Design of Developable Surfaces Using Optimal Control
(The American Society of Mechanical Engineers (ASME), 2002)This paper formulates the developable surface design problem in an optimal control setting. Given a regular curve b(t) on the unit sphere corresponding to a one-parameter family of rulings, and ... -
Design Modification for Reducing Silent Chain Annoying Noise
(The American Society of Mechanical Engineers (ASME), 2002)In the design of driving systems, silent chains have extensively replaced roller chains thanks to annoying noise problems. For some types of cab-motorcycles, especially sheet-frame cabs, however, ... -
A New Mathematical Model for Geometric Tolerances as Applied to Round Faces
(The American Society of Mechanical Engineers (ASME), 2002)A new mathematical model is presented for representing the tolerances of planar surfaces. The model is compatible with the ASME Standard for geometric tolerances. Central to the new model is ... -
A Finite-Element-Based Method to Determine the Spatial Stiffness Properties of a Notch Hinge
(The American Society of Mechanical Engineers (ASME), 2001)Notch hinges are flexural hinges used to make complex, precise mechanisms. They are typically modeled as single degree-of-freedom hinges with an associated joint stiffness. This is not adequate ... -
Theoretical Model of Metal V-Belt Drives During Rapid Ratio Changing
(The American Society of Mechanical Engineers (ASME), 2001)Today the use of metal V-belt (MVB) on C.V.T. (continuously variable transmission) based systems is the rule in automotive applications. The great advantage of this kind of belt is the capability ... -
Consideration of Moving Tooth Load in Gear Crack Propagation Predictions
(The American Society of Mechanical Engineers (ASME), 2001)Robust gear designs consider not only crack initiation, but crack propagation trajectories for a fail-safe design. In actual gear operation, the magnitude as well as the position of the force ... -
Manufacturability Analysis of Flatness Tolerances in Solid Freeform Fabrication
(The American Society of Mechanical Engineers (ASME), 2001)Increasingly, Solid Freeform Fabrication (SFF) processes are being considered for creating functional parts. In such applications, SFF can either be used for creating tooling (i.e., patterns for ... -
Using the Simulation Model for Identification of the Fatigue Parameters of Hydraulically Driven Log Crane
(The American Society of Mechanical Engineers (ASME), 2001)The present paper introduces a method based on dynamic simulation for determining the fatigue parameters in a hydraulically driven log crane. The parameters that describe the nature of fatigue ... -
Editorial
(The American Society of Mechanical Engineers (ASME), 2001)I am pleased to inform you of four recently appointed Associate Editors: Dr. Ahmed A. Shabana for design automation, Dr. Daniel Yang for mechanisms and robotics; Dr. Ahmet Kahraman for power ... -
Adapting an Articulated Vehicle to its Drivers
(The American Society of Mechanical Engineers (ASME), 2001)A yaw plane model with limited roll-DOF of a five-axle tractor semitrailer is developed to study the open-loop directional dynamics of the vehicle. A driver model incorporating path preview, ... -
A Differential-Geometric Analysis of Singularities of Point Trajectories of Serial and Parallel Manipulators
(The American Society of Mechanical Engineers (ASME), 2001)In this paper, we present a differential-geometric approach to analyze the singularities of task space point trajectories of two and three-degree-of-freedom serial and parallel manipulators. At ... -
