Reduced Dynamic Modeling for Heavy-Duty Hydraulic Manipulators With Multi-Closed-Loop Mechanisms

open access: yesIEEE Access, 2020
A reduced dynamic modeling approach is introduced to systematically establish explicit closed-form dynamic equations for the main motion system of a heavy-duty hydraulic manipulator with multi-closed-loop mechanisms.

基于螺旋理论对少自由度并联机器人约束链的研究

open access: yesJixie chuandong, 2005
The screw theory is one of powerful tools for type synthesis and kinematics analysis of lower-mobility parallel mechanisms. The constraint problem is studied in this paper based on screw theory for some of the lower-mobility parallel mechanisms. The DOF

The Kinematics of a New Schönflies Motion Generator Parallel Manipulator Using Screw Theory

open access: yesMathematics
In this work, an innovative Schönflies motion generator manipulator is introduced, featuring a parallel architecture composed of serial chains with mixed degrees of freedom. Fundamental kinematic aspects essential to any manipulator such as displacement,

Dynamics analysis of pilot's upper limb manipulation process

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
A 6-degree-of-freedom (DOF) model of a pilot's upper limb is established in this study. A kinematics analysis is performed by using the screw theory and the product of exponential formula.

Mechanistic origin of high retained strength in refractory BCC high entropy alloys up to 1900K

open access: yes, 2019
The body centered cubic (BCC) high entropy alloys MoNbTaW and MoNbTaVW show exceptional strength retention up to 1900K. The mechanistic origin of the retained strength is unknown yet is crucial for finding the best alloys across the immense space of BCC ...

Interplay between electronic topology and crystal symmetry: Dislocation-line modes in topological band-insulators [PDF]

open access: yes, 2014
We elucidate the general rule governing the response of dislocation lines in three-dimensional topological band insulators. According to this ${\bf K}\text{-}{\bf b}\text{-}{\bf t}$ rule, the lattice topology, represented by dislocation lines oriented in
