The problem of reducing the level of vibrations in various constructions, especially in bridges, has been considered for a very long time. One possible solution is to use vibration absorbers. They are advantageous for a few reasons, including economy and simplicity of installation during operation phase. However, it is not easy to properly tune a Dynamic Vibration Absorber. This is a very important issue because a badly tuned DVA can increase vibrations instead of decreasing them. In bridges, this is extremely important, especially for users’ comfort. The paper focuses on the problem of optimising the cooperation between several dynamic vibration absorbers installed in a structure which is loaded with random traffic. The damped vibrations of a simply supported Euler–Bernoulli beam of finite length with few absorbers fitted at different points subjected to a sequence of moving forces with a constant velocity is considered. The stochastic properties of the load are modelled by means of a filtering Poisson process. The considered model consists of a set of single-degree-of-freedom absorbers with a multi-degree-of-freedom primary structure. The optimisation of the absorber’s parameters is achieved using an evolutionary algorithm.
