ABSTRACT:
Disclosed is a method for determining the behavior of jointly movable shafts of a multi-shaft machine. According to said method, a simulation model is created individually for each shaft. The shafts are then impinged upon individually by a movement pattern, and measurable variables are detected in order to be able to make a statement about the transformation of the movement pattern by the shaft. Especially the setpoint position and the actual position of the shafts are recorded (cf. figure). Simulation model parameters, e.g. the inert mass of the shaft, the friction or elasticity of the shaft, can be defined based upon an analysis of the detected measurable variables, whereupon a coordinated movement of at least two shafts can be simulated, the behavior of the individual shafts being considered independent from the behavior of the other shaft. A simulated trajectory is generated. A characteristic variable, e.g. the circularity deviation or the circular hysteresis, can be defined for the coordinated movement of the shafts.
