When mechanical equipment is fixed rigidly to a building floor slab or ceiling, the vibrations formed by the mechanical equipment are transmitted into the structure. These vibrations can travel in solid building elements such as structural columns, beams, and floor slabs which is described as structure-borne noise.
To help eradicate these problems, resilient mounts should be implemented to isolate the vibrating equipment (and anything rigidly connected to it) from the surrounding structure.
Vibration isolation involves installing vibrating equipment such as on resilient materials such as isolation pads or steel springs.
The target is to select an appropriate resilient material that, when loaded, will provide a system natural frequency, or resonant frequency, at least one-third of the lowest driving frequency of the equipment.
Industrial operations such as pressing or forging are common sources of ground-borne vibration and a suitable solution may be required to mitigate the impacts of such vibration.
The large dynamic loads associated with many types of industrial equipment often result in substantial vibration transmitted into the structure. It can be critically important to ensure that the natural frequencies of the structural system do not coincide with the operating frequencies of the problematic equipment. If this problem is not addressed then structural fatigue situations can occur and may also shorten the life of the machinery.
