摘要
Abstract
Based on metal-to-metal contact theory,it makes a detailed analysis on the screw preload determination for steam generator in PWR nuclear power plant. By use of finite element calculation and analysis,a preload-elongation curve was obtained. Finally,it provides a method on determining proper elongation for steam generator screw.关键词
