摘　　要：本文对现有盲孔法残余应力测试装置存在的问题进行了系统地分析,提出并设计了一套全新结构的盲孔法残余应力测试装置。该残余应力测试装置解决了水轮机转轮使用盲孔法测残余应力时存在盲区的问题。使用该套装置后比改进前的工作效率提高了三倍。In this paper, the problems existing in available measurement device of residual stress by blind hole method are analyzed in detail, and a set of new measurement device with new structure is devised. After the new device is used, blind area problem is resolved when residual stress for hydraulic turbine runner is measured. Working efficiency is three times higher than before.
