Research on Dynamics Characteristic Influence of Different Clearance of Rotating Pair on Crank-group Driving Mechanism

open access: yesJixie chuandong, 2021
The crank-group driving mechanism is a kind of linkage truss mechanism with redundant constraints. Aiming at the mechanism characteristics,based on the dynamics model of ‘continuous contact model’,a virtual simulation model of the crank-group mechanism ...

Water clustering in polychloroprene [PDF]

open access: yes, 2014
Water sorption has been studied gravimetrically for polychloroprene rubber samples, first at a fixed hygrometric ratio (98% HR) and several temperatures (25, 40, 60 and 80 °C) for samples of 1.8 and 3.8 mm thickness (Constant Temperature and Hygrometry ...

A bouncing ball model with two nonlinearities: a prototype for Fermi acceleration [PDF]

open access: yes, 2007
Some dynamical properties of a bouncing ball model under the presence of an external force modeled by two nonlinear terms are studied. The description of the model is made by use of a two dimensional nonlinear measure preserving map on the variables ...

Dynamic Analysis of the Crank Mechanism through the Numerical Solution [PDF]

open access: yesManufacturing Technology, 2019
Dynamic analysis of crank mechanism is realised by relaxation method, where a connecting rod is modelled with three manners. In the first case the connecting rod is modelled as a rigid body, in the second case this one is modelled with two mass points and in the third case the connecting rod is modelled with three mass points. Results of all manners of

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

A spherical shell numerical dynamo benchmark with pseudo vacuum magnetic boundary conditions [PDF]

open access: yes, 2014
It is frequently considered that many planetary magnetic fields originate as a result of convection within planetary cores. Buoyancy forces responsible for driving the convection generate a fluid flow that is able to induce magnetic fields; numerous ...

Encyclopedia of 2D β′‐In2Se3 Growth Using Chemical Vapor Deposition: The Effects of Synthesis Parameters Onto Material Quality

open access: yesAdvanced Engineering Materials, EarlyView.
A distinct semi‐confined inner‐tube chemical vapor deposition geometry enables reproducible, large‐area growth of phase‐pure 2D β′‐In2Se3 from InI + Se precursors. Engineering local vapor transport and optimizing precursor delivery and temperature–time conditions yield uniform continuous films.
