Analyse d'une loi de mouvement en jerk sur le comportement vibratoire d'une structure mécanique. Application à la commande d'axe en translation

This paper deals with the specific influence of the jerk value on the behaviour of industrial high-spee systems. The physical relationships between the jerk maximum value, the vibratory level reached and the effective movement time are formalised on a axis-drive model taking account of the main control parameters and effects of a predominating deformation mode. Experimental tests conducted on three test-setups with different architectures and characteristics demonstrate the effectiveness of the suggested approach in estimating the evolution of the maximum residual oscillations.
