The problem of vehicle-bridge interaction can be followed in the literature from the year 1849. It was induced by the collapse of the Chester Rail Bridge in England in the year 1847. At the early stage the analytical methods were applied. The development of computers brings the change in the approach to the used methods of solution. The Finite Element Methods and the Component Element Methods represent the revolution and qualitative jump in the development. The dynamic deflections and the values of dynamic coefficients are remarkable from the point of bridge designers. The analysis of dynamic coefficients on the frequency ratio of natural frequency of vehicle and natural frequency of a bridge and dependence of dynamic coefficients on the speed of vehicle motion are presented in this contribution.
