The Critical Excitation of Nonlinear Systems

Journal of Applied Mechanics, 1977
The critical excitation of a mechanical system, in the terminology of this paper, is one that drives the system to a larger response peak than any other in some class of allowed excitations. The critical excitation is of interest in questions related to the reliability and safety because the magnitude of the response peak is frequently an indicator of ...

An Improved Critical Current Calculation Method of HTS Field-Excitation Coil for Double-Stator HTS Generator With Stationary Seal

IEEE transactions on energy conversion, 2023
In this article, a calculation method for critical current of high-temperature superconducting (HTS) excitation coils made by Bi-2223 tapes is proposed, which can provide a reference for the design and manufacture of HTS excitation coils.

Optimal damper placement for critical excitation

Probabilistic Engineering Mechanics, 2000
Since earthquake ground motions are very uncertain even with the present knowledge, it is desirable to develop a robust structural design method taking into account these uncertainties. Critical excitation approaches are promising and a new probabilistic critical excitation method is proposed. Different from the conventional critical excitation methods,

Critical excitation energy in fusion-evaporation reactions.

Physical Review C, 1990
The widths of the residue-mass distributions are used as a measure of the excitation energy of hot nuclei. They increase with the recoil velocity but saturate much below the calculated velocity {ital v}{sub CN} for complete fusion. Above these critical excitations energies (4.5--6.4 MeV/nucleon) derived from the recoil velocity, the normal evaporation ...
