摘要

The objective of this project was to establish the feasibility of determining the crevice gap between steam generator tubes and support plates by inducing and measuring tube vibratory motion. The project involved analysis and testing of the technique, with a single-tube multiple-support laboratory rig capable of simulating a variety of field conditions including a range of gap clearances, misalignments between the tubes and supports, and various boundary conditions at adjacent supports. The vibration techniques provided accurate measurement of gap clearances ranging from 1 to 30 mils.
