Research on Displacement Mode and Path Tracking Method of Square Combined Deployable Mechanism
Xibei Gongye Daxue Xuebao, 2019 The motion path of the developable mechanism can not only grasp whether the mechanism can move according to the expected law, but also provide theoretical support for motion control.

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

Development of Two-Way Self-Adaptive Gripper Using Differential Gear
Actuators, 2022 In this paper, a two-way self-adaptive gripper that has adaptability to external disturbance loads during linear opening/closing pinch actions and adaptability to encompass a variety of shapes during grasping using a single actuator is proposed, unlike ...

Enhanced Eshelby twist on thin wurtzite InP nanowires and measurement of local crystal rotation [PDF]
, 2011 We have performed a detailed study of the lattice distortions of InP wurtzite nanowires containing an axial screw dislocation. Eshelby predicted that this kind of system should show a crystal rotation due to the dislocation induced torque.

An Application of Screw Theory to the Jerk Analysis of a Two-Degrees-of-Freedom Parallel Wrist
Robotics, 2015 In this work the velocity, acceleration, and jerk analyses of a two-degrees-of-freedom parallel wrist are approached by means of the theory of screws. For the sake of completeness, the finite kinematics of the manipulator is also investigated.

Virtual and Physical Prototyping of Reconfigurable Parallel Mechanisms with Single Actuation
Applied Sciences, 2021 The paper presents novel models of reconfigurable parallel mechanisms (RPMs) with a single active degree-of-freedom (1-DOF). The mechanisms contain three to six identical kinematic chains, which provide three (for the tripod) to zero (for the hexapod ...

Dislocation interaction with C in alpha-Fe: a comparison between atomic simulations and elasticity theory [PDF]
, 2008 The interaction of C atoms with a screw and an edge dislocation is modelled at an atomic scale using an empirical Fe-C interatomic potential based on the Embedded Atom Method (EAM) and molecular statics simulations.

A screw theory of static beams [PDF]
Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems. Expanding the Societal Role of Robotics in the the Next Millennium (Cat. No.01CH37180), 2002 We derive the deflection equation of a simple beam using the screw theory. The effects of tension, torsion and bending of the beam can be unified into a single equation. We begin by looking at the compliance matrix for small elements of the beam. This is loosely based on the work by von Mises (1924).

An elastoplastic theory of dislocations as a physical field theory with torsion
, 2002 We consider a static theory of dislocations with moment stress in an anisotropic or isotropic elastoplastical material as a T(3)-gauge theory. We obtain Yang-Mills type field equations which express the force and the moment equilibrium.
