RISDetermining Muscle Forces in the Leg During Normal Human Walking—An Application and Evaluation of Optimization Methods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The individual muscle forces in the leg during human walking are unknown, because of a greater number of muscles when compared to degrees of freedom at the joints. The muscle force-joint ...
A Method for In-Process Failure Prediction in Cold Upset Forging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses the prediction of plastic tensile instability and ductile fracture of a specimen undergoing a compression test (simple upsetting). The method used to predict failure is based ...
Control of a Sequential Brakeforming Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The process of sequential three point bending (or “bumpforming”) is often used to produce smoothly varying simple curvature parts. The process involves bending and incrementing the bend line in ...
Weld Pool Impedance Identification for Size Measurement and Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A primary indicator of weld quality is the size of the bead produced, and for full penetration welds this size parameter can be reduced to the width of the backbead. A method for determining ...
Active Control of Robot Structure Deflections
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The characteristic beam-like structure of most robots leads to significant bending deflections, which in turn lead to poor endpoint positioning accuracy. One solution is to actively counteract ...
A Transfer Function Description of Sheet Metal Forming for Process Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three-dimensional forming of sheet metal parts is typically accomplished using one or two shaped tools (dies) that impart the necessary complex curvature and induce sufficient in-plane strain for ...
A Model of the Sequential Bending Process for Manufacturing Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The process of sequential bending has many applications, but the most common is for developing cylindrical shapes from plate. The objective of this work is to develop a process model for use ...
Real-Time Control of Sheet Stability During Forming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the stamping of complex three-dimensional sheet metal parts, the in-plane compressive stresses created often lead to failure by buckling. These are typically suppressed by binding the ...
Rapid Tooling for Sheet Metal Forming Using Profiled Edge Laminations—Design Principles and Demonstration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sheet metal forming dies constructed of laminations offer advantages over more conventional tooling fabrication methods (e.g. CNC-machining) in terms of tooling accessibility, reduced limitations ...
A Comparison of Rapid Fabrication Methods for Sheet Metal Forming Dies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The need for rapid, low-cost die fabrication and modification methods is greater than ever in the sheet metal forming sector of industry. Consequently, three fabrication methods, suitable for ...
