design of structures and foundations for vibrating
2015-12-1 foundations subjected to vibratory loads. The design of a machine foundation is generally made by idealizing the foundation- soil system as spring-mass dashpot model having one or two degrees of freedom. Most machine foundations are treated as surface footing and the soil spring and damping values are determined using the elastic-half space analog.

Machine Foundation - Types, Advantages And Uses
The general principles of machine foundation design are as follows: 1. It should be isolated from the adjoining parts of the building by leaving a gap around it to avoid the transmission of vibrations. The gap is filled with suitable insulators or dampers. 2. The foundation should be stiff and rigid to avoid possibilities of tilt in it. 3.

vibrating machine foundation design recommendation
2019-1-21 There was only one that emphasized that it was vitally important the "width" of the foundation slab should be something like 2X the height of the shaft CL above the foundation, and sometimes much wider if the soil is poor. And of course the thickness of the foundation must be sufficient for all the imposed forces.

Machine foundations and their vibration analysis
2021-3-13 The part of the soil below the foundation which vibrates due to the machine vibrations is called as the in-phase soil mass. Hence the total mass (m) can be shown as: m = mf + ms Where, m- total mass, m f – mass of foundation m s – in-phase soil mass The in-phase soil mass varies from 0 to m f, hence the total mass varies from m f to m s

In particular for rotating machinery, such as pumps, blowers or turbines, a knowledge of the vibrational characteristics of a foundation is of great importance [l], [2]. In this chapter, the principles of the design of a foundation subject to dynamic loading are introduced and discussed with reference to simple mass-spring systems.
