“…However, complex drive systems of motor vehicles, such as diesel-electric (hybrid) drives, on the one hand improve the energy efficiency of the source and reduce the emission of harmful exhaust components, but on the other hand, they can generate an increased level of torsional vibrations in the wheel drive system. For this reason, these systems are now attracting increasing interest from researchers in the field of the control and optimization of the torsional vibration level [15]. The phenomena accompanying torsional vibrations of crankshafts drew particular attention for the first time in the shipbuilding industry in the 1920s.…”

The problem of damping torsional vibrations of the crankshaft of a multi-cylinder engine is very important from the point of view of the durability and operational reliability of the drive unit. Over the years, attempts have been made to eliminate these vibrations and the phenomena accompanying them using various methods. One of the methods that effectively increases the durability and reliability of the drive unit is the use of a torsional vibration damper. The torsional vibration damper is designed and selected individually for a given drive system. A well-selected damper reduces the amplitude of the torsional vibrations of the shaft in the entire operating speed range of the engine. This paper proposes a thermo-hydrodynamic model of a viscous torsional vibration damper that enables the determination of the correct operating temperature range of the damper. The input parameters for the model, in particular the angular velocities of the damper elements as well as the geometric and mass dimensions of the damper were determined on a test stand equipped with a six-cylinder diesel engine equipped with a factory torsional vibration damper. The damper surface operating temperatures used in model verification were measured with a laser pyrometer. The presented comparative analysis of the results obtained numerically (theoretically) and the results obtained experimentally allow us to conclude that the proposed damper model gives an appropriate approximation to reality and can be used in the process of selecting a damper for the drive unit.

“…This allows the same basic model to be used for both forward-facing and backward-facing simulations depending on the inputs given [54]. Acausal models tend to be slightly more complex and time-consuming to develop and validate, but there are a number of software packages such as openModelica [54,55], Dymola [52,53,65], Simscape Driveline [52], and AMESim [66][67][68] which are available with pre-defined interfaces, component models, and even example systems to alleviate this issue. The major advantage of this type of model is that systems and components can be re-used much more readily and for many different purposes.…”

Due to environmental pollution concerns, emission regulations on internal combustion engines (ICEs) have been tightening and the importance of fuel efficiency has become pronounced. Thereupon, downsizing, downspeeding, turbo supercharging, and cylinder deactivation techniques have been implemented in designing modern ICEs. Despite their considerable benefits, these methods result in boosted torsional oscillations necessitating new vibration isolation technologies due to the limited performance of passive torsional vibration dampers. In addition, trade-offs are indispensable in the passive damper system designs since different engine operating points demand different values of oscillation attenuation parameters. Thus, this study was initiated to develop a novel active torsional vibration damper (ATVD) to attenuate the torsional vibrations of all engine operating points without making any trade-off and to open up a new comfort zone for the development of modern ICEs. Proposed ATVD is essentially a parametrically excited system that adjusts the stiffness rate, damping rate, and moment of inertia in accordance with a fuzzy logic control (FLC) law to maximize engine-borne torsional vibration attenuation capability. The ATVD performance is evaluated in a co-simulation environment by using a driving cycle with six engine operating points and its advantages over conventional passive dampers are demonstrated.
