Static load test and load transfer mechanism study of squeezed branch and plate pile in collapsible loess foundation

As a special geological phenomenon, the character of collapsible loess foundation is collapsible when penetrated by water. This character leads to the soil losing load bearing capacity largely and may lead to foundation failure. Pile is a popular foundation used in collapsible loess. The squeezed branch and plate pile is a new type of pile developed in recent years and has not be used in a project before. In this paper three squeezed branch and plate piles are tested in collapsible loess after immersion processing. The results may be used for reference in similar construction project, and to provide theoretical references for de- signing of the squeezed branch and plate piles in engineering practice.     

基于有限元分析的纳米级微进给平台设计

设计了一种利用弹性铰链作为预紧机构、高精度滚动导轨作为导向机构的单PZT驱动的微进给平台。利用有限元方法对微进给平台的结构和静、动态特性进行了研究。在静态特性中着重分析了微进给平台的静态刚度,得出整个动平台的工作平面上的刚度分布图。在动态特性分析中着重研究了微进给平台的模态振型、固有频率和谐波激励响应,得出了激进给平台在动态激振力作用下的特性。最后分析了微进给平台工作平面上静态刚度和动态刚度变化很大的原因,并提出一些改进的措施。

Exact Computation of Parallel Robot''''s Generalized Inertia Matrix

According to the definition of the new hypothetical states which have obvious physical sig-nificance and are termed as no-gravity static and accelerated states, a method for exact computa-tion of the parallel robot's generalized inertia matrix is presented. Based on the matrix theory, the generalized inertia matrix of the parallel robot can be computed on the assumption that the robot is in these new hypothetical states respectively. The approach is demonstrated by the Delta robot as an example. Based on the principle of the virtual work, the inverse dynamics model of the robot is formulized after the kinematics analysis. Finally, a numerical example is given and the element dis-tribution of the Delta robot's inertia matrix in the workspace is studied. The method has computational advantage of numerical accuracy for the Delta robot and can be parallelized easily.
