Modal Parameter Analysis for Underdamped Mechanical System

Popis výsledku v původním jazyce

There are many ways to model and to analyze discrete event systems. In general these systems lead to a non-linear characteristic equation description in linear algebra. This paper presents an analytical method for solving the characteristic equation of higher order, which arise when solving ordinary differential equations of motion of rigid body systems with 2 LESS-THAN OR EQUAL TO po LESS-THAN OR EQUAL TO 10 degrees of freedom. The objective of this work was to express the characteristic equation in the form of product quadratic polynomial, from which the modal components could be found. To validate the model, the modal parameters extraction technique - Ibrahim Time Domain - was used to extract modal parameters from artificial data developed in MATLABenvironment. The extracted modal components were compared to those obtained from the analytical model.
