Abstract

The focus of this paper is on the formalisation of the influence of a jerk-controlled movement law on the vibrations of industrial high-speed systems, i.e. systems for which axes are submitted to significant dynamical demands. Analysis of the physical relationship between the jerk limit and the maximum vibratory amplitude is conducted on a simplified axis drive model that simultaneously accounts for axis control parameters and predominant mode effects. Experimental measurements conducted on three tests-setups demonstrate the effectiveness of the proposed approach in accurately predicting the evolution of the vibration level according to the constant jerk stages time and the axis drive parameters.
