EXPERIMENTAL MODAL ANALYSIS OF 120kg SPOT WELDING ROBOTS

Abstract

Abstract: The Dynamic characteristics of two spot welding robots model A and model B are given out by the method of experimental modal analysis, and the lower order of natural frequencies of these two robots under two typical postures are obtained. Through the analysis of the modal characteristics of the robots under two postures, relative weaker parts of the robots are pointed out. It pointed out that the distribution of the mass and stiffness of the robots should be matched, which have great influences on the dynamic characteristics of the robots. The improving suggestion for the two robots is put forward.

Key words: Dynamic characteristic, Experimental modal analysis, Spot welding robot
