Gross modifications in structural dynamics via interpolated modes

Gross modifications in structural dynamics via interpolated modes
Gross modifications in structural dynamics via interpolated modes
Repeated analysis of a structure for a range of parameter values is often encountered in engineering design and potimisation. In this paper, the problem of approximately predicting the natural frequencies of a system, when parameters undergo gross changes, is addressed. A method of 'interpolated modes' is developed. It is shown that reasonable estimates of the natural frequencies are obtained without a recourse to exact calculations for each value of the system parameter. Illustrative examples are given.

Abstract

Repeated analysis of a structure for a range of parameter values is often encountered in engineering design and potimisation. In this paper, the problem of approximately predicting the natural frequencies of a system, when parameters undergo gross changes, is addressed. A method of 'interpolated modes' is developed. It is shown that reasonable estimates of the natural frequencies are obtained without a recourse to exact calculations for each value of the system parameter. Illustrative examples are given.
