Assessing Position Order in Rigid Body Guidance: An Intuitive Approach to Fixed Pivot Selection
(The American Society of Mechanical Engineers (ASME), 2009)Several established methods determine if an RR dyad will pass through a set of finitely separated positions in order. The new method presented herein utilizes only the displacement poles in ... -
Evolutionary Multi-Agent Systems: An Adaptive and Dynamic Approach to Optimization
(The American Society of Mechanical Engineers (ASME), 2009)This paper explores the ability of a virtual team of specialized strategic software agents to cooperate and evolve to adaptively search an optimization design space. Our goal is to demonstrate ... -
Should Designers Worry About Market Systems?
(The American Society of Mechanical Engineers (ASME), 2009)We examine how profit-maximizing designs are influenced by two structural aspects of market systems: (1) the structure of manufacturer-retailer interactions and (2) the structure of heterogeneity ... -
Finite Element Based Member Stiffness Evaluation of Axisymmetric Bolted Joints
(The American Society of Mechanical Engineers (ASME), 2009)For a reliable design of bolted joints, it is necessary to evaluate the actual fraction of the external load transmitted through the bolt. The stiffness of the bolt and the member of the ... -
Accuracy Analysis of Parallel Manipulators With Joint Clearance
(The American Society of Mechanical Engineers (ASME), 2009)Due to joint clearance, a parallel manipulator’s end-effector exhibits position and orientation (or collectively referred to as pose) errors of various degrees. This paper aims to provide a ... -
