Dynamic Analysis of Reactor Internal Structures with Impact Between Components

Vibro-impact responses of a tube with tube--baffle interaction. [LMFBR]

“…This kind of technique was used by Bohn and Nahavandi [6]. Some numerical studies by Krleg and Key [17] showed that the errors introduced by the lamped mass-explicit method are cummulative.…”

Effect of tube-support interaction on the vibration of a tube on multiple supports

“…Natural Frequencies and Mode Shapes for "Support-. Several authors [3][4][5][6][7][8][9][10][11] have studied, theoretically and experimentally, to determine dynamic behavior of tubes with motion-limiting supports.…”

“…Not only are natural frequencies and damping important, the response amplitude of a tube is also important especially when there exists a potential for exciting a resonant mode at various operating levels less the:m full heat exchanger design flow [12]. Several investigators [6][7][8] have applied the finite element method to predict tube vibration by intraducing clearances and assuming linear elastic contact deformation between tube and supports. Chen et al [9] theoretically studied a force-excited beam supported at the ends, with a motion-limiting stop at the midpoint, and developed a solution method which involves determining the "gross"…”
