Abstract
In modern technology, the protection of mechanical objects from vibrational effects is an important problem. The task of increasing the efficiency of a vibration–isolation system as applied to vehicles is discussed. Operator equations that describe the movement of a single-mass system for active vibration isolation with a controllable magnetorheological damper are presented. A mathematical model of a closed system with negative feedback with respect to the vibration acceleration of the protected object in the form of a block diagram is considered. A controller that provides a decrease in the vibration accelerations of the protected object within a certain frequency range to a preset level is created. The possibility of simplifying the controller without substantial losses in control quality is substantiated by comparing the dynamic characteristics of the system. On the basis of a computer simulation, the dynamic characteristics of the open- and closed-loop systems for a harmonic disturbance were investigated taking the mass of the vibroprotected object into account. The description of the developed experimental bench for investigating the dynamic characteristics of the vibration–isolation system is given. The frequency characteristics of the active vibration–isolation system were studied. Comparison of the calculated and experimental data testifies to the effectiveness of the developed models and the adopted assumptions. The possibility fundamentally improving the quality of a vibration–isolation system when using the created system is shown.
