Vibrating mechanical systems modeling for the purpose multidimensional power flow analysis from energy point of view utilizing of power flow paths theory

Project start:	01.01.2006
Project end:	31.12.2008
Programme:	VEGA
Project number:	2/6169/27
Institute position in the project:	The only one project investigator
Project leader:	Erich Wiszt

The scientific project interlocks the actually ending project VEGA "Power flow path and energy transfer in mechanical systems". Besides already gained models improvement and finished theory extension, their application in the next fields are supposed: a) a noise control – by using of the results for the method (or theory ) statistical energy analysis (the specification noise spreading path and their power signification ), b) a vibration control – by applying the results for active vibro-isolation for vehicles respectively for their models (one quarter, half etc.), c) a contribution to general understanding and using high-frequency excitation – application of the results for studying an influence of fast harmonic excitation to continuous system dynamics with inner damping (fast exciting effect to ”slow movement” includes so-called ”vibration force”). The project expands the range of knowledge about energy dispersion and flow of cross axis symmetrical elastic waves in anisotropic thick wall laminated interning cylinders in exploitation of already gained results in the case of three-layers transtropic-isotropic-transtropic cylinder. An actualization of existing software is supposed as well as experimental verification of calculated values of dispersion and power parameters in the cooperation with external foreign partner.
