Firstly,the design parameters of forward sweep and positive bow were carried out separately for a transonic axial flow compressor rotor.

对一单级跨音轴流压气机中的动叶分别进行了前掠和正弯设计的参数研究,并根据研究得到的弯、掠动叶气动性能变化规律对动叶进行了前掠和正弯联合的三维设计,同时对动叶中部截面的叶型进行了二维设计以弥补弯掠动叶中部性能的降低。

Moment capacity of semi-rigid composite beam-column joints with flush end plate connections:Ⅱ. under positive moment;

平端板连接半刚性梁柱组合节点的抗弯承载力Ⅱ:正弯矩作用

In this paper,flush end-plate composite joints under positive moment were performed to investi- gate the behavior of composite joints with the H type steel column and partially encased composite column which were connected to steel beams by flush end plate and high strength bolts.

通过试验研究了端板连接钢-混凝土组合节点在正弯矩作用下的受力性能,对 H 型钢柱-压型钢板组合梁节点和部分外包组合柱-压型钢板组合梁节点进行了对比试验。

The flow fields were measured in the blade tip clearances of the cascade with the conventional straight and positive curved blade.

详细测量了常规直叶片与正弯叶片栅间隙内与上、下游流场，比较两套叶栅的实验结果发现：叶片正弯减小了叶顶后3／5轴向弦长范围内的横向压力梯度，并消除了上通道涡，因而大大削弱了泄漏流与瑞壁横流之间的相互干扰，相对漏气量与叶栅流动损失都显著降低。

In order to study the mechanical behavior and the loading capacity of the special structure under different combined actions of load,in this paper,the three-dimensional plate-shell element model is constructed through the finite element procedure ANSYS,analysing one segment of composite box beam s special shape intersection of Beiijing South Station Viaduct in positive bending region.

为了研究异型梁的受力和承载性能,通过有限元程序ANSYS建立板壳单元三维空间模型,对北京南站高架桥某联正弯矩区组合箱梁异型岔口进行分析,重点分析岔口处钢箱-混凝土结合梁受力性能,即钢箱梁在各种荷载工况下的应力和变形特征,弯扭耦合作用下异形岔口的受力,活载偏载作用下支座反力。
