ABSTRACT:
A foundation for a vibrating machine is disclosed. The foundation includes a frame-like stage plate made from longitudinally aligned girders and transversely aligned beams. The girders and beams are hollow and have cross-sections which are dimensioned so that an axial moment of inertia relative to a bending axis of each of the girders and beams is at least three times the value required to ensure the ability of the stage plate to support a given load. As a consequence a natural frequency of the vibration system, which system includes the vibrating machine and the foundation, closest to the operating speed of the vibrating machine differs from the operating speed of the machine by at least fifteen percent of the operating speed of the machine.
