Abstract
Recent research on soil dynamics and machine foundations has revealed that there are correct design principles for vibrating foundations which can be used without dependence on empirical methods. The most important discovery has been that any ground can oscillate at its own particular natural frequency, and machines and ground quite often vibrate in resonance. Stress waves, some with similar properties to light and sound waves, are of considerable and often of paramount importance, for their interaction can lead to structural failure. The authors have considered only steadily running machines and have merely indicated the mathematics, the designer being advised to consult the proper engineering text-books for a fuller account. They hope that the problem has not been over-simplified and that their conclusions may form a sound basis for future design practice.
