed to determine the calibration factor. The next stage is to do pressure test to see the performance of forging measuring instrument of friction welding.

Abstract

Dalam pembedahan ortopedi, mata bor berfungsi sebagai alat bantu membuat lubang untuk sekrup dalam upaya perbaikan fraktur atau pemasangan perangkat prostetik. Selama proses pengeboran berlangsung akan meyebabkan peningkatan suhu pada area pengeboran, kenaikan suhu melampaui batas yang diijinkan akan mengakibatkan matinya sel-sel tulang akibat kehilangan suplai darah yang disebut dengan nekrosis. Untuk mencegah peningkatan suhu berlebihan tersebut, salah satu cara yang dapat dilakukan adalah dengan melakukan pemilihan geometri mata bor menggunakan finite-element analysis model tiga dimensi untuk mendapatkan nilai temperatur pengeboran tulang yang serendah mungkin. Penelitian ini berfokus pada nilai point angle 118°, yang dikombinasikan dengan nilai helix angle 13°, 20°, 28° dan 30°. Dari kombinasi tersebut menghasilkan nilai temperatur optimal pada helix angle 28° dengan suhu maksimum pada 38.814° C.

Abstract

A poor selection of welding joints is one cause of damage or fractures in welding. Butt joint is one type of welding joint that has many advantages compared to other types. Because during the welding process, the joint area will be completely filled with filler metal. In addition, the manufacturing process of butt welding joint is easy, so it is widely used in the industrial world. In the welding process, the heat input and the cleanliness of the joint surface area must be considered in order not to cause failure of the welding joint. To determine the value of toughness and hardness, the welded specimens were tested using the impact test and hardness test. This research aims to determine the effect of butt welding joint type half V, single V, and double V on the impact toughness and hardness of the aluminium 5083 specimens MIG welding results. The results showed that the highest hardness value was shown by a single V butt joint with a value of 34.0 HRB and the lowest hardness value was shown by a double V butt joint 27.0 HRB. In the impact test, the highest value was shown by a single V butt joint with a value of 0.0756 Joule/ and the lowest impact value was shown by a double V butt joint with a value of 0.0145 Joule/ .
