CONTRIBUTIONS TO THE APPROXIMATION WITH POLYNOMIAL FUNCTIONS OF MATERIAL SYSTEMS VIBRATIONS. PART I: THEORETICAL CONSIDERATIONS ON THE REAL MECHANICAL SYSTEM
Abstract
Abstract: The paper presents the approximation of the graphic representations of the measured vibrations for a truck platform, through 10th degree polynomial functions. The approximation by interpolating Lagrange within four distinct measuring points is applied, using the Vandermonde matrix at each analyzed point. Approximation leads to truthful results, so it can be considered valid for the application of vibration analysis of material systems.
Key words: mechanical vibrations, 10th degree polynomial functions, mathematical approximation.
