Design and Evaluation of a Passive Constant Force Mechanism for a Cardiac Ablation Catheter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Contact force management has been proven to have a positive effect on the outcome of cardiac ablation procedures. However, no method exists that allows maintaining a constant contact force within a required and effective ...
Properties of Twofold Tape Loops: The Influence of the Subtended Angle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tape springs are thin-walled structures with zero longitudinal and constant transverse curvature. Folding them twice and connecting both ends creates a tape loop which acts as a linear guide. At this time, there is ...
Unified Stiffness Characterization of Nonlinear Compliant Shell Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compliant shell mechanisms utilize spatially curved thin-walled structures to transfer or transmit force, motion, or energy through elastic deformation. To design spatial mechanisms, designers need comprehensive nonlinear ...
Shape Optimization Framework for the Path of the Primary Compliance Vector in Compliant Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The primary compliance vector (PCV) captures the dominant kinematic behavior of a compliant mechanism. Its trajectory describes large deformation mechanism behavior and can be integrated in an optimization objective in ...
