RISNumerical Synthesis of Six Bar Linkages for Mechanical Computation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a design procedure for sixbar linkages that use eight accuracy points to approximate a specified input–output function. In the kinematic synthesis of linkages, this is known as the synthesis of a ...
Controlling the Movement of a TRR Spatial Chain With Coupled Six Bar Function Generators for Biomimetic Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a synthesis technique that constrains a spatial serial chain into a single degreeoffreedom mechanism using planar sixbar function generators. The synthesis process begins by specifying the target motion ...
Computational Design of Stephenson II Six Bar Function Generators for 11 Accuracy Points
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a design methodology for Stephenson II sixbar function generators that coordinate 11 input and output angles. A complex number formulation of the loop equations yields 70 quadratic equations in 70 ...
A Design System for Eight Bar Linkages as Constrained 4R Serial Chains
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a design system for planar eightbar linkages that adds three RR constraints to a userspecified 4R serial chain. R denotes a revolute, or hinged, joint. There are 100 ways in which these constraints can ...
Analysis of Two Spherical Parallel Manipulators With Hidden Revolute Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we examine two spherical parallel manipulators (SPMs) constructed with legs that include planar and spherical subchains that combine to impose constraints equivalent to hidden revolute joints. The first has ...
A Design System for Six Bar Linkages Integrated With a Solid Modeler
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a design system for planar and spherical sixbar linkages, which is integrated with a solid modeler. The user specifies a backbone 3R chain in five task configurations in the sketch mode of the solid ...
Design of a Linkage System to Write in Cursive
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a design methodology for a system of linkages that can trace planar Bezier curves that represent cursive handwriting of the alphabet and Chinese characters. This paper shows that the standard degree n ...
Design of Mechanisms to Draw Trigonometric Plane Curves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes a mechanism design methodology that draws plane curves which have finite Fourier series parameterizations, known as trigonometric curves. We present three ways to use the coefficients of this ...
Design of a Flapping Wing Mechanism to Coordinate Both Wing Swing and Wing Pitch
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a design procedure to achieve a flapping wing mechanism for a micro-air vehicle that coordinates both the wing swing and wing pitch with one actuator. The mechanism combines a planar four-bar linkage ...
An Adjustable Single Degree of Freedom System to Guide Natural Walking Movement for Rehabilitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a linkage system designed to guide a natural ankle trajectory with the corresponding foot orientation. A sixbar linkage was designed to coordinate the joint angles of an RR chain (R denotes a revolute ...
