Abstract

Fused Deposition Modelling banyak digunakan sebagai metode dalam pembuatan rapid prototyping dan salah satu yang dikembangkan adalah sepeda. Sepeda yang saat ini diminati yaitu balance bike yang memiliki manfaat untuk melatih keseimbangan anak sebagai dasar kemampuan dalam bersepeda. Salah satu bagian terpenting dalam sepeda yaitu frame, dimana penggunaan material carbon fiber-nylon dapat memenuhi sifat mekanik material yang dibutuhkan. Dilakukan analisis pengaruh variasi geometri yakni honeycomb, circle dan rhombus terhadap kekuatan dan bobot. Pendekatan analisis numerik digunakan untuk mengetahui pengaruh variasi geometri terhadap kekuatan dengan pengujian beban statis menggunakan software ANSYS sebesar 196,133 N. Hasil simulasi statis menunjukkan geometri honeycomb memiliki sifat mekanik paling baik dengan tegangan maksimal sebesar 5,5224 MPa, regangan elastis sebesar 0,0062933 m/m dan deformasi total sebesar 0,00035311 m. Aspek lain dalam penentuan desain adalah bobot dan survei estetika dimana geometri circle memiliki bobot paling ringan dan geometri honeycomb menjadi desain yang paling diminati oleh masyarakat. Proses pencetakan geometri honeycomb memakan waktu 1 hari 13 jam dengan menghabiskan 1725 gram filamen carbon fiber-nylon. Setelah ditimbang, frame honeycomb memiliki bobot sebesar 1050 gram. ================================================================================================================== Fused Deposition Modeling (FDM) is known as 3D printing is the most extensively used as a method in the making of rapid prototyping and one of the products which is recently being developed is bicycles. Bicycles that are now in demand are balance bikes which encourage kids to train their balance as a basic skill in cycling. One of the important parts of a bicycle is the frame, where the use of carbon fiber-nylon material can meet the required mechanical properties of the material. This research aims to analyze the effect of geometric design variations; honeycomb, circle, and rhombus on strength and weight of 3D printed Balance Bike frame. The numerical analysis approach was used to determine the effect of geometric variations in strength by static load testing using ANSYS with 196,133 N load. The static simulation showed honeycomb geometry has the best material mechanical properties with equivalent stress of 5,5224 MPa, equivalent elastic strain of 0,0062933 m/m, and total deformation of 0,00035311 m. Besides mechanical properties, weight analysis and aesthetic surveys were considered to determine the geometric design, which showed circle geometry has the lightest weight and honeycomb geometry is the most sought after design by the survey participant. Geometric honeycomb printing takes 1 day 13 hours by consuming 1725 grams of carbon fiber-nylon filament. After being weighed using a mass balance, frame honeycomb is 1050 grams in total weight.
