    • Saddlepoint Approximation for Sequential Optimization and Reliability Analysis 

      Xiaoping Du (The American Society of Mechanical Engineers (ASME), 2008)
      A good balance between accuracy and efficiency is essential for reliability-based design (RBD). For this reason, sequential-loops formulations combined with the first-order reliability method (FORM) ...

    • Linkage Mechanisms With Cam-Integrated Joints for Controlled Harmonic Content of the Output Motion: Theory and Application

      In a recent study, the authors presented a systematic method for the modification of the output motion of linkage mechanisms with closed-loop chains using cams positioned at one or more joints ...

    • Causes of Microslip in a Continuously Variable Transmission 

      Songho Kim; Carl Moore; Michael Peshkin; J. Edward Colgate (The American Society of Mechanical Engineers (ASME), 2008)
      The continuously variable transmission (CVT) is a type of transmission that can adopt any arbitrary gear ratio. Whereas typical transmissions utilize toothed gears, the CVT employs a sphere in ...

      The position analysis of a nine-link Barranov truss is finished by using Dixon resultants together with Sylvester resultants. Above all, using vector method in complex plane to construct four ...

    • Designing Synchronous Belt Transmissions With Variable Velocity Ratio 

      Carlo Innocenti; Davide Paganelli (The American Society of Mechanical Engineers (ASME), 2008)
      The paper presents a new procedure to design a two-pulley synchronous belt transmission connecting, with no belt tensioner, two parallel-axis shafts with a variable velocity ratio. The procedure ...

    • An Analytical Contact Model for Design of Compliant Fingers 

      Chao-Chieh Lan; Kok-Meng Lee (The American Society of Mechanical Engineers (ASME), 2008)
      A compliant gripper gains its dextral manipulation by the flexural motion of its fingers. It is a preferable device as compared to grippers with multijoint actuations because of reduced fabrication ...

    • The Kinematics of Wheeled Mobile Robots With Dual-Wheel Transmission Units 

      Chao Chen; Svetlana Ostrovskaya; Jorge Angeles (The American Society of Mechanical Engineers (ASME), 2008)
      The dual-wheel transmission unit, an innovative driving mechanism for wheeled mobile robots, was introduced elsewhere. In this paper, we discuss wheeled mobile robots with such units, supplied ...

    • A Building Block Approach to the Conceptual Synthesis of Compliant Mechanisms Utilizing Compliance and Stiffness Ellipsoids 

      Charles J. Kim; Yong-Mo Moon; Sridhar Kota (The American Society of Mechanical Engineers (ASME), 2008)
      In this paper, we investigate a methodology for the conceptual synthesis of compliant mechanisms based on a building block approach. The building block approach is intuitive and provides key ...

    • Experimental Validation of Input Torque Balancing Applied to Weaving Machinery 

      Stephan Masselis; Philip Cornelissen; Gregory Pinte; Jan Hemelsoen; René Boonen; Kristof Roelstraete; Wim Desmet; Bram Demeulenaere; Pieter Spaepen; Jan Swevers; Joris De Schutter (The American Society of Mechanical Engineers (ASME), 2008)
      This paper considers a class of high-speed airjet weaving machines that is characterized by excessive harness frame vibration, resulting in premature failure. This problem is tackled through ...

    • A Method for Integrating Form Errors Into Geometric Tolerance Analysis 

      Robert Scott Pierce; David Rosen (The American Society of Mechanical Engineers (ASME), 2008)
      In this research, we describe a computer-aided approach to geometric tolerance analysis for assemblies and mechanisms. A series of as-manufactured component models are generated within a NURBS-based ...

    • A Sequential Algorithm for Possibility-Based Design Optimization 

      Jun Zhou; Zissimos P. Mourelatos (The American Society of Mechanical Engineers (ASME), 2008)
      Deterministic optimal designs that are obtained without taking into account uncertainty/variation are usually unreliable. Although reliability-based design optimization accounts for variation, it ...

    • Automatic Fairing of Two-Parameter Rational B-Spline Motion 

      Anurag Purwar; Xiaoyi Chi; Qiaode Jeffrey Ge (The American Society of Mechanical Engineers (ASME), 2008)
      This paper deals with the problem of automatic fairing (or fine-tuning) of two-parameter rational B-spline spherical and spatial motions. The results presented in this paper extend the previous ...

    • Stiffness Characteristics of Carton Folds for Packaging 

      Jian S. Dai; Ferdinando Cannella (The American Society of Mechanical Engineers (ASME), 2008)
      Recent studies for packaging using cartons have modeled carton folds as equivalent mechanisms by considering creases as revolute joints and panels as links. This raises the interest in the study ...

    • A Note on the Shear Influence on Belt Drive Mechanics 

      F. Sorge (The American Society of Mechanical Engineers (ASME), 2008)
      Belt drives work often with short center distances and very different wrap arcs so that high adherence characteristics are required at the belt-pulley contact. In addition, the belt flexural ...
