    摘要:

    随着风电机组功率与叶轮直径的突破性增长,风电塔筒结构技术面临更高、更强的极限挑战。基于组合结构原理,提出一种新型“弧形钢板–混凝土–波纹钢板”复合筒壁结构。该结构由弧形钢板、混凝土、波纹钢板及T形加劲肋组成。为研究其轴压性能,设计6个模型试件并开展轴压试验,分析了钢板厚度、波纹钢板位置及高厚比等参数对受力性能的影响。试验结果表明:增加钢板厚度能有效提高试件极限承载力,钢板厚度为2.5mm的试件相较于1.5mm的试件,极限承载力提升幅度为24.89%;波纹钢板位于筒壁内侧的试件极限承载力为1407.50kN,较位于筒壁外侧的试件(极限承载力1150.90kN)提高了22.30%;试件高厚比越大,极限承载力越低,试件高度从450mm增加至900mm时,极限承载力由965.30kN下降至823.00kN,减小了14.74%。

    Abstract:

    With the breakthrough growth of wind turbine power and impeller diameter, wind turbine tower structure technology is facing higher and stronger limit challenges. Therefore, this paper proposes a new type of "curved steel plate-concrete-corrugated steel plate" composite cylinder wall structure based on the composite structure principle. The structure consists of curved steel plate, concrete, corrugated steel plate and T-shaped stiffening ribs. In order to study its axial compression performance, six model specimens were designed to carry out axial compression tests to investigate the effects of steel plate thickness, corrugated steel plate position, height-thickness ratio and other parameters on its stress performance. The test results show that: the thickness of steel plate can effectively improve the ultimate bearing capacity of the specimen, the specimen with the thickness of 2.5 mm compared with the specimen with the thickness of 1.5 mm, the ultimate bearing capacity is increased by 24.89%; the ultimate bearing capacity of the specimen with the corrugated steel plate on the inner side of the cylinder wall is 1 407.50 kN, which is increased by 22.30% compared with that with the specimen with the corrugated steel plate on the outside side of the cylinder wall of 1 150.90 kN; the ultimate bearing capacity of the specimen with the corrugated steel plate on the outer side of the cylinder wall is increased by 22.30%. The higher the height-to-thickness ratio of the specimen, the lower the ultimate load carrying capacity, the height of the specimen increases from 450 mm to 900 mm, the ultimate load carrying capacity decreases from 965.30 kN to 823.00 kN, which is a decrease of 14.74%.
