- This technique also shows that it can simulate deformation effects constructed by other geometric primitives , such as ellipsoid and torus
另外，利用扩展的曲线几何约束变形方法，还可以模拟诸如椭球和圆环体的变形效果。 - Appraise the test scheme of dynamic consolidation of each test district before test and make optimization suggestions ; 4 . the grain - size distrilidation of the underlayer of dynamic consolidation has great on consumption of the energy i , the better the dynamic consolidation effect is ; 5 . the deformation effect of dynamic consolidation foundation is that not only the settlement deformation of foundation will decrease greatly after pounding , but residual settlement deformation in each test district are compared , it can be concluded that the deformation stability of foundation of the runway engineering of pu - dong airport can satisfy the design requirment through dynamic consolidation according to optimized test scheme . but the underlayer of dynamic consolidation should be made when pounding
论文的主要工作和研究认识如下： ( 1 )确定必要的强夯施工参数； ( 2 )对既有砂性土又有粘性土地基的最佳夯击次数的确定方法进行了探讨； ( 3 )对试验前各试验小区的强夯试验方案进行了评价，并提出了优化建议； ( 4 )强夯垫层材料的级配对夯击能的消耗有很大影响，级配好的垫层对夯击能的传递比级配差的垫层效果好； ( 5 )强夯地基的变形效应主要是指夯后地基不但沉降变形会大幅度降低，而且剩余沉降变形会缓慢地发生； ( 6 )在比较各试验小区的变形稳定性后，按照优化后的试验方案进行强夯处理，则浦东机场场道工程地基的变形稳定性能满足设计要求，但须在处理时施加强夯垫层。 - The foundatims of the runway engineering of pu - dong international airport that had been finished and used are applied as background of this dissertation . the examing results of the tests of single - point pounding , the change of the character of foundation soil after pounding and the observation results of settlement of simulation test to runway surface are deeply analyzed . meanwhile , the monitor informations of deformation and settlement of foundation soil after pounding are analyzed . based on the research results as above , the deformation effect of dynamic consolidation foundation and dynamic consolidation tests are studied deeply and some valuable conclusion are obtained . the main work and research results of this dissertation are as foulows : 1
本文以已竣工并投入使用的浦东国际机场场道工程地基为背景，深入分析了单点夯击试验测试结果、强夯前后地基土性状变化、道面模拟试验的沉降观测结果，并对强夯后的地基土沉降变形监测资料进行了分析。在此基础上，对强夯试验和强夯地基的变形效应进行了较为深入研究，得出了一些有益的结论。 - As a result , shifting of the fundamental frequencies and redistribution of stress in the blade base possibly cause failure of the blade . a three - dimensional finite element model of a blade and its fir - tree attachments have been constructed and analyzed with taking into account of contact nonlinearity in the attachments and large deformation effect of the blade . the geometry mismatch was introduced into the finite element model by defining gaps between two contact surfaces in the attachments
分析结果表明叶根误差发生的位置对叶片弯曲振型的固有频率影响较大,对扭转振型影响较小;误差的大小对叶片各阶固有频率影响均较小,但对叶根应力分布有影响;比较发现,在计算固有频率时,将叶片在叶根处简单地处理成固支位移边界是不合理的。 - 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。
