point entity

4 . this thesis uses finite element method , and by selecting 3 - dimension eight nodes element , and takes advantage of ansys to stimulate the different main girders to verify the accuracy of theoretical methods above
数值分析法：本文利用大型有限元程序ansys ，选用八节点实体单元，分别对以上三种截面形式主梁进行模拟，以比较理论计算结果的准确性。
As the deformation caused by centrifugal force is beyond the small deformation range , the large deformation effect was also taken into account in the equation . two models are constructed , one is of shrouded blade and the other is of bladed disc . the static natural frequencies and dynamic frequencies ( under 3000rpm ) are calculated by the finite element method and cyclic symmetry technique
针对叶片的结构特点,采用适应较强的三维八节点实体单元模拟叶片,建立叶片运动微分方程;叶片?轮盘系统在高速旋转时,受到离心力作用,使叶片发生大变形,故在方程中考虑了几何大变形的问题;为研究叶根轮缘之间的接触状态,建立了考虑叶根?轮缘接触的有限元方程,利用拉格朗日增广算法来求解该方程,确定叶根轮缘之间的接触面状态。
