TL;DR: In this paper, a hydrodynamic torque converter with a pump wheel, a turbine wheel, and a torsional vibration damper is considered, where the energy storage elements of the damper stages are substantially arranged on a common radius.
Abstract: A hydrodynamic torque converter having a pump wheel accommodated in a housing, a turbine wheel, which can be driven by the pump wheel, and a torsional vibration damper, where the torsional vibration damper has a damper input drive component and a damper output drive component, which can rotate to a limited degree with respect to the damper input drive component to oppose the action of at least two damper stages which are operatively connected in series and which each have at least one energy storage element, where the torsional vibration damper also has an intermediate damper component, which is arranged operatively between the damper stages and which directly or indirectly accommodates a vibration absorber, where the energy storage elements of the damper stages are substantially arranged on a common radius, where the vibration absorber is arranged adjacent to the torsional vibration damper in the axial dimension.

TL;DR: In this article, an electrical control signal is produced which takes into account several coefficients through the adjustment of potentiometers in a control circuit which continuously controls the damping characteristic curve of the shock and vibration absorber system.
Abstract: A mass such as a vehicle or craft, for example an aircraft, is cushioned against landing shocks and vibrations by an electronically controlled shock and vibration absorber system. For this purpose an electrical control signal is produced which takes into account several coefficients through the adjustment of potentiometers in a control circuit which continuously controls the damping characteristic curve of the shock and vibration absorber system.

TL;DR: In this article, the authors proposed a global-local approach to give approximate analytical so-called three-element and non-traditional dynamic vibration absorbers in the case of undamped primary structures.
Abstract: The dynamic vibration absorber (DVA) has attracted attention since its invention. This paper deals with the optimization problems of the standard DVA and two other models of DVA called three-element DVA and non-traditional DVA for damped primary structures. Unlike the standard configuration, the three-element DVA contains two spring elements in which one is connected to a dashpot in a series and the other is placed in parallel. Meanwhile the non-traditional DVA has a linear viscous damper connecting the absorber mass directly to the ground. There have been some studies on the design of three-element and non-traditional dynamic vibration absorbers in the case of undamped primary structures. These studies have shown that both three-element and non-traditional DVAs perform better than the standard DVA. When the primary structure is damped, there are very few studies on the three-element and non-traditional DVAs in the literature. This article proposes a global-local approach to give approximate analytical so...

TL;DR: In this article, a long, narrow flexible plate subjected to cyclic disturbances at the midsection is regulated by a linear motor at the boundary, where the feedback signal is the boundary displacement from an LVDT sensor.
