Abstract

Saat ini penggunaan 3D printing sangat bervariasi bahkan dalam aplikasi di moda transportasi yaitu sepeda. Sepeda balance bike merupakan sepeda yang digunakan sebagai media belajar anak – anak untuk melatih keseimbangan bersepeda. Steering sepeda merupakan komponen penting dimana bagian tersebut berperan sebagai sistem kemudi dan kestabilan sepeda. Selain itu filamen carbon-fiber nylon sangat sesuai karena memiliki sifat kuat dan ringan. Bentuk geometri steering juga berpengaruh karena akan dilakukan simulasi untuk memperoleh hasil yang optimal. Geometri yang divariasikan ialah Geometri A, Geometri B, dan Geometri C. Hasil simulasi statis menunjukkan bahwa variasi geometri B secara umum memiliki hasil simulasi statis yang paling baik dengan total deformasi sebesar 0,00349 m, tegangan maksimal sebesar 4,88 Mpa, dan regangan elastis sebesar 0,00461 m/m. Selain itu dalam analisis bobot, variasi geometri B memiliki bobot yang paling ringan. Dalam analisis survei yang dilakukan menunjukkan bahwa geometri B memiliki minat terbanyak sehingga pada analisis penentuan desain ditentukan bahwa geometri B sebagai objek yang akan dicetak. Parameter cetak yang digunakan antara lain shell, infill, speed, travel, flow, dan print support. Setelah ditimbang menggunakan neraca massa, hasil cetak steering geometri B memiliki bobot sebesar 760 gram. ==================================================================================================================== Right now the usage of 3D printing are vary even in the application in transportation such as bicycle. Balance bike is a type of a bike which used to train the children to polish their balance while riding. The steering of a bike is an important part where this part act as a main control system of the bicycle. Beside that, the carbon-fiber nylon filament is very suitable because of its good strength and lightweightness. To be able to become a good design, the geometry design will also take part because the geometry will undergo simulation to achieve optimal strength. The variation of the geometry which used are Geometry A, Geometry B, and Geometry C. The results of the static simulation shows that variation of the geometry B generally have the best static simulation results with total deformation of 0,00349 m, maksimum stress of 4,88 Mpa, and elastic strain of 0,00461 m/m. Then in the weight analysis the geometry B has the most lightweight. In the survey analysis which already done proves that geometry B has the biggest choice so that from the design analysis conclude that this research would use geometry B as the printed object. The printing parameters which would be use are shell, infill, speed, travel, flow, and print support. After being scaled by the mass scale, steering geometry B has the weight of 760 grams.
