Stiffness Analysis of Cable-Driven Parallel Robots
The aim of this thesis is the stiffness analysis of cable-driven parallel robots. Cable-driven parallel robots have drawn considerable attention because of their unique abilities and advantages such as the large workspace, light weight of cable actuators, easy disassembly and transportation of the …

Cement Stabilized Crushed Stone Base Course Strength and Stiffness Analysis
… were performed to characterize the strength and stiffness of a test strip located in central Arkansas. The tests conducted were the Static Plate Load Test (StPT), unconfined compression strength, MOE, and Poisson’s ratio. The recommended design values for the 1993 AASTHO Guide, the structural …

An introduction to geometrically nonlinear finite element stiffness analysis using the incremental step and equilibrium methods
The derivation of the beam-column element matrices and development of the incremental step method and of the equilibrium method are abstracted from other authors. Emphasis is placed on the consistency of the assumptions and restrictions imposed upon the element and the two methods. Two algorithms …

Design of 3-DOF parallel manipulators for micro-motion applications
… movement of the manipulator and to improve the stiffness of the structure. As a result, both structures support 3-DOF, including one translation on the Z-axis and two rotations around the X and Y axes. The manipulator with redundancy is designed to prevent singularity and to improve stiffness. …
