Dynamic modeling of a slider-crank mechanism with coupler and joint flexibility

open access: yesMechanism and Machine Theory, 1994
Abstract Modeling and dynamic analysis of a slider-crank mechanism with flexible joint and coupler is presented. The equations of motion of the mechanism are formulated using a newly evolving multibody formalism and cast in terms of a minimum set of generalized coordinates through a Jacobian matrix expansion.

A Lie group variational integrator in a closed-loop vector space without a multiplier [PDF]

open access: yesMechanical Sciences
As a non-tree multi-body system, the dynamics model of four-bar mechanism is a differential algebraic equation. The constraints breach problem leads to many problems for computation accuracy and efficiency.

Substantiation of Rational Design of Crank Mechanism of a Wheel-Step Mover

open access: yesМеханика машин, механизмов и материалов
The article substantiates the rational design of the crank mechanism of a wheel-step mover. Kinematics analysis of a prototype of the wheel-step mover revealed the presence of oscillations in the vertical coordinate of the central axis during movement ...

Modeling of Dynamics of Nonideal Mixer at Oscillation and Aperiodic Damped Mode of Driving Member Motion

open access: yesApplied Sciences
The dynamics of the vibrational mode of motion of the driving member of a nonideal system, a mixing–whipping device based on a simple slide-crank mechanism, was studied. The highly nonlinear differential equations of motion were solved numerically by the

A Dynamic Analysis of the Plane Crank-and-Rocker Mechanisms with Clearances

open access: yesBulletin of JSME, 1980
The equations of motion of the plane four-bar mechanisms have been derived for all of possible numbers and positions of clearance-connections except the input-shaft position when the mechanisms rotate at constant speeds in a vertical plane. Applying the equations to a crank-and-rocker mechanism, the effects of the numbers and positions of clearance ...
