Análisis comparativo de la frecuencia de oscilación, amplitud de vibración y coeficiente de amortiguamiento entre el sistema de suspensión trasera original y una suspensión trasera tipo push rod categoría M1 utilizando Matlab

Abstract

This study presents the analysis of a push rod suspension for M1 category vehicles, using Matlab as the main simulation and calculation tool. The design and dynamic evaluation of the system is addressed, focusing on fundamental parameters such as oscillation frequency, vibration amplitude and damping coefficient. These variables are essential to optimize the suspension and minimize vibrations during vehicle operation. The digitalization of the process not only facilitates obtaining an accurate suspension geometry for the suspension system, but also allows its behavior to be analyzed under two scenarios according to the physics of the mass-spring system in damped forced vibrations. This ensures that the most effective configurations are identified to improve stability and comfort. The tests include both theoretical and practical analysis, evaluating the performance of the system before and after implementing adjustments, ensuring that the results are applicable to real scenarios. Finally, the calculations performed during the analysis are attached, providing a solid technical basis to validate the suspension performance. These calculations have been verified in previous studies of M1 category passenger vehicles, confirming the usefulness of the approach presented in this work.
