Impact vibrations of guide thimbles in nuclear fuel assembly
Original language description
The guide thimbles (GT) in nuclear fuel assembly (FA) are beam-type continua embedded in spacer grid cells and sleeve (SL) with radial clearances. Spacer grid vibrations excited by pressure pulsations of the cooling liquid were investigated still on thelinearized FA global model. The aim of this paper is presentation of the original approach to mathematical modelling and simulation analysis of nonlinear GT impact vibrations respecting friction forces described with the "force-velocity-displacement" characteristics.
