Effects of asymmetric stiffness on parametric instabilities of rotor
This work deals with effects of asymmetric stiffness on the dynamic behaviour of the rotor system. The analysis is presented through an extended Lagrangian Hamiltonian mechanics on the asymmetric rotor system, where symmetries are broken in terms of the rotor stiffness. The complete dynamics of asymmetries of rotor system is investigated with a case study. In this work, a mathematical model is ...
متن کاملSemiclassical scattering on conical intersections.
We apply a semiclassical approach to the scattering problem of a vibrational wave packet in the vicinity of a conical intersection of electronic energy surfaces and derive analytical expressions for the scattering matrix. The latter are valid when the scattering length that scales as square root(h) is small and a wave packet passes through the scattering region with a constant velocity. The ana...
متن کاملObservations on Transverse Instabilities
Machine studies have been conducted in the SPS to better characterise the transverse instabilities observed on the LHC beam by the beam induced electron cloud. Most of the observations have been performed at injection energy. Different beam configurations have been considered as a function of their availability from the injectors. The results of these observations (bunch centroid motion, head-t...

متن کاملAxisymmetric wave propagation on a conical shell
Equations are derived to describe the propagation of axially symmetric waves generated at the apex of a conical shell, taking into account he coupling between longitudinal and transverse waves. A form of approximate solution is proposed, based upon the Green's function for wave propagation on a fiat plate but containing several variational parameters, the number of which can be reduced to one i...
