This paper presents a Differential Evolutionary (DE) algorithm for solving multi-objective kinematic problems (e.g., endeffector locations, centre-of-mass and comfort factors). Inverse kinematic problems in the context of character animation systems are one of the most challenging and important conundrums. The problems depend upon multiple geometric factors in addition to cosmetic and physical ...

Article history: Received 1 September 2011 Received in revised form 15 January 2012 Accepted 21 January 2012 Available online 23 February 2012 Manymechanical systems of practical interest contain closed kinematic chains, and aremost conveniently modeled using a set of redundant generalized coordinates. The governing dynamic equations for systems with more coordinates than degrees-of-freedom are...

In the current study, the effects of interactions of the moving loads and the attached mass-spring-damper systems of the composite plates on the resulting dynamic responses are investigated comprehensively, for the first time, using the classical plate theory. The solution of the coupled governing system of equations is accomplished through tracing the spatial variations using a Navier-type sol...

This paper presents a summary of the new semi-analytical integration method presented in [10] for von Mises elastoplasticity model with combined linear isotropic-kinematic hardening within a small deformation range. Solutions for the case of constant strain rate and constant stress rate assumptions are also presented. Furthemore, it is shown how the general solution reduces to the particular ca...

This paper presents design and kinematic analysis for a cable-driven parallel robotic (CDPR) manipulator with four cables, The CDPR manipulator produces a planar motion including two translational and one rotational degrees of freedom. To move the end-effector of CDPR, its kinematic structure is analyzed and the inverse kinematics is formulated in the closed-form solution. The experimental test...

Abstract: This paper is aimed in presenting a study on the kinematic modeling of the Tricept based five-axis vertical machine tool. Since the machine comprises 3-DOF parallel structure and 2-DOF serial wrist kinematic modeling also comprises serial and parallel part. As solution of direct and inverse kinematics of 2-DOF serial wrist is well known the study in this paper will focus on the parall...

We investigate the growth and structure of magnetic fields amplified by kinematic dynamo action in turbulence with non-zero kinetic helicity. We assume a simple Gaussian velocity correlation tensor, which allows us to consider very large magnetic Reynolds numbers, up to 10. We use the kinematic Kazantsev-Kraichnan model of dynamo and find a complete numerical solution for the correlation functi...

The purpose of this special journal issue is to aggregate papers on design issues for the kinematic design of robots by looking at different subjects that can define open problems but new solutions both for design procedures and robot architectures. Kinematic design of manipulators can be understood as related to the definition and computation of the kinematic scheme of the structure of a robot...
