中文摘要:

某反应器转轮由超静定支架支撑，无法用理论方法进行受力计算及分析。为了确保其安全性，对受力杆件进行了现场应力测试，测量数据重复性较好，可信度较高。在此基础上，研究和分析了该超静定支架中受力杆件的应力、应变情况及其变化规律，确认了该反应器转轮系统强度及其安全系数足够；提出了在强度校核时必须考虑疲劳强度问题及改善加工和安装精度以提高系统的安全性。

英文摘要:

The runner of a reactor is supported by a statically indeterminate support, the stress of which could not be calculated and analyzed by theoretical methods. In order to ensure its security, the strain of the stressed component was tested on the spot. Through the analysis of the test data. it was found that the test data was of good repeatability and high reliability. By analyzing the strain and stress of the stressed component in the statically indeterminate support its variation law was found. The strength and safety factor of the runner system were considered to be adequate. To improve the safety measures of the system, the fatigue strength should be considered when the strength was checking and the machining and installation accuracy should be improved.
