    • Editorial 

      J. Michael McCarthy (The American Society of Mechanical Engineers (ASME), 2005)
      This has been a successful year for the Journal of Mechanical Design. The production process, like the review process, has moved to an almost entirely web-based system. We have reduced both ...
    • The Influence of Pulley Deformations on the Shifting Mechanism of Metal Belt CVT 

      G. Carbone; L. Mangialardi; G. Mantriota (The American Society of Mechanical Engineers (ASME), 2005)
      This paper is concerned with the shifting behavior of a metal belt CVT. The calculations are performed for the chain belt case by using a one-dimensional model of the belt: the radial thickness ...
    • Equivalent Kinematic Chains of Three Degree-of-Freedom Tripod Mechanisms With Planar-Spherical Bonds 

      Patrick Huynh; Jacques M. Hervé (The American Society of Mechanical Engineers (ASME), 2005)
      The paper aims to analyze the equivalent kinematic chains of a family of three-degree-of-freedom (3-DOF) tripod mechanisms with planar-spherical bonds in order to determine the platform motions ...
    • Configuration Bifurcations Analysis of Six Degree-of-Freedom Symmetrical Stewart Parallel Mechanisms 

      Yu-Xin Wang; Yi-Ming Wang (The American Society of Mechanical Engineers (ASME), 2005)
      The configuration bifurcations of Stewart parallel manipulators at singular positions induce the uncertainty of the moving trends of the manipulative platform. The Jacobian matrix method can ...
    • An Advanced Method to Correlate Scale Models With Distorted Configurations 

      Uichung Cho; Senior Engineering Manager; Alan J. Dutson; Kristin L. Wood; Richard H. Crawford (The American Society of Mechanical Engineers (ASME), 2005)
      Functional testing of prototypes is a critical step in the development of many of today’s products. Results of functional tests allow for verification of proper performance before a product is ...
    • Tolerance Synthesis of Mechanisms: A Robust Design Approach 

      Stéphane Caro; Fouad Bennis; Philippe Wenger (The American Society of Mechanical Engineers (ASME), 2005)
