RECEPTION THEORY AND SCHOOL RECEPTION
Hum, 2015 Using reception theory comprehensions, studying regularities of the literary work aesthetic reception in literature teaching as a complex emotional, imaginative and fantasy process which happens in the encounter of a student and literary work and which is influenced by a wide specter of interdisciplinary encounters, contemporary teaching methods in ...

Shock and Vibration, Volume 2024, Issue 1, 2024.A method to deduce the characteristics of rail corrugation was developed and presented in this paper. It has been found that noise and vibration in the train vehicle were primarily contributed by rail corrugation and wheel polygonalisation. As the characteristics of wheel sets of a particular train can be assumed to be unchanged during a trip, rail ...

Influence of the rail dampers on the frequencydomain response of the rail
MATEC Web of Conferences, 2018 Rail dampers are mechanical devices mounted at both sides of the rail web aiming to reduce the vibration along the rail. In this way, a shorter length of the rail vibrates effectively and the rolling noise is less intense.

Shock and Vibration, Volume 2024, Issue 1, 2024.For large‐scale complex nonconservative systems such as high‐speed rolling stock, the rigid‐flex coupling simulation technique is one of the effective methods in reducing lateral vibration and dynamic load sensitivity. Since two uncertain influences of wheel spin dissipation are caused by wheelset yaw oscillations and alternative load path variation ...

Receptance-Based Partial Pole Assignment for Asymmetric Systems Using State-Feedback
Shock and Vibration, 2012 Many structures or machines interact with some internal nonconservative forces and present asymmetric systems in which the stiffness and damping matrices are asymmetric. Examples include friction-induced vibration and aeroelastic flutter.

Optimization and Tuning of Passive Tuned Mass Damper Embedded in Milling Tool for Chatter Mitigation
Journal of Manufacturing and Materials Processing, 2020 Milling tools with a large length–diameter ratio are widely applied in machining structural features with deep depth. However, their high dynamic flexibility gives rise to chatter vibrations, which results in poor surface finish, reduced productivity ...
