一米长叶片为东汽厂30万千瓦汽轮机的关键零件。其叶根型式采用直线枞树型,是一种新设计的叶根。为此,对其作了不少的试验研究工作,如有限元计算、光弹性试验、金属模型试验等。为了更进一步确保其安全性,确认其最终的极限承载能力,最后还进行了全尺寸的实物叶根试验。但本文只介绍 One meter long blade for the East Gas Factory 300,000 kilowatts turbine key components. Its leaf root type is linear fir, a newly designed leaf root. To this end, made a lot of experimental work, such as finite element calculation, photoelastic test, metal model test. In order to further ensure its safety, to confirm its ultimate ultimate carrying capacity, finally carried out full-size physical leaf root test. But this article only describes
