Analysis of Foundation Influence Caused by Mechanical Vibration

Abstract:

In order to study excessive foundation vibration produced by mechanical vibration, this paper firstly deduce displacement amplitude formula based on dynamics theory and a simplified 2DOF model consisting of machine and foundation underneath. Functional expression of dynamic magnification factor D and frequency ratio is put forward by assuming stiffness ratio and mass ratio of machine and foundation. Then compared with function graphs under different suppositions, we know how to roughly assess foundation influence produced by mechanical vibration and how to roughly design machine which make foundation be unaffected.
