| 摘 要： | 采用有限元方法对大型压力容器局部热处理畸变进行模拟,基于热处理最大畸变量,初步设计了工装的最佳尺寸,分析了不同直径和壁厚对筒体局部热处理畸变量的影响,得到了适用于不同筒体尺寸的最佳防畸变工装数量。结果表明,支撑台宽度0.2 m、支撑柱直径ø4 cm为最佳的防畸变工装尺寸。筒体的直径越大,热处理畸变量也越大;筒体壁厚越厚,热处理畸变量越小;防畸变工装数量越多,热处理畸变量越小。

| Abstract: | Local heat treatment distortion of large pressure vessel was simulated by finite element method. Based on the maximum distortion of heat treatment, the optimal size of anti-distortion tooling was preliminarily designed. The influence of different diameters and wall thicknesses on local heat treatment distortion of cylinder was analyzed, and the optimal number of anti-distortion tooling suitable for different cylinder sizes was obtained. The results show that 0.2 m of supporting platform width and ø4 cm of support column diameter are the best anti-distortion tooling dimensions. The larger cylinder diameter is, the larger heat treatment distortion is. The thicker cylinder wall is, the smaller heat treatment distortion is. The more the number of anti-distortion tooling, the smaller heat treatment distortion. |
