A Graphical Method to Find the Secondary Instantaneous Centers of Zero Velocity for the Double Butterfly Linkage
(The American Society of Mechanical Engineers (ASME), 2003)The Aronhold-Kennedy theorem cannot locate all of the instantaneous centers of zero velocity for a planar, single-degree-of-freedom, indeterminate linkage. This paper presents a graphical technique ... -
The Computation of All 4R Serial Spherical Wrists With an Isotropic Architecture
(The American Society of Mechanical Engineers (ASME), 2003)A spherical wrist of the serial type with n revolute (R) joints is said to be isotropic if it can attain a posture whereby the singular values of its Jacobian matrix are all equal to n/3. ... -
Freeform Skeletal Shape Optimization of Compliant Mechanisms
(The American Society of Mechanical Engineers (ASME), 2003)Compliant mechanisms are elastic continua used to transmit or transform force and motion mechanically. The topology optimization methods developed for compliant mechanisms also give the shape for ... -
Robustness Evaluation for Compliant Assembly Systems
(The American Society of Mechanical Engineers (ASME), 2003)A new method for evaluating the robustness of compliant assembly systems is developed based on previously developed variation simulation models. This method can be used for selecting a robust ... -
Hybrid Analysis Method for Reliability-Based Design Optimization
(The American Society of Mechanical Engineers (ASME), 2003)Reliability-based design optimization (RBDO) involves evaluation of probabilistic constraints, which can be done in two different ways, the reliability index approach (RIA) and the performance ... -
Identifying Modular and Integrative Systems and Their Impact on Design Team Interactions
(The American Society of Mechanical Engineers (ASME), 2003)The typical approach to developing complex products is to decompose the product into systems, and these into components. We introduce a new notion of system modularity based upon the way ... -
An Economic Design Change Method
(The American Society of Mechanical Engineers (ASME), 2003)New product design as well as design revision to remedy defects is complicated by an inability to precisely predict product performance. Designers often find that they are confident about the ... -
Design of Shaving Cutter for Plunge Shaving a Topologically Modified Involute Pinion
(The American Society of Mechanical Engineers (ASME), 2003)The purpose of this paper is to solve the problem of designing a shaving cutter for plunge shaving a topologically modified involute pinion. Application of topologically modified pinion allows ... -
Backlash Compensation in Gear Trains by Means of Open-Loop Modification of the Input Trajectory
(The American Society of Mechanical Engineers (ASME), 2003)This paper presents an approach to reduce the effect of the backlash nonlinearity in systems with relative cyclic motion. A compensation approach is developed to calculate a modified course of ... -
Singularity Analysis of 3-DOF Planar Parallel Mechanisms via Screw Theory
(The American Society of Mechanical Engineers (ASME), 2003)This paper presents the results of a detailed study of the singular configurations of 3-DOF planar parallel mechanisms with three identical legs. Only prismatic and revolute joints are considered. ... -
A Finite-Element-Based Study of the Load Distribution of a Heavily Loaded Spur Gear System With Effects of Transmission Shafts and Gear Blanks
(The American Society of Mechanical Engineers (ASME), 2003)Spur gears were typically analyzed in the past using two-dimensional (2-D) Finite Element (FE) models. This is not adequate in many cases. A three-dimensional (3-D) FE model of a spur gear ... -
Constraint Singularities of Force Transmission in Nonredundant Parallel Robots With Less Than Six Degrees of Freedom
(The American Society of Mechanical Engineers (ASME), 2003)The analysis of the workspace singularities is one of the fundamental aspects in the design of parallel robots. The architecture singularities are generally studied analysing the local properties ... -
Synthesis of Inertially Compensated Variable-Speed Cams
(The American Society of Mechanical Engineers (ASME), 2003)Traditionally, cam-follower systems are designed by assuming a constant camshaft speed. Nevertheless, all cam-follower systems, especially high-speed systems, exhibit some camshaft speed fluctuation ... -
Adaptive Response Surface Method Using Inherited Latin Hypercube Design Points
(The American Society of Mechanical Engineers (ASME), 2003)This paper addresses the difficulty of the previously developed Adaptive Response Surface Method (ARSM) for high-dimensional design problems. ARSM was developed to search for the global design ... -
