Theory for Topology Synthesis of Parallel Manipulators and Its Application to Three-Dimension-Translation Parallel Manipulators
(The American Society of Mechanical Engineers (ASME), 2004)A systematic theory for topology synthesis of parallel manipulators considering basic requirements such as kinematics, dynamics, control, and actuation is built. The kernel part of the theory is ... -
Bistable Configurations of Compliant Mechanisms Modeled Using Four Links and Translational Joints
(The American Society of Mechanical Engineers (ASME), 2004)Bistable mechanical devices remain stable in two distinct positions without power input. They find application in valves, switches, closures, and clasps. Mechanically bistable behavior results from ... -
A Novel Compliant Mechanism for Converting Reciprocating Translation Into Enclosing Curved Paths
(The American Society of Mechanical Engineers (ASME), 2004)This paper introduces a novel contact-aided compliant mechanism that uses intermittent contacts to convert a single translatory reciprocating input into two output curves, which intersect to enclose ... -
A New Cycloid Drive With High-Load Capacity and High Efficiency
(The American Society of Mechanical Engineers (ASME), 2004)A patented double crank ring-plate-type cycloid drive is introduced in this paper. The new drive requires no output unit and places no limit on the size of the tumbler bearing. The drive is ... -
Rigid Body Motion Characteristics and Unified Instantaneous Motion Representation of Points, Lines, and Planes
(The American Society of Mechanical Engineers (ASME), 2004)The article presents a unified algebraic approach for the modeling of the instantaneous motions of all linear elements, such as points, lines, and planes, embedded in a rigid body. The paper ... -
A Combined Penalty and Recursive Real-Time Formulation for Multibody Dynamics
(The American Society of Mechanical Engineers (ASME), 2004)The continuously improved performance of personal computers enables the real-time motion simulation of complex multibody systems, such as the whole model of an automobile, on a conventional PC, ... -
Infinitely Variable Transmission of Racheting Drive Type Based on One-Way Clutches
(The American Society of Mechanical Engineers (ASME), 2004)An infinitely variable transmission (IVT), based on the use of one-way action clutches, belonging to the family of ratcheting drives is described. The mechanical foundations and numerical simulations ... -
An Integrated Framework for Optimization Under Uncertainty Using Inverse Reliability Strategy
(The American Society of Mechanical Engineers (ASME), 2004)In this work, we propose an integrated framework for optimization under uncertainty that can bring both the design objective robustness and the probabilistic design constraints into account. The ... -
A Study of Displacement Distribution in a Piezoelectric Heterogeneous Bimorph
(The American Society of Mechanical Engineers (ASME), 2004)Piezoelectric heterogeneous bimorphs have extensive applications in the MEMS area. In order to formulate their displacement distribution more conveniently, a concise analytical solution is described ... -
New Pneumatic Cylinders for Improving Servo Actuator Positioning Accuracy
(The American Society of Mechanical Engineers (ASME), 2004)Positioning accuracy of pneumatic servo actuators depends on parameters of the actuator and control system, and also on the friction force. This paper reports on new constructions of the pneumatic ... -
Evaluation of the Effect of Misalignment and Profile Modification in Face Gear Drive by a Finite Element Meshing Simulation
(The American Society of Mechanical Engineers (ASME), 2004)Face gear drives have many advantages over other cross axis transmissions especially in high performance applications. The lack of published design experience and design standards make their ... -
An Experimental Study of Self-Loosening of Bolted Joints
(The American Society of Mechanical Engineers (ASME), 2004)The self-loosening process of a bolted joint consists of two distinct stages. The early stage of self-loosening is due to the cyclic plastic deformation of the materials. The second stage of ... -
Transformation of an EGT Grammar: New Grammar, New Designs
(The American Society of Mechanical Engineers (ASME), 2004)True design with grammars lies in the creation of the grammar rules, not in the application of the rules to generate design alternatives. Existing grammars can be modified to describe new ... -
