Dynamic simulation and analysis of bicycle frame using laplace transform and Matlab Simulink = Phân tích và mô phỏng động lực học khung xe đạp sử dụng phép biến đổi laplace và Matlab Simulink

Abstract

This article focused to the dynamic analysis of a bicycle frame including the simulation ofbthe acting dynamic forces and the structural analysis of the frame. The dynamic forces from the road acting on the frame are determined from the equation of motion of Multi Degree of Freedom (MDOF) systems with MATLAB and the byke is considered moving on road with sinusoidal profile. The paper presents the following problems: the relationship between sinusoidal road profile and dynamic forces, natural frequencies and dynamic behaviors of the frame. Based on the results, we can determine the dynamic characteristics of the frame to avoid resonance and strengthen weak regions of it.
