 Abstract
The thickness of a stable and economical frame has been designed in order to reduce costs. Therefore, this study applied structural analysis and vibration analysis based on a comparison of the thicknesses of frames. Four types of frames (1mm, 2mm, 3mm, and 5mm) were modeled on a bicycle frame that has a length of 842mm, a width of 100mm, and a height of 400.5mm, and all of these frames generated the stress and maximum deformation amount in the state and around the saddle. The maximum stress shown was 25.732 MPa in 1mm, 11.79 MPa in 2mm, and 8.2015 MPa in 3mm, and the maximum deformation amount shown was 0.063611mm in 1mm, 0.031978mm in 2mm, and 0.022319mm in 3mm. The natural frequency of the frame thicknesses 1mm, 2mm, and 3mm was estimated as within 270 Hz. The critical frequency of conditions of 3mm was the biggest at 118.1Hz compared with the 3-mm model; thus, 3mm was shown to have the most satisfactory resistance.
