Abstract

Paper presents the method and experimental stand that allows to identify the spring-damping parameters of pads in the forced vibrations conditions. Evaluation of the accuracy of the identification method was conducted using sensitivity analysis of the spring-damping parameters to the errors of the measurements of experimental stand vibration. Examinations of the pads made of epoxide material proved that smallest errors of the pads parameters determination are obtained for the resonance frequencies of the experimental stand. 1 Introduction Fundamentals of the spring-damping parameters of the pads of plastic material identification used in machine foundation were presented first at Contact Mechanics'9
