Abstract

Abstract:

The tolerance analysis of China Fusion Engineering Test Reactor vacuum vessel is performed using the CETOL tolerance analysis software based on the CATIA platform. Based on the three-dimensional solid model, the assembled targets of the vacuum vessel are simplified and subdivided. Tolerances are assigned according to the overall assembly requirements of the vacuum vessel, and tolerance analysis models are established. The critical dimensions affecting the target tolerances have been determined through the sensitivity and contribution, and the unreasonable tolerances have been redistributed to meet the tolerance requirements of the component, which is very useful to ensure the assembly quality of the vacuum vessel.

Key words: China fusion engineering test reactor, Vacuum chamber, Tolerance analysis, Sensitivity, Contribution

摘要：

利用CATIA平台的CETOL公差分析软件对中国聚变工程实验堆(CFETR)真空室进行了公差分析，在三维实体模型的基础上对目标进行模型简化和剖分。根据真空室整体装配性要求对公差进行分配，建立公差分析模型。通过敏感度和贡献度分析，确定影响目标公差的关键尺寸，对不合理的公差进行重新分配，以达到满足目标尺寸的公差要求，确保真空室的制造及装配质量。
