Experimental Identification of Mechanical Structure with Characteristic Matrices : Part 1. Proposition and Basic Approach
Masaaki Ookuma, Akio NAGAMATU · Bulletin of JSME · 1985
A new method of experimental identification is proposed in which a stable solution is always obtained for the real numerical calculation. Identification means the construction of a mathematical model which explains the dynamic characteristics of a machine or a mechanical structure. There are two ways in identification, namely theoretical and experimental ones. And there are two types of the techniques for the experimental identification. One is the type called 'Curve fit' which can identify the model prameter. It has been studied by many reseachers. The other is the type which identifies 'Characteristic matrices'. But, there are not many published reports about these techniques which will be useful. In this report, a method of experimental identification of the characteristic matrices is explained, and an example of numerical simulation is given.
