Comparative Study on Calculation Method of Contact Force in Joint with Clearance of Crank Slider Mechanism

open access: yesJixie chuandong, 2021
In order to select the best contact force calculation method for the dynamics performance analysis of multibody systems involving joints with clearance, a dynamics model of a crank slider mechanism involving joints with clearance is established and a ...

Equilibrium Analysis and Simulation Calculation of Four-Star Type Crank Linkage Mechanism

open access: yesMachines, 2023
Unbalanced inertia force is inevitably generated during the operation of crank linkage. It is one of the main excitation sources of air compressor vibration and the focus of managing air compressor vibration noise.

Deformation Control in Rest-to-Rest Motion of Mechanisms with Flexible Links [PDF]

open access: yes, 2018
This paper develops and validates experimentally a feedback strategy for the reduction of the link deformations in rest-to-rest motion of mechanisms with flexible links, named Delayed Reference Control (DRC). The technique takes advantage of the inertial

Nonlinear Dynamics and Control of Crank-Slider Mechanism with Multiple Clearance Joints [PDF]

open access: yesJournal of Theoretical and Applied Vibration and Acoustics, 2015
In the current study, behavior of crank-slider mechanism with single and multiple clearance joints are analyzed. Using Lankarani-Nikravesh theory for estimating discontinuous contact forces in clearance joints, relevant systems have been mathematically ...

Simulation of a stationary dark soliton in a trapped zero-temperature Bose-Einstein condensate [PDF]

open access: yes, 2006
We discuss a computational mechanism for the generation of a stationary dark soliton, or black soliton, in a trapped Bose-Einstein condensate using the Gross-Pitaevskii (GP) equation for both attractive and repulsive interaction.

Dynamic Simulation of Crank-group Driving Mechanism with Clearance

open access: yesInternational Journal of Online and Biomedical Engineering (iJOE), 2016
The crank-group driving mechanism includes a group of redundant constraints. This mechanism can move as a driving mechanism under ideal conditions, but it may be stuck because of the processing errors in practical applications. So, some clearances are reserved between the pin hole and the pin to ensure that the crank-group driving mechanism can achieve

Mathematical modeling kinematics of double toggle jaw crusher

open access: yesГірничі, будівельні, дорожні та меліоративні машини, 2023
In this work, the problem of modeling the kinematic parameters of a jaw crusher with a simple movement of the jaw was consider. The dynamic model of the jaw crusher was consider as a flat articulated-lever closed mechanism. The crushing mechanism of the

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 ...

A RECONSTRUCTION OF THE GREEK-ROMAN REPEATING CATAPULT [PDF]

open access: yes, 2010
An “automatic” repeating weapon used by the Roman army is presented. Firstly a short description is shown of the working principle of the torsion motor that powered the Greek-Roman catapults.
