Abstract: This paper aims to develop a software to analyse the influence of the variation of vehicle suspension angles. To do so, a model with 14 degrees of freedom was integrated with a graphical user interface that allows the user to define some parameters of the suspension and the environment. At the end of the work, it was possible to observe that the behaviour of caster bump for vehicles with different caster values is the same. Another conclusion that was already expected and validated the model and the software for this type of analysis is that when the left wheel of a suspension is excited, the load passed to the right side will be much greater if the suspension is dependent than if it is independent. The third and final analysis showed that the MacPherson strut has better responses than the double wishbone suspension when it comes to minimising bump effects.
