In this study we are going to analyze different cases of mechanical loads on the frame of a full-suspension mountain bike. Based on literature analysis and in accordance with testing and frame design standards, we will determine typical load cases. We will then use finite element simulations to examine the resulting stress and deformation states. By analyzing the most demanding load cases, we will identify the main causes for the formation of critical points. Based on the numerical analysis results, including identical boundary conditions, we will determine the most suitable method for conducting a laboratory test. This test will help us verify whether the simulation results match the experimental observations. With the addition of the the rear shock absorber, we will upgrade the static simulations to dynamic ones, while paying special attention to the influence of the loading frequency and suspension damping. With the help of a simplified one-dimensional finite element model, we will
evaluate the kinematic response of the frame structure. We will research critical load cases that cause local increases in stress, resulting in weak points where cracks occur. These cracks are the consequence of multiple loading scenarios. Both the loading frequency and damping coefficient influence the resulting stress and deformation states of the frame. A simplified analysis proves sufficient for describing kinematics, which can make the process of constructing the frame easier.
