Parameter identification for joint elements in a revolute-joint detector manipulator

SPIE Proceedings, 2005
A revolute-joint robot is being developed for the spatial positioning of an x-ray detector at the Advanced Photon Source. Commercially available revolute-joint manipulators do not meet our size, positioning, or payload specifications. One idea being considered is the modification of a commercially available robot, with the goal of improving the ...

Joint Commissioning: organisational revolution or misplaced enthusiasm?

Policy & Politics, 1995
One of the paradoxes of the shift towards markets in health and social care has been the renewed emphasis upon more effective collaboration between the professionals and agencies involved. This has led to a search for ways of developing a range of joint ventures such as information sharing, joint community care planning and joint assessment of needs ...

Modeling 3D revolute joint with clearance and contact stiffness

Nonlinear Dynamics, 2011
The clearances in the kinematic joints are due to deformations, wear, and manufacturing errors; the accurate modeling of these effects in multibody analysis is a complex issue but in many practical applications, it is mandatory to take into them into account in order to understand the actual behavior of mechanical systems.

Did the MillerCoors Joint Venture Strengthen the Craft Beer Revolution?

SSRN Electronic Journal, 2021
In this paper, we study the effect of the MillerCoors joint venture on craft brewers in the United States. Using a detailed scanner data set, which covers 1,739 grocery stores located in 33 cities, we track the assortment and the market share of craft beers that were offered from 2001 until 2011.

Axisymmetric General Shells and Jointed Shells of Revolution

Journal of Structural Engineering, 1992
An iterative numerical method is presented for the analysis of axisymmetric, isotropic general shells with varying wall rigidity. Shell elements of special geometric shapes, e.g., cylindrical, spherical, and conical shells, are also considered. One-dimensional finite difference points are used to discretize the shell elements into strips along the ...

The maximum reach of revolute jointed manipulators

Mechanism and Machine Theory, 1981
Abstract The maximum reach of a manipulator consisting of 3 or more revolute joints is achieved when the line connecting the hand to the base is made to intersect all the intermediate joint axes. By a one to one mapping, the working volume can be generated.

Shape Optimization of Revolute-Jointed Rigid-Flexible Manipulator

Journal of The Institution of Engineers (India): Series C, 2014
This work illustrates the shape optimization of flexible link of revolute-jointed rigid-flexible manipulator. Flexible link is considered as Euler–Bernoulli beam and dynamic analysis is carried out by finite element based on Langrange approach. Nonlinear classical search technique (Sequential Quadratic Programming method) is applied to extremize the ...

Dynamic response of a revolute joint with clearance

Mechanism and Machine Theory, 1996
The response of a revolute joint in a four-bar mechanism with a clearance is investigated. Motion of a rocker-arm pin at the ground connection is modelled using a Lagrangian approach. When the resulting equations of motion are solved numerically, they show non-linear dependence on both the size of the clearance and the coefficient of friction between ...

Preliminary design of a revolute to prismatic morphing compliant joint

Transactions of the Canadian Society for Mechanical Engineering, 2020
The reduction of weight and size of mechanisms are important and difficult challenges considering portability, energy efficiency, and simplicity of fabrication. One of the solutions to address these issues consists of mechanisms with variable topology for which the mobility of the output is a succession of several simpler elementary motions.

A study of manipulator with passive revolute joint

Artificial Life and Robotics, 2008
In this article, equations of motion of a manipulator, whose mechanism has a passive revolute joint, are derived in consideration of the characteristics of driving source. Considering the fi nal condition of displacement and velocity of the passive joint, trajectories of velocity for energy saving are calculated by iterative dynamic programming.
