Abstract:
For
identification of machine tool dynamical systems, the frequency
response method or the mechanical impedance test is applied
generally. Its application has got enough success. Now a new
identification theory and method for the machine tool dynamical
systems is proposed and studied by us. The experiments are
completed successfully. Our identification theory and method is
to obtain the frequency response data using the complete
frequency response testing technique at first. Through the curve
fitting calculation by micro-computer, the transfer matrix of
the system is identified. Using the state graphical method, from
the transfer matrix, the state space mathematical model of the
system is obtained at last.
