DYNAMICS AND VIBRATION: INDUSTRIAL IMPACT

Industrial operations such as pressing or forging are common sources of ground-borne vibration. HGC Engineering has often been retained by engineers to mitigate the impacts of such vibration. Finite Element Analysis techniques are useful for such situations, as accurate modeling can require an assessment of the properties of the vibration source, the transmission medium (the ground) and also the impacted building, a dificult problem for any other assessment method.

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 match the operating frequencies of the equipment. The dynamic amplification which can occur if the frequencies do coincide can lead to hazardous structural fatigue situations, or shorten the life of the equipment.

FEA techniques can also assess how the ground responds to vibration impact.
