尾梁

The old count's horse, a sorrel gelding, with a white mane and tail, called Viflyanka, was led by the count's groom; he was himself to drive straight in a light gig to the spot fixed for him to stand.

伯爵的马夫牵着老伯爵骑的一匹叫做维夫梁卡的白鬃白尾的枣红色骟马；他本人乘坐一辆轻便马车径直地向兽径驰去。

Based on finite element analysis software ANSYS,and according to the forms and characteristics of load on steel structure of tripper of stacker/reclaimer,topological optimization is made to the simplified steel structure of tripper,and optimum layout of auxiliary inclined arm is obtained,with the main body frame of steel structure of tripper determined.

基于有限元分析软件ANSYS，根据堆取料机尾车钢结构承载的形式与特点，对简化的尾车钢结构进行拓朴优化，得到了尾车钢结构在主体框架确定情况下辅助斜梁的最佳布置形式。

Then it uses beam unit to analyze and calculate the simplified tripper steel structure model,compares the pre and post optimization models stress,displacem...

然后利用梁单元对简化的空间尾车钢结构模型进行有限元静力和模态分析计算，对优化前后2种模型的应力、位移、重量及基频进行了比较，从而进一步验证了对尾车钢结构进行拓朴优化的可行性和优化结果的合理性。

The thrust coefficients and propulsive efficiency of a two-dimensional flexible fin with heaving and pitching motion were computed using FLUENT. The effect of different locations of the pitching axis on propulsive performance was examined using three deflexion modes which are respectively, modified Bose mode, cantilever beam with uniformly distributed load and cantilever beam with non-uniformly distributed load.

利用FLUENT软件数值计算了二维柔性鳍作升沉纵摇运动时的推力系数及推进效率，探讨了修正Bose变形方程、均匀载荷和非均匀载荷悬臂梁变形方程等三种柔性模式下纵摇轴位置对摆动鳍推进性能的影响，其中纵摇轴在尾缘处能够获得更大的推力，而最高的推进效率分别对应修正Bose模式下纵摇轴距首缘1/3弦长处和悬臂梁柔性变形模型下纵摇轴距首缘2/3弦长处。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
