As a heavy vehicle travels over an uneven road surface a complex dynamic interaction occurs which induces dynamic loads into the ground. The generated ground vibrations propagate outwards and can lead to discomfort and / or damage to nearby bystanders and structures. The research presented in this paper is focused on the development of a two-step numerical model to estimate the ground vibrations generated from a heavy vehicle travelling over a speed bump (or geometric obstacle). The first step employs a multibody system to model the heavy vehicle and simulate the dynamic interaction between the vehicle and the geometric obstacle, while the second step makes use of the finite element method to simulate the propagation of ground vibrations. The multibody model is used to produce a time-history of the dynamic loads (i.e. contact forces) generated at the tyre-pavement interface, which is then input into the finite element ground model. Validation of the approach is undertaken through a comparison with well-established experimental results. The influence of various parameters, such as vehicle speed and geometric properties of the obstacle, were investigated through a sensitivity analysis. The resulting model is flexible and can be used to evaluate numerous vehicle-obstacle combinations on the ground vibrations generated.
