(16) to a vehicle wheel(s) (19) and a vibrational spring-mass system (22) in parallel with the drive train's force flow that forms a damper interacting with torsional vibrations in the drive train and whose energy exchange with the drive train takes place between the start-up element ...
ENERGY ABSORPTION CHARACTERISTICS AND VIBRATION CONTROL EFFECT OF SEMI-ACTIVE MASS DAMPER SYSTEM The energy absorption characteristics of mass damper systems in time domain were studied in this paper. The control performance of the semi-active mass dam... K Tamura,A Wada - 《Journal of Structural ...
Spring mass with damper With this system there are three elements that need to be modeled: the mass, spring, and damper. We can combine the equations for each of them to develop the resulting overall model of the system. At any particular time there is an overall force equation that must...
Potential benefits of a non-linear stiffness in an energy harvesting device The benefits of using a non-linear stiffness in an energy harvesting device comprising a mass–spring–damper system are investigated. Analysis based on th... R Ramlan,MJ Brennan,BR Mace,... - 《Nonlinear Dynamics》 ...
To eliminate this negative feature, it is proposed to connect shunt capacitors in parallel with the damper control coil. Then, the system can be tested experimentally in terms of current in the damper control coil, sprung mass, and the capacity of shunt capacitors in order to evaluate system ...
Structural simplicity is another advantage of this configuration. Cantilever beams and clamped-clamped beams are two most commonly used mono-stable structures for PEHs. The mono-stable PEHs can be described through a mass-spring vibration systems and their resonant frequency, fr, can be calculated ...
Total energy reported in GLSTAT (see *DATABASE_GLSTAT ) is the sum of ∙internal energy ∙kinetic energy ∙contact (sliding) energy ∙hourglass energy ∙system damping energy ∙rigidwall energy Spring and damper energy reported in the glstat file is the sum of internal energy of ...
A schematic of the mass damper system of track substructure with different track layers and elements adopted for the rheological model is shown in Fig.19. Ballast, capping and subgrade layers are considered as mass elements with stiffness and damping. For implementing SEAL and CWRC mixtures, railw...
Effect of time delay on the generation of oscillation in a single degree-of-freedom mass-spring-damper system by nonlinear velocity feedback The present paper investigates the effect of time delay in a particular type of single degree-of-freedom self-excited oscillator. The self-excited vibration...
