The article presents model issues related to the study of vibration propagation phenomena in the adopted metro transport system. The assumed tasks can be carried out through operational or theoretical research. The process of modeling the dynamics of the object and the directions of research in the field of reducing the harmful impact of vibrations on engineering structures are presented.Research on vibrations occurring during the operation of a shallow metro is associated with technical and ergonomic problems. The first metro line and the planned second line will run through the center, through dense urban development.
Such a way of routing the line is associated with the following problems, which include:
a) The impact of metro operation on the vibrations of neighboring structures and the noise occurring in them, as well as on the people located in them, b) Durability and reliability of the vehicle-track-casing system, c) The impact of vibrations on a person located in a metro vehicle, determined by ride comfort and safety.
The designed second metro line in Warsaw will run through the city center with dense development, where the distances of buildings along the designed route are significantly less than 40 m (a value treated as the minimum for residential buildings). (…)
