Design and Construction of Mountain Bike Frame Using Solidworks Software and Matlab Simulink

Abstract

This paper discusses the application of generative design of mountain bike frames using Solidworks and MATLAB Simulink software. The topic is taken from the problem of the value of the inertial force that occurs in the mountain bike structure due to the dynamic force acting. The mountain bike in this study was made of epoxy carbon composite material in order to get a rigid, strong and light frame. The process is carried out using Solidworks software and analysis using MATLAB Simulink software. This article is an explanation of the bicycle frame design process that occurs due to the assumption of a wavy track. Based on computational studies conducted on MATLAB Simulik, for a load of 90 kg it can be seen that a static load is 1659.1 N and a dynamic load is 36.78 N with a gravity of 9.8 N/m2. Based on the simulation on the track model, it is known that there is a factor of safety of 5.8 with a deflection of less than 1 mm (ie 0.126 mm). The frame of this bike is made of wet laminated composite material made of epoxy composite fiber. Modeling a bicycle frame and how it is used is a major factor in determining the deflection of a bicycle structure.
