Opis:: The paper deals with the control design of semi-active seat suspension systems. A semi-active vibration control strategy basing on the inverse dynamics of a spring or damper element and a primary controller is studied. The optimisation procedure proposed in the paper makes it possible to calculate controller settings and these, in turn, to define vibroisolation properties of semi-active suspension systems.
W pracy przedstawiono sposób projektowania systemu sterowania semi-aktywnym układem zawieszenia siedziska. Analizowano algorytm sterowania semi-aktywnego, który bazuje na modelu odwrotnym elementu sprężystego lub tłumiącego oraz na kontrolerze głównym. Procedura optymalizacji zaproponowana w pracy dodatkowo wspomaga dobór nastaw regulatora, ktore to nastawy definiują właściwości wibroizolacyjne semi-aktywnego układu zawieszenia.

Opis:: Asymptotic stability of finite energy solutions to a fluid-structure interaction with a static interface in a bounded domain Ω ∈ Rⁿ, n = 2 is considered. It is shown that the undamped model subject to ”partial flatness” geometric condition on the in- terface produces solutions whose energy converges strongly to zero; while with a stress type feedback control applied on the interface of the structure, the model produces solutions whose energy is exponentially stable. An addition of a static damping on the interface produces solutions whose full norm in the phase space is exponentially stable. Without a static damping an interesting phenomenon occurs that steady state solutions (equilibria) might generate genuinely growing in time solutions. This is purely nonlinear phenomenon captured by newly developed techniques amenable to handle instability of steady state solutions arising from nonlinearity.

Opis:: The driving comfort of the vehicle is primarily determined by the design of the suspension system, which transmits the force between the vehicle and the ground. There are different types of vehicle suspension systems, including active suspension systems that provide significant benefits for ride comfort while driving. However, the existing active suspension systems have limited functions such as power, and also complex structure. To overcome the problem, the proper design of the active suspension system by considering its present limitations is essential. A well-designed active suspension system controls the load on the wheels under the resonance of the body structure and ensures driving comfort. It reduces the vibrational energy of the vehicle body caused by the excitation of the road while keeping the stability of the vehicle within an acceptable limit. For a proper design of the active suspension system, the road surface, the seat suspension, and the wheel load are the most important elements to consider. In this study, different types of vehicle suspension systems with their limitations have been thoroughly investigated. Many aspects of control and some of the essential practical considerations are also explored.

Opis:: Chatter in machining processes is strong dependent on the dynamic compliance behaviour of the machine tool and workpiece. The critical cutting depth where chatter occurs is in inverse proportion to the absolute value of the negative real part of the complex dynamic compliance response function of the machine tool. Therefore, while designing a machine tool, its dynamic behaviour should be investigated and optimized, e.g. by using the finite element method. If further design optimization are not possible, active damping system might help avoiding chatter of the machine tool. Active damping systems can compensate the dynamic displacements between tool centre point of the machine tool and workpiece by applying dynamically correlated external energ (e.g. compensation forces) onto the machine structure. Next to an explanation of the general idea and systemizatio of active damping systems, this paper gives examples of recent research activities in the field of active damping systems for machine tools of the Laboratory for Machine Tools and Production Engineering (WZL) of Aachen University, Germany. The main challenges while designing active damping systems for machine tools are carved out.
