Estimation of fuzzy structure parameters for continuous junctions

C. Soize, K. Bjaoui

Abstract


Structural complexity plays a fundamental role in the response of a master structure coupled with complex substructures in the context of structural-acoustic systems. The mean response function calculated by the fuzzy structure theory with zero deviation coefficients represents the reference complex structure response. The calculation of the envelopes with nonzero deviation coefficients based on the use of a second-order Neumann series expansion and Chebychev's inequality is very efficient. A new cost allowing estimation of fuzzy structure parameters uses a procedure based on the statistical energy approach.
