A critical review of the cone model for analysis of machine foundations under translational and rotational motion
Abstract
ABSTRACT Analysis of dynamic behaviour of machine foundations is a challenging task. The prediction of dynamic behaviour can be done using a number of available techniques. In this paper, the suitability of the cone model, a strength of material approach, for predicting the foundation response under dynamic excitation is discussed. The governing equations for dynamic stiffness coefficients, i.e. spring coefficients and damping coefficients are presented for different modes of vibration for surface foundation on both homogeneous half space and two layered soil. The results obtained from the cone model are compared with existing results. It is found that the dynamic impedance functions can be computed accurately by knowing the soil properties underneath the machine foundation and the excitation frequency.
