Computer analysis of a three mass crane dynamic system

Strong Soil vibrations can be intruding and leading on the extreme to damages. They are a reason for defects in delicate products of machinery and adverse effect on vibration sensitive instruments. In order to avoid such results, vibration amplitudes should be restricted to the limits specified in standards. Vibrations that exceed or are expected to exceed standard limits call for protective measures. In this work we consider design configurations that provide effective isolation against vibrations and in certain cases reduced differential settlements, using ground replacement by an elastic layer. Numerical examples using elastic layers, for example of 0.5 m thickness, result in effective vibration isolation within wide frequency range
