The paper presents an active vibration control system based on low dynamic stiffness of suspension. Using a simple two degrees-of-freedom system a few basic concepts of lowering suspension dynamic stiffness are presented. Through reducing the dynamic component of force between the protected subsystem and remaining part of the system, considerable vibration suppression is achieved. Linear and nonlinear algorithms are proposed. In the case of nonlinear control algorithm, the sufficient link between the protected subsystem and the remaining part of the system necessary to change the position of the protected subsystem is maintained. Experiments described in the paper cover two different cases. In the first case, the suspension operated as the passive suspension, while in the second case, the active reduction system was included. The results are presented graphically.
