Estimation of Unmeasured DOF’s Using the Local Correspondence Principle

  • Conference paper
  • First Online:

Abstract

This paper will present a new method to estimate unmeasured Degrees of Freedom (DOF’s) in a structure using only a limited amount of sensors. The method applies the Locale Correspondence Principle (LCP) to estimate a linear transformation between experimentally determined mode shapes, and mode shapes from a Finite Element (FE) Model. Mode shapes from the FE model are then altered to fit the real mode shapes of the structure, creating a set of estimated mode shapes covering all nodes.

The method is easy to perform and has a wide variety of application within civil- and mechanical engineering.
