An intrinsic sufficient condition for regular decoupling

This paper introduces an intrinsic regularity property, namely, regular invertibility, which requires that a sequence of vector spaces has constant dimension after a certain order, thus allowing some degeneracies in the beginning. It corresponds to the system and its tangent having the same defect. Using the constant rank theorem, this property is shown to be sufficient condition for regular decoupling.

Analysis of the dynamic stress of planar flexible-links parallel robots

This paper presents a method for the dynamic stress analysis of planar parallel robots with flexible links and a rigid moving platform. The finite element-based dynamic model of flexible parallel robots is proposed. The relation between elastic deformations and elastic displacements of the flexible links is investigated, considering the coupling effects of elastic motion and rigid motion. The elastic deformations of links are calculated. Considering the effects of bending-shearing strain and tensile-compression strain, the dynamic stress of the links and its position are derived by using the Kineto-Elastodynamics theory and the Timoshenko beam theory. Due to the flexibility of the links, the dynamic stresses are well illustrated through numerical simulation. Compared with the results of the finite element software SAMCEF, the numerical simulation results show the good coherence and advantages of the analysis method. The dynamic stress analysis is demonstrated to have a significant impact on the analysis, design and control of flexible parallel robots.

考虑结构面退化的岩质边坡地震永久位移研究

针对岩质边坡平面滑动问题和楔形体滑动问题,提出了一种考虑结构面退化的岩质边坡的地震永久位移算法,提供了该法实施的流程,并用3个实例进行了说明。计算结果和前人的计算结果进行了对比,发现该法与试验计算结果吻合较好,能很好的估计边坡地震永久位移量值。传统Newmark法不考虑结构面退化,计算结果一般过低的估计了边坡地震永久位移量值,它较为适合估计地震永久位移量值较小的边坡。
