Abstract
The article dwells upon the study of the properties of a passive vibration isolation system with a nonlinear characteristic of a controlled damper. The existing problems in the field of research and the objectives of the research are indicated. As an actuator, a magnetorheological vibration damper is used, the design of which is similar to serial samples. The design diagram of an oscillatory system with a nonlinear element of viscous resistance is presented. The characteristics of the nonlinear element depend on the linear speed of the damper piston as well as on the control current. To study the characteristics of the vibration isolation system, the MATLAB program was used. With the help of a special block of two variables for the specified program, a simulation model of the damper is set, based on which a simulation model of the vibration isolation system is built. The mechanism of formation for the damper nonlinear temporal characteristics is studied. Based on equivalent frequency characteristics, the dynamics of the vibration isolation system with the damper nonlinear and linearized characteristics is investigated. The calculation results are confirmed by experiments on the developed bench. The satisfactory adequacy of the developed model to the real vibration isolation system is shown. The obtained results are analyzed, and conclusions on the work done are formulated.
