RISSimplifying the Development and Usage of Fixtures for Sheet Metal and Composite Aircraft Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on a survey of small- to medium-sized companies that supply sheet metal parts to the major aircraft manufacturers, there is a need for a more simplified, flexible and inexpensive method ...
A Preliminary Study of Sealing and Heat Transfer Performance of Conformal Channels and Cooling Fins in Laminated Tooling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rapid tooling (RT) methods allow for almost complete flexibility in routing of conformal cooling or heating channels within a mold for enhanced thermal control, but tool size is currently ...
A Feasibility Study of Ribbon Architecture for PEM Fuel Cells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The feasibility of an alternative fuel cell architecture, called a ribbon membrane electrode assembly (MEA), is demonstrated for low-temperature polymer electrolyte membrane (PEM) fuel cells used ...
An Inexpensive Weight Bearing Indicator With Load Range Capability for Rehabilitation of Patients With Lower Extremity Injuries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the mechanical behavior and design of a patent pending device called a load range weight bearing indicator (LWBI), which provides upper and lower range indication to ...
An Inexpensive Weight Bearing Indicator Used for Rehabilitation of Patients With Lower Extremity Injuries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Background . Partial or nonweight bearing is a useful treatment prescribed by medical professionals (e.g., orthopedists, podiatrists) for patients rehabilitating from lower extremity injuries However, ...
Structural Modeling of Profiled Edge Laminate (PEL) Tools Using the Finite Element Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Profiled Edge Laminate (PEL) tooling is a rapid tooling method that uses a stacked array of vertically orientated thick laminae with profiled and beveled top edges to provide the desired surface ...
A Hydraulically-Actuated Reconfigurable Tool for Flexible Fabrication: Implementation and Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An automatically reconfigurable discrete tool (matrix of pins) has been developed and demonstrated for sheet metal part forming and composite part molding in the aerospace industry. A GUI-based ...
Fixturing of Compliant Parts Using a Matrix of Reconfigurable Pins
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Commercially-available reconfigurable fixtures, used for holding compliant sheet metal, composite and plastic parts during secondary machining operations, are extremely expensive and overly-complicated ...
Structural Modeling of Profiled Edge Laminae (PEL) Tools
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Profiled Edge Laminae (PEL) tooling is a thick-layer Rapid Tooling (RT) method that involves assembling an array of laminae—each having a uniquely profiled and beveled top edge—together in a ...
Using Reconfigurable Tooling and Surface Heating for Incremental Forming of Composite Aircraft Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The application of composites in the aircraft industry has increased significantly over the past few decades. With traditional composite laminate shaping, each layer is made to conform to the ...
