Dynamic loads, or non-static loads, are particularly used in mechanical engineering and construction. There are assumed to be a very large number of loadchanges (switching between loading and unloading, changes in loading direction or changes in load height) over the service life of the component. These load changes occur at anchorages with plugs, for instance on robots, cranes, and elevators. However, they also occur on trains passing by noise protection walls or trucks in road tunnels, which generate dynamic loads on installations due to the constant interchange between pressure and suction caused by airflow.
