摘　　要：水电站机组运行过程中受力复杂多变,难以通过数值仿真等技术进行准确捕捉与计算预测,因此想了解机组受力情况,进行现场试验是最好、最直接的技术方法。对某电站机组上、下机架与定子机座进行力特性试验分析。通过开机、变负荷、停机试验等数据分析发现,机组各部件的最大应力值均在材料允许值范围之内,机组部件强度满足要求,不会形成安全运行的隐患。The operation process of the hydropower station unit is complex and changeable,so it is difficult to accurately capture and predict the stress of the unit through numerical simulation and other technologies.Therefore,a field test is the best and most direct technical method to understand the stress of the unit.The force characteristics of a power station unit’s upper and lower frames and stator frames are tested and analyzed.The data analysis of the startup,variable load and shutdown test shows that each unit component’s maximum stress value is within the material’s allowable value range.The strength of the unit parts meets the requirements and will not form a hidden danger to the safe operation.
