On the Dynamic Vibration Damped Absorber of the Vibration System
Transactions of the Japan Society of Mechanical Engineers, 1977 Main purpose of this paper is to analyse the forced vibration prevention of the vibration system with positive or negative damping by the damped dynamic absorber. The cases treated in this paper are: the case I (the alternative exciting force of a constant magnitude is acting on the mass of the main system), the case II (the alternative exciting force,

Fostering Innovation: Streamlining Magnetocaloric Materials Research by Digitalization
Advanced Engineering Materials, EarlyView.Magnetocaloric cooling (MCE) is an environmentally friendly refrigeration method with great potential. Optimizing MCE materials involves the preparation and screening of large quantities of samples, which in turn generates a large amount of data. A digitalization approach is presented that uses ontologies, knowledge graphs, and digital workflows to ...

Occurrence Mechanism and Suppression Method for Shudder in Automatic Transmission Powertrain
International Journal of Automotive Engineering, 2014 Shudder occasionally occurs in the lock-up clutch of automatic transmissions when the frictional characteristics of the lock-up clutch have a negative slope with respect to the relative slip velocity. This study evaluates the effect of a dynamic absorber

Adaptive Piezoelectric Absorber for Active Vibration Control
Actuators, 2016 Passive vibration control solutions are often limited to working reliably at one design point. Especially applied to lightweight structures, which tend to have unwanted vibration, active vibration control approaches can outperform passive solutions.
