As a foundation of SEA for consevatively or non-conservativelycoupled systems under correlative excitations,power flow and energy distribu-tion in two coupled osillators under proportionally correlative excitations arestudied mainly in this paper.Theoretical relationship among power flow andtime averaged vibational energy of the osillators,as well as power balance equa-tions and energy ratio or them,are derived.Further along,power flow,energydistribution and power balance equations of the systems in conservative ornon-conservative coupling and under proportional correlative excitations arediscussed in detail,with comparing with characteristics of those innon-correlative excitations.Numerical resu1ts supporting the basic theory aregiven,too.Results show that the power flow and energy distribution of theosillators under correlative excitations,either conservative or non-conservativecoupling,are much different to those in the condition of non-correlativeexcitations.
As a foundation of SEA for consevatively or non-conservatively coupled systems under correlative excitations, power flow and energy distribu tion in two coupled osillators under proportionally correlative excitations are staged primarily in this paper. Theoretical relationship among power flow and time averaged vibational energy of the osillators, as well as power balance equa-tions and energy ratio or them, are derived. Still along, power flow, energydistribution and power balance equations of the systems in conservative ornon-conservative coupling and under proportional correlative excitations arediscussed in detail, with comparing with characteristics of those innon-correlative excitations. Numerical resu1ts supporting the basic theory aregiven, too. Results show that the power flow and energy distribution of theosillators under correlative excitations, either conservative or non-conservative coupling, are much different to those in the condition of non- correlativeexcitations.
