Static Linear Stress Analysis of Road Bike Frame Design Using Finite Element Method

Abstract

This paper presented the stress analysis of road bike frame to investigate the strength and safety factor of road bike frame. Bicycle manufacturers must ensure the performance and comfort of the product to comply with applicable standards. Various factors should be considered to obtain a proper design of a bike and the stress within the structure is necessary to be studied to avoid crash. Experimental frame testing is quite expensive, therefore numerical methods such as FEM are currently applied to predict the performance of road bike frames. In this study, the Finite Element Method (FEM) was used to see the maximum stress from two types of road bike frame with linear static analysis. The loading cases used in this study consist of three different static loading cases with 100 kg rider weight. Static simulation results show the maximum von Mises stress value from the overall loading cases is 164.5 MPa for the type 1 frame and 123.9 MPa for the type 2 frame. The minimum safety factor value for the type 1 frame is 1.67 and 2.22 for the type 2 frame.
