Vibration measurements, vibration protection, and structural dynamics have been an important part of GuD’s range of services since the day it was founded. This was mainly due to the traditionally close ties to the Institute of Geotechnical Engineering and Soil Mechanics at the Technical University of Berlin. Our measuring equipment, methods, and calculation procedures have been developed much further since then. Today GuD is in a position to process structural dynamic tasks of all types according to the latest state of the art, applying the expertise of their highly specialized staff and their very extensive range of instrumentation. The close cooperation with the related competence areas of geotechnics and soil engineering is of particular importance to the company.
The requirements for failsafe vibration reduction are often quite high in research institutes, in the semiconductor industry, and in optical manufacturing, as well as at other highly sensitive facilities. For example, the permitted vibration amplitudes in electron microscopy is several orders of magnitude lower than what a person could even perceive. To comply with the stated or to be determined vibration specifications, studies on the vibration input into the structure and about the vibration behavior of the support structure are required. Forecast calculations regarding the expected structural component vibrations in the locations of planned sensitive facilities have to be carried out. GuD’s expertises start with vibrations measured at the subsoil, taking into account the soil-structure-interaction and the planned construction. External vibrational excitations, e.g. from street and supplier traffic, as well as internal excitations emitted by the operation of room equipment, or vibrations caused by individuals are all considered. The effectiveness of vibration reducing or isolating measures can be investigated with structural dynamic models.
