Theoretical and Experimental Investigation of a Vibration Suppression Model for an Industrial Wood Planer

摘要

Theoretical and experimental investigations of a vibration suppression model used to simulate control of workpiece vibrations were carried out. The analytical model used to examine the effect of stiffness on vibration suppression employed a series of linear springs that supplied compressive forces over a finite contact length to the workpiece model, a slender, simply supported beam. The response of the simply supported beam to the stiffness loads was obtained by the derivation and solution of the governing differential equations of motion for the stiffness model. The mass characteristics of a suppressor system were obtained by replacing the linear springs used in the stiffness model with lumped masses. A result similar to the stiffness model response was obtained by the solution of the derived differential equation governing the motion of the mass model. Three workpiece models were used to verify and extend the analytical results. The materials chosen for the experimental suppressors were synthetic neoprene rubber, having low mass and stiffness per unit length, and steel, possessing high mass and stiffness per unit length. The authors conclude that high mass and stiffness characteristics of the suppressor models were quite desirable in a practical suppression system.
