    Abstract

    Mechanical dynamic responses of resistance welding machine have a significant influence on weld quality and electrode service life, it must be considered when the real welding production is carried out or the welding process is simulated. The mathematical models for characterizing the mechanical dynamic responses are normally a few coupled differential equations which can be easily created according to the theories of kinematics and dynamics (such as Newton’s second law), however the problem is that the parameters contained in the equations are unknown and hard to be determined due to the complexities and differences of machine constructions. In this paper, a method of identifying the machine mechanical parameters based on the measured data is presented no matter how the machine construction and what types of machine are. The computations are implemented in MATLAB.
