Abstract

This paper proposes a mathematical correlation between styrene butadiene rubber (SBR)-butadiene rubber (BR) composition and hyperelastic model parameters for numerical studies in vehicle tire design. Experimental, numerical, and curve-fitting methods were employed in this research. Experimental tests were conducted using tensile tests for SBR-BR. The numerical study of the SBR-BR tensile test was carried out using several classic hyperelastic models. The best hyperelastic model was selected based on the smallest deviation between numerical and experimental results. Curve-fitting was done between the best hyperelastic model parameters and the compound to obtain a new correlation, and it was validated. This research shows that the neo-Hookean model with 6 % deviation is the most suitable for the SBR-BR, and the mathematical correlation for SBR-BR composition and C10 is linearly correlated. SBR60 %-BR40 % shows the optimum composition for non-pneumatic tires with the characteristic of maximum tensile strength 16.71 MPa, elongation 251 %, and 200 % modulus 13.04 MPa.

Abstract

3D Printing is the process of creating 3D objects from CAD models. 3D printing technology is used to make various objects ranging from toys to components on machines. The advantages of this method allow the manufacture of prototypes at low cost and shorter processing time than other methods. Reverse engineering is the process of analyzing existing products as a reference to design similar products by minimizing and increasing product advantages. With the reverse engineering method, the performance principle of a tool, object, or system can be done by analyzing its structure, function, and operation. The purpose of this research is to be able to redesign the 3D Printing Machine so that students and lecturers can transfer technology and maintain in the development of 3D Printing machines made by domestic children. The output in this study is a 3D Printing machine that can operate with an area of 500x500 mm. The results of this study include, 1). This Innova Big Print 3D Printing Machine can be developed and upgraded into a Reliable 3D Machine. 2).This 3D machine can be increased in speed from 60 mm/s to 120 mm/s, This has experienced a very significant increase. 3). This 3D Print machine can already transfer data using wifi so that it makes it easier in the printing process.

Abstract

One of the important components on a combat vehicle is the ground pad shoe (GPS) or track pad. GPS that has been developed at this time mostly uses rubber material. Rubber raw materials themselves are found in Indonesia in large amount. Indonesia left 3 million tonnes of natural rubber unprocessed in 2018. On the other hand, natural rubber research is quite expensive and takes a long time to become a product. To make rubber products is needed special molds and tests. To solve the high costs and long time involved in rubber research, it is necessary to carry out numerical research. In this study, a numerical study of GPS rubber for combat vehicles was carried out with a hyperelastic material model. The research was conducted experimentally and numerically. Tensile testing is carried out on imported GPS samples which are then used as comparison data for numerical studies. The Mooney-Rivlin, Neo-Hookean, Yeoh, and Ogden hyperelastic models were varied to get the stress and strain values ​​closest to the experimental test. The results of the numerical study show that the best hyperelastic model for the imported GPS rubber model is the Neo-Hookean model. The tensile strength of GPS according to the experimental tensile test results is 16.93 MPa, while the result of the finite element method (FEM) is 16.75 MPa. The GPS modulus 200% according to the experimental tensile test results is 14.7 mm/mm, while the FEM result is 15.3 mm/mm. The difference between the FEM and experimental test values ​​for tensile strength and modulus 200% are below 5%. Maximum stress on GPS is 4,4 MPa and safety factor 3,8.

Abstract

Perkembangan teknologi cetak tiga dimensi semakin pesat seiring dengan kebutuhan akan prototipe yang cepat di berbagai industri. Penelitian ini bertujuan untuk meningkatkan kecepatan cetak pada mesin 3D Print Innova melalui rekayasa ulang dengan mengimplementasikan teknologi Klipper. Klipper adalah firmware yang memungkinkan pengendalian motor yang lebih cepat dan efisien dengan memanfaatkan unit pemrosesan eksternal, sehingga dapat meningkatkan kecepatan cetak. Metode yang digunakan mengacu pada metode Pahl and Beitz, yang meliputi identifikasi kebutuhan, perancangan konsep, perancangan rinci, hingga tahap pengujian. Langkah-langkah tersebut mencakup analisis sistem mekanik dan elektronik yang ada, pemasangan perangkat keras tambahan, serta konfigurasi perangkat lunak Klipper untuk mengoptimalkan kecepatan pencetakan. Uji coba dilakukan untuk mengukur peningkatan kecepatan cetak dengan membandingkan waktu yang dibutuhkan untuk mencetak model yang sama sebelum dan sesudah implementasi Klipper. Teknologi Klipper terbukti mampu mereduksi waktu cetak hingga 71,2%. Selain itu, sistem yang dihasilkan menjadi lebih fleksibel dan mudah dikustomisasi. Penelitian ini diharapkan dapat menjadi acuan dalam optimalisasi kecepatan cetak pada mesin cetak 3D, khususnya melalui penerapan teknologi open-source seperti Klipper untuk mendukung proses manufaktur yang lebih cepat dan efisien.
