风力发电机转子支架焊缝残余应力的实验研究

Experiment Research on Residual Stress in the Welding Line of Fed Wind Generator Rotor Bracket

应用电测盲孔法对风力发电机转子支架退火前后焊接区残余应力进行了测试,得到了风力发电机转子支架焊接区退火前后残余应力的分布和变化规律,验证了风力发电机转子支架热处理工艺的处理效果,为兆瓦级发电机构件焊接、退火等加工工艺的分析评价及其服役期间的质量监控和分析,提供了第一手的实验数据。

Taking a series of tests on the welding residual stress of wind generator rotor bracket by applying electrical measurement of blind hole method,we got the distribution and variation of welding zone before and after annealing,verified the disposal effect of technology for heating processing for wind power generator rotor bracket,for MW generator machining technics such as component welding、annealing analysis evaluation and the quality control and analysis in the service,offered the first-hand data.
