Analysis of the effect of geometry frame on the strength and weight of balance bike made by 3D printing
Abstract
Fused Deposition Modeling (FDM) is known as 3D printing is the most extensively used as a method in the making of rapid prototyping, 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 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.
